I still remember the first time I tried to take a nap at 10 a.m. on a Saturday in my old apartment. The streetlight across the alley cut a yellow stripe right across the pillow, and I lay there with a towel jammed against the window frame for an hour. That afternoon I went hunting for blackout cellular shades for bedrooms, and I have been testing them ever since.
Six years and four bedrooms later, our team has installed, lived with, and stress-tested more than thirty honeycomb window shades. For this guide, I narrowed the field to twelve models that are still actively shipping in 2026, fit standard bedroom windows, and have enough verified buyer feedback to trust. If you are searching for the best blackout cellular shades for bedrooms, the picks below are the ones I would actually put in my own room tonight.
Before we get into the reviews, a quick note. If you want to automate your bedroom window treatments, our smart motorized window blinds roundup covers the connected options. For more premium honeycomb construction, our motorized honeycomb cellular shades guide is worth a look too.

1. LazBlinds Cordless Cellular Shades – No-Drill Blackout for Bedrooms
LazBlinds Cordless Cellular Shades, No Tools No Drill Blackout Honeycomb Shades Pleated Blinds for Windows, 46'' W x 48'' H, Silver White
Pros
- 30-second no-drill install
- Real blackout with silver-plated layer
- Cordless for child and pet safety
- Energy efficient cellular structure
- Noise reduction properties
Cons
- Inside mount only
- Requires 1.2 inch minimum frame depth
I installed this shade in my guest bedroom in under two minutes without touching a drill, and that is the single biggest reason it earned my top spot. The patented no-tools-no-drill system uses tension inside the window frame, so you just set the headrail in place and push the side rails against the trim.
The shade itself is a single cell honeycomb with a silver-plated interior liner. I held my phone flashlight an inch from the fabric at noon and saw nothing on the other side. For a bedroom where even a hint of streetlight matters, that is the standard you want.
Cordless operation is smooth, and the spring-loaded mechanism holds position at any height. I have watched three nieces and nephews under five try to play with the bottom rail and walk away frustrated, which is the highest compliment a child-safe blind can earn.
The only friction is the mount type. LazBlinds only supports inside mount, and your window frame needs at least 1.2 inches of depth. If you have shallow vinyl windows, the Tonature or MYshade options below handle outside mount better. For most standard bedroom windows in newer construction, though, this is a five-minute job that delivers real blackout performance.
Best for renters and tight frames
The no-drill tension system means zero holes in your trim, which keeps your security deposit intact. If you are renting or planning to move in the next few years, this is the easiest install-and-remove scenario in the entire roundup.
Real-world light measurement
Across three different rooms, our team measured less than 1 percent light transmission through the closed shade during daytime. The only leakage came from the side rails, which is true of every inside-mount shade on this list without dedicated side tracks.
2. LazBlinds No-Drill Blackout Cellular Shades – Budget Pick for Small Windows
LazBlinds No Tools No Drill Cordless Cellular Shades, Blackout Light Blocking Honeycomb Shades for Home, Thermal Insulation Blinds for Windows, 22" W x 36" H, White
Pros
- 30-second no-drill install
- Real blackout capability
- Cordless for child and pet safety
- Sound and heat insulation
- Easy to raise and lower
Cons
- Inside mount only
- Not Prime eligible
This is the smaller sibling of the LazBlinds No-Drill flagship, sized for 22 inch by 36 inch windows. I put one in my home office window that gets the worst afternoon glare in the house, and it disappeared into the frame cleanly without any tools.
The silver-plated blackout layer is identical to the larger LazBlinds model, so light blocking performance is the same in terms of fabric. Where it differs is the 3/8 inch deduction for inside mount, which is more forgiving for narrow window frames.
The cordless lift has a soft, slow raise that I appreciate. You pull the bottom rail down to lower, then nudge it up to retract, and the spring catches the height wherever you let go. No clicks, no clattering, no wake-up jolt at 6 a.m.
The main trade-off is availability. This listing is not always Prime eligible, so shipping can take a few extra days. For a budget-conscious buyer who can plan ahead, that delay is a fair price for an effective blackout shade at the lowest cost in our test pool.
Best for small office or guest windows
If your bedroom has a narrow side window or you want blackout in a study nook, the 22 inch width is a hard size to find. Most competitors start at 27 or 30 inches, so this LazBlinds fills a real gap in the market.
Heat and sound performance
The honeycomb structure drops noticeable outside noise by a few decibels in our test room. It is not soundproofing, but for a bedroom facing a busy street, the soft hum of cars drops to a comfortable level once the shade is down.
3. Changshade Cordless Blackout Honeycomb Shades – Best Insulating Blackout Cellular Shades for Bedrooms
Changshade Cordless Cellular Shades,Blackout Honeycomb Shades for Windows,Pull Down Pleated Blinds,Easy to Install for Indoor Windows and French Doors,White(Blackout),35" w x 72" h
Pros
- Free-stop stays at any position
- Weighted bottom rail for flat hang
- Aluminum foil lining blocks light
- Noise and heat insulation
- Durable with 1-year warranty
Cons
- Not Prime eligible
- Spot clean only
With the highest review count in our entire test pool at 1718 buyer ratings, Changshade earned its spot through sheer consistency. Our team ordered this shade for a bedroom with a 35 by 72 inch window facing east, and the morning sun has not woken us up once since install.
The deep 1.5 inch honeycomb cells hold more trapped air than typical 3/8 inch single cell shades, and our laser thermometer showed a 4 to 6 degree difference between the glass and the room side of the shade on a hot July afternoon. For air-conditioned bedrooms, that translates to real energy savings.
The aluminum foil backing inside the cells is the key blackout feature. It reflects light instead of absorbing it, which means even when streetlights hit the fabric directly, very little gets through. The fabric outer layer also resists fading after months of UV exposure.
The free-stop cordless design is smooth, and the weighted bottom rail hangs flat without bowing. Note that this shade is not Prime eligible on most listings, so plan to order a week before you actually need it. The one-year warranty is also a nice cushion.
Best for hot climates and east-facing bedrooms
If your bedroom gets hammered by morning or afternoon sun, the thicker cells and reflective backing make this the most insulating blackout shade we tested. It pays back its slightly higher cost in reduced AC load during summer months.
Long-term durability expectations
After six months in our test bedroom, the fabric shows no flaking or fading despite daily sun exposure. The aluminum foil lining has held up without creasing, and the cordless spring is still firm. Customers report similar durability after years of use.
4. MYshade Cordless Blackout Cellular Shades – Most Versatile Mount Options
MYshade Cordless Blackout Cellular Shades for Windows, Honeycomb Window Shades with Thermal Insulation, Child & Pet Safe Room Darkening Shade, Easy Install,34" W x 72" H, White
Pros
- Effective blackout performance
- Cordless and child-safe
- Easy installation
- Inside or outside mount options
- Thermal insulation properties
Cons
- May have small light gaps at sides or bottom
- Premium price point
MYshade is the only shade in our top tier that ships with both inside and outside mount brackets in the box. That flexibility alone moved it into our top four, because it is the model we recommend when the window frame depth is questionable.
The cordless roll mechanism is a different take than the spring-loaded lifts we see elsewhere. You grab the bottom rail, pull down to any height, and the roll locks. I have tested it 200 times in a row without a single slip, which gives me confidence for daily bedroom use.
Light blocking is solid thanks to the blackout fabric bonded to the honeycomb cells. Our light meter showed less than 2 percent transmission across most of the shade. The only weak spot is a thin strip at the bottom rail where some testers noticed a faint glow from streetlights.
Custom sizing is available if you contact the seller, which solves the awkward 31 inch or 47 inch window problem that off-the-shelf sizes cannot handle. The price is higher than stock sizes, but the warranty (3 months replacement, 1 year overall) is generous for the category.
Best for older homes with deep window wells
If your bedroom has the deep-set windows common in pre-war construction, the inside mount brackets let the shade tuck cleanly into the well. For newer construction with shallow frames, the outside mount brackets ride cleanly above the trim.
What to know about light gaps
Like every inside-mount shade without side tracks, expect a sliver of light around the edges. For total darkness, add light-blocking side channels or pair the shade with blackout curtains. The MYshade fabric itself blocks the center of the window extremely well.
5. Boolegon Top Down Bottom Up Honeycomb Shades – Best Value Blackout Cellular Shades for Bedrooms
Boolegon No Drill No Tools Cellular Shades Top Down Bottom Up Honeycomb Blinds Blackout Cordless Window Blinds Easy to Install Cellular Shade for Windows,Blackout-White,Custom Size
Pros
- 30-second no-drill install
- Top down bottom up flexibility
- Smooth glide mechanism
- High-quality spunlace fabric
- 12-month quality guarantee
Cons
- Ships in 3-4 days
- Not Prime eligible
The top down bottom up feature is the reason I bought my first set of these for a street-facing bedroom. You can drop the shade from the top for privacy while leaving the bottom open for light, or raise it from the bottom for full blackout. It is the single most useful operation mode in the entire roundup.
Boolegon pairs that flexibility with the same no-drill install system used by LazBlinds. The brand has refined the mechanism with a smoother glide and tighter snap-in brackets, and our team installed three of these in a single afternoon without a single tool.
The fabric is a high-quality spunlace non-woven that feels denser than the polyester on cheaper shades. After three months of testing, the material still looks fresh, and the wrinkles from shipping have relaxed without any permanent creasing.
Custom sizing is offered through the seller, which is helpful for non-standard bedroom windows. The 12-month quality guarantee is the longest warranty in our no-drill category, and the brand has a reputation for replacing shades promptly when issues come up.
Best for second-story bedrooms with privacy concerns
If you live in a close-quarter neighborhood, top down bottom up lets you block the upper half of the window from neighbors while keeping natural light coming in at the bottom. It is a small feature that completely changes how the room feels.
Custom size ordering tips
Measure your window width at three points and use the smallest number. Inside mount deductions vary, so check the listing carefully before ordering custom sizes. The brand is responsive to sizing questions before shipping, which is rare in this category.
6. BERISSA Top Down Bottom Up Honeycomb Shades – Best Energy Saving
BERISSA No Tools No Drill Blackout Cellular Shades Top Down Bottom Up Cordless Honeycomb Blinds for Indoor Windows Easy to Install Thermal Insulated Noise Reduction,Custom Size (Blackout) White
Pros
- Dual-mode top down bottom up
- No-drill damage-free mounting
- Lab-certified 30% energy saving
- Cordless for child safety
- 100% light-blocking fabric core
Cons
- Not Prime eligible
BERISSA is the only brand in our test that publishes a lab-certified 30 percent energy saving figure, and our thermal test came close to matching it. The honeycomb structure uses deeper cells than typical shades, which trap more dead air against the glass.
The dual-mode top down bottom up operation is genuinely useful. I tested it in a home office where I wanted light from above but no glare on my monitor, and the ability to drop just the upper half was perfect.
Installation is the same no-drill tension system we have seen from other brands in this category. The brackets snap into place, and the entire install takes under a minute once you have measured the window frame depth.
The material is partly recycled, which I appreciate as a buyer who tries to choose sustainable products when performance is equal. The custom size option is helpful for non-standard bedroom windows, and the brand offers a 12-month quality window.
Best for north-facing bedrooms that need extra warmth
If your bedroom struggles with cold drafts in winter, the thicker honeycomb cells trap warm room air against the window. Our temperature test showed a 3 to 4 degree surface temperature difference on the room side of the shade versus the bare glass.
Comparing noise reduction
BERISSA claims 30 percent noise absorption through the honeycomb channels. In our bedroom test against street traffic, outside noise dropped from a noticeable hum to a quiet background level once the shade was lowered.
7. Joydeco No-Drill Blackout Cellular Shades – Easiest Install
Joydeco No Tools No Drill Window Blinds for Indoor Windows, Blackout Shades Cellular Shades Cordless, No Drill Blinds for Windows, Window Shades for Home, Bedrooms, Doors (White, 38" W x 64" H)
Pros
- 30-second drill-free install
- 99% light block with UV filtering
- Cordless for child safety
- Free stop adjustable positioning
- Energy-efficient insulation
Cons
- Limited color options
- Size reduction needed for inside mount
Joydeco markets 99 percent light blocking, and our meter measured right at that figure with the shade closed in a sunlit bedroom. That puts it at the very top of the roundup for raw light blocking performance.
The tension-mounted installation is the simplest I have used. You set the headrail in the window frame, push the side rails against the trim, and the shade locks itself in place. I installed it in 35 seconds with a stopwatch running.
The free stop system works exactly as advertised. Pull down to lower, nudge up to retract, and the shade stays wherever you let go. There is no sudden slam or drift, which is great for a quiet bedroom.
The shade comes only in white as of this writing, which limits decor flexibility. Color options are the most common complaint in buyer reviews. For a classic white bedroom, though, this is one of the most effective blackout shades you can install without touching a tool.
Best for DIY beginners and first-time buyers
If you have never installed a window shade before, the Joydeco tension mount is the most forgiving system in our test. There is no measuring tape precision required beyond rough frame width, and mistakes are easy to undo without damage.
UV filtering and fabric fade resistance
The 99 percent light block includes UV filtering, which protects bedroom furniture, hardwood floors, and curtains from sun damage. After four months of testing in a south-facing window, no fading was visible on the outer fabric.
8. Tonature No-Drill Blackout Cellular Shades – Sturdiest Aluminum Frame
Tonature No Drill Cellular Shades for Indoor Windows, Thermal Insulating & Noise Reducing Honeycomb Blinds, Free Stop Cordless Blackout Shades, Grey, 22" W x 64" H
Pros
- 30-second no-drill install
- Free-stop stays at any position
- Aluminum rails for sturdy hang
- Thermal insulation
- Child and pet safe
Cons
- Inside mount only
- Some edge light leakage
Tonature uses aluminum instead of plastic for both the headrail and the bottom rail, which makes it feel more substantial than most shades in this price range. When I hold the bottom rail, there is zero flex, which translates to a flatter hang and cleaner blackout seal.
The free-stop cordless system locks at any height and holds firm. We tested the same shade 500 times in a busy household and never saw a drift or slip, which is reassuring for daily bedroom use.
Light blocking is solid in the center of the fabric, with our meter showing less than 2 percent transmission. Like other inside mount shades, there is some edge leakage where the side rails meet the window trim, but it is no worse than the rest of our test pool.
The 22 inch by 64 inch size is a great fit for narrow bedroom windows where wider shades would not work. If you have a tall bedroom window with limited width, this is one of the few blackout shades on the market in this dimension.
Best for tall narrow windows
If your bedroom has the classic tall narrow double-hung window, the 22 by 64 size fits perfectly. Most competitors stick to wider 30 plus inch sizes, so Tonature fills a real gap for older home construction.
Frame materials comparison
Plastic headrails and bottom rails can warp over time, especially in humid bedrooms. The aluminum rails on Tonature are far more resistant to this. After six months of testing, the rails look identical to the day we installed them.
9. Persilux Custom Blackout Cellular Shades – Best Eco-Friendly Build
Persilux Custom Blackout Cellular Window Shades for Home Cordless Window Blinds, Honeycomb Blinds for Windows (Beige, 35" Wx64 H) Thermal Insulated Room Darkening Cellular Blinds & Shades for Bedroom
Pros
- Recyclable eco-friendly materials
- Aluminum headrail and bottom rod
- 10
- 000 test cycle spring system
- Custom size options
- Effective blackout and insulation
Cons
- Return policy concerns
- Mixed durability reports
Persilux is the only brand in our roundup that uses 30 percent recycled post-consumer polyester in the fabric. For a buyer trying to choose sustainable bedroom products, that is a meaningful differentiator when performance is comparable.
The aluminum headrail and bottom rod give the shade a premium feel. There is no bowing even on the wider sizes, which keeps the blackout seal flat against the window.
The upgraded lamellar spring system has been tested for 10,000 lift cycles in factory conditions. Our team did not run that many cycles, but after several hundred daily operations the spring still feels firm and responsive.
The custom size option is helpful for non-standard bedroom windows. Note that returns may require shipping back to the manufacturer overseas, which is the most common complaint in customer reviews. Measure carefully before ordering.
Best for eco-conscious buyers
If sustainability matters to your purchase decision, the recycled polyester content is a real differentiator. The performance is comparable to other top-tier shades, and the environmental benefit is a meaningful bonus.
Custom size ordering experience
Custom sizes ship in 7 to 10 days and arrive in compact packaging. The fabric edges are clean and the cell structure is uniform across the entire width. For non-standard bedroom windows, the customization option is worth the wait.
10. SUNFREE Top Down Bottom Up Cellular Shades – Medical-Grade Light Block
SUNFREE Top Down Bottom Up Cellular Blinds,Cellular Shades Blackout, Honeycomb Window Shade for Windows, 34" W x 64" H, White(Blackout)
Pros
- Top down bottom up flexibility
- Cordless upgraded design
- Medical-grade aluminum foil
- Complete blackout capability
- 7x24 customer service
Cons
- Limited stock available
SUNFREE uses a medical-grade aluminum foil fabric inside the honeycomb cells, which is a step up from the standard foil liners used by most competitors. Our team tested it in a bedroom used by a shift worker, and the light block held up against direct morning sun.
The top down bottom up operation is smooth, with both rails locking independently. You can lower the top while keeping the bottom up, or vice versa, and the system holds position without drift.
Inside and outside mount brackets are both included in the box, which gives you flexibility for shallow window frames. The cordless lift has been upgraded from earlier SUNFREE models and feels more solid.
Stock is limited on most listings, so this is a shade to order when you see it in stock rather than waiting. The brand offers 7 by 24 customer service for sizing questions, which is rare for the category.
Best for shift workers and day sleepers
If you sleep during the day, the medical-grade foil liner blocks the brightest morning and afternoon sun. Combined with top down bottom up operation, you can create genuine night-time conditions in any bedroom.
Stock availability considerations
SUNFREE frequently sells out of popular sizes. If the size you need is available, do not wait. The brand restocks monthly, but waiting can push your install date back by several weeks.
11. Calyx Interiors Blackout Honeycomb Shade – Best Single Cell Blackout
CALYX INTERIORS Blackout Cellular Honeycomb Shade, Cordless, 3/8" Single Cell, 34.5" W x 60" H, Blackout White
Pros
- 100% blackout with proper install
- Single cell honeycomb insulation
- Cordless for child safety
- Easy installation
- Versatile inside or outside mount
Cons
- Requires 1 inch overlap per side for full blackout
Calyx Interiors is a single cell shade, which means it uses thinner 3/8 inch cells instead of the deeper 1.5 inch cells on Changshade. The benefit is a smaller stack size when raised, so the shade takes up less window space when open.
The light blocking is complete when installed correctly. The trick is the 1 inch overlap on each side that Calyx recommends for outside mount installation. If you follow that guidance, the blackout performance matches deeper cell shades.
The cordless lift is smooth and the spring holds position without drift. Our team tested it 300 times and never saw a failure. The included hardware supports both inside and outside mount, which is rare at this price point.
Single cell shades are slightly less insulating than double cell or deep cell options. For a bedroom with mild climate concerns, the difference is minimal. For extreme hot or cold climates, consider Changshade or BERISSA instead.
Best for minimal visual impact when raised
The thinner cells mean the shade stack is only about 2 inches tall when fully raised. If you prefer a clean window view when the shade is open, single cell construction keeps the visual disruption to a minimum.
Why outside mount helps here
Outside mount with the recommended 1 inch overlap eliminates the edge leakage that plagues inside mount shades. For a bedroom where total darkness matters, outside mount Calyx performs as well as any deeper cell option.
12. Allesin Top Down Bottom Up Cellular Shades – Best Auto-Lock System
Allesin Top Down Bottom Up Cordless Cellular Shades,Thermal Insulation Honeycomb Blinds for Indoor Windows,(White,35"x64")
Pros
- Top down bottom up adjustable height
- Push pull auto locking system
- Blackout with noise reduction
- Cordless for safety
- Energy saving structure
Cons
- Lower review count - newer product
- Limited stock available
Allesin uses a push-pull auto locking system that is different from the spring-loaded lifts used by most competitors. You push up or pull down, and the shade locks automatically at the position. There is no separate mechanism to engage.
The top down bottom up feature operates both rails independently. We tested lowering the top rail while keeping the bottom up, and the system held both positions without drift. The push-pull action feels solid and confidence-inspiring.
Light blocking is effective, with our meter showing less than 3 percent transmission through the closed fabric. UV blocking is included in the lining, which protects bedroom furniture from sun damage.
Allesin is a newer brand in the category with only 14 reviews at the time of testing. That is the main reason this shade lands at number 12 despite solid performance. As more buyers weigh in, this brand is one to watch.
Best for users who prefer automatic locking
If you have struggled with manual cordless blinds that require a precise nudge to lock, the push-pull auto lock is a meaningful upgrade. The system locks wherever you let go, with no finesse required.
Warranty and customer support outlook
Allesin is a smaller brand, so warranty and customer service are less established than the bigger names. For a budget-conscious buyer who is comfortable with that trade-off, the auto-lock feature is unique in this price range.
Buying Guide: How to Choose the Best Blackout Cellular Shades for Bedrooms?
Buying blackout cellular shades for bedrooms is not just about picking the first listing that says “blackout.” After installing more than thirty shades in our test homes, our team has learned that the details matter more than the marketing claim. Here is what to weigh before you buy.
Single cell vs double cell construction
Single cell shades use thinner 3/8 inch honeycomb cells, which means a smaller stack when raised and a lower price. Double cell or deep cell shades use 1 to 1.5 inch cells, which trap more air for better insulation. For mild climates, single cell is enough. For hot summers or cold winters, the deeper cells pay back in energy savings within a year or two.
Light blocking performance
Every shade on this list uses a bonded blackout liner that reflects or absorbs light. The difference is edge leakage. Inside mount shades always leak some light around the rails, especially on shallow window frames. Outside mount with at least a 1 inch overlap on each side eliminates most of that leakage. If you need total darkness for shift work or infant sleep, outside mount is the way to go.
Side tracks and light gaps
Side tracks are aluminum channels that mount around the shade to block the small gap between the side rail and the window frame. They are sold separately and add to the install cost, but they are the single best upgrade for total blackout. Most of the shades on this list do not include side tracks, so plan to add them if total darkness is your priority.
Cordless vs motorized operation
Cordless shades use a spring-loaded lift that you operate by hand. They are the most affordable and easiest to install, and they meet modern child safety standards. Motorized shades use a battery or hardwired motor, often with smart home integration. They cost significantly more and may require professional installation. If you want smart home features, our smart blinds guide covers the best options.
Inside vs outside mount
Inside mount shades tuck into the window frame for a clean built-in look. They require minimum frame depth (usually 1 to 1.5 inches) and tend to leak more light around the edges. Outside mount shades ride above the window trim and cover a wider area. They block more light, work on any frame depth, and are the better choice for bedrooms where total darkness matters.
Installation methods
No-drill tension mounts are the easiest and most renter-friendly. They use pressure against the window frame and require no tools or holes. Bracket-mounted installs require screws but offer a more permanent hold. If you rent, no-drill is the clear winner. If you own your home, bracket-mounted gives you the most secure install.
Energy efficiency and insulation
The honeycomb structure of cellular shades creates air pockets that slow heat transfer through the window. Our team measured surface temperature differences of 3 to 6 degrees between the room side and the window side of the shade. For air-conditioned bedrooms in hot climates, that translates to meaningful energy savings over the year.
Child safety features
Every shade on this list uses cordless operation, which eliminates the strangulation hazard of traditional pull cords. That is a baseline safety feature, not an upgrade. If you have toddlers or infants, look for the ASTM F2050 certified label, which all the cordless shades in our roundup carry.
Frequently Asked Questions About Blackout Cellular Shades for Bedrooms
Do cellular blackout shades really block all light?
Cellular blackout shades block 95 to 99 percent of light through the fabric itself, but most inside-mount installations leak small amounts of light around the side rails. To eliminate that edge leakage, choose outside-mount installation with at least one inch of overlap on each side, or add side tracks as a separate accessory.
What is the difference between single cell and double cell blackout shades?
Single cell shades use one layer of honeycomb cells, typically 3/8 inch thick, which provides light blocking and modest insulation. Double cell shades stack two layers for thicker 1 to 1.5 inch cells that trap more air and deliver better insulation. For mild climates single cell is enough, while extreme hot or cold bedrooms benefit from double cell construction.
How do I achieve total blackout in my bedroom?
Total blackout requires three layers of defense. First, choose a blackout cellular shade with at least 95 percent light blocking. Second, install outside mount with at least one inch overlap on each side of the window frame. Third, add light-blocking side tracks to seal the gaps between the shade and the window frame. This combination blocks 99 percent of incoming light.
Are cellular shades better than blackout curtains?
Cellular shades offer better insulation due to the honeycomb air pockets, easier operation with cordless lift systems, and a cleaner aesthetic than floor-length curtains. Blackout curtains can block slightly more light when properly installed with wrap-around brackets. For most bedrooms, cellular shades are the better all-around choice, especially for window insulation.
Can I install blackout cellular shades without drilling?
Yes, several brands including LazBlinds, Tonature, Boolegon, BERISSA, and Joydeco offer no-drill tension-mounted shades that install in 30 to 60 seconds without tools. These are ideal for renters or anyone who wants a damage-free install. The shade holds in place through pressure against the window frame and removes cleanly when needed.
Final Verdict on the Best Blackout Cellular Shades for Bedrooms
After testing twelve different blackout cellular shades for bedrooms over the past year, our team keeps coming back to the LazBlinds Cordless No-Drill as the editor’s choice for most buyers. The 30-second install, real blackout performance, and child-safe cordless operation hit the right balance of price, quality, and ease of use.
If your bedroom has a unique size or you want the most flexibility, Boolegon’s top down bottom up design is the best value pick. For the absolute lowest price and a compact size, the smaller LazBlinds No-Drill is our budget pick. Whichever you choose, the right blackout cellular shades will transform your bedroom into the dark, quiet, energy-efficient retreat you have been chasing.
Sleep well, and good luck with the install. If you end up wanting smart home control for your shades later, our motorized shade controllers guide can help you retrofit the experience without replacing the shades you just bought.
