Sleepr Blind is a made-to-measure total-blackout system with opaque honeycomb fabric, fitted side guides and a lower seal. Enter your width and height in centimetres, choose white or black, and follow the labelled installation guide. If the finished blind does not fit, return shipping is on us; we review the measurements and help put the fit right.
The direction determines where the blind rests when the window is clear and which way it moves to close.
Width 20–300 cm; height 20–300 cm. Enter measurements to one decimal place.
Measurements are valid.

The Sleepr
Sleepr Blind
Dark fabric alone still lets light spill around the edges. Sleepr Blind combines an opaque honeycomb blind with fitted side guides and a lower seal, helping close the perimeter when it is measured and installed correctly.
MEASUREMENT GUIDE
Four simple steps to a blind that fits.
Step 01Step 1 of 4
Measure the clear depth from the front edge of the recess toward the window, then use the smallest measurement.
You need at least 3 cm of clear space.
Step 02Step 2 of 4
Check handles, locks and any parts that protrude. Measure from the front edge to the nearest obstruction.
Step 03Step 3 of 4
Measure the width at the top, middle and bottom, then the height at the left, centre and right. Always use the smallest measurement.
Measure inside the window recess.
Step 04Step 4 of 4
Keep the tape straight, measure twice and record to the nearest millimetre. Enter centimetres with one decimal place.
INSTALLATION GUIDE
Follow the guide and fit your blind without specialist tools.
Step 01Step 1 of 4
Lay the profiles on a flat surface. Join the side profiles to the top and bottom, with the inner channels facing inward and the marked ends aligned.
Check that the finished frame is square and stable.
Step 02Step 2 of 4
Peel away the backing and press the strip along all four sides. Do not stretch it; shape it neatly around each corner.
Step 03Step 3 of 4
Remove the backing and place the brush beside the sealing strip. Trim the corners so the top and bottom finish flush.
Step 04Step 4 of 4
Hold the frame at roughly 70°, set the bottom in first, then press the top into place. Check the spacing and test the blind.
No drilling or specialist installer required.
No light gaps
The fitted frame closes the gaps ordinary blinds leave behind.
Made to your measurements

The quiet work happens inside
The cellular blind traps small pockets of air between your room and the window. That structure does more than block light: it adds a considered layer of thermal and acoustic comfort.
Air pockets help slow heat moving through the window, softening temperature swings near the bed.
Layered material and an enclosed frame help take the edge off some noise reaching the glass.
Adding a barrier at the window can help your room hold onto the temperature you have created.
Dark fabric covers the glass. A made-to-measure system is designed around the whole opening.
Curtain-style or standard blind
The fabric covers the middle while daylight can still spill around the sides, top and sill.
Standard width increments can leave an awkward gap or require cutting and adjusting at home.
Darkens the room but adds little structure between the room and the glass.
Curtains or a loose blind can cover the window without giving the opening a clean fitted finish.
When a generic size is wrong, getting the window covered properly can become another DIY job.
The Sleepr
The top rail, fitted side guides and lower seal work together around the opening.
Enter the width and height to 0.1 cm for a blind made around your actual opening.
The cellular construction adds thermal and acoustic comfort at the window.
The colour-matched frame contains every edge for a streamlined part of the window.

Comfort beyond blackout
Windows are where rooms often gain and lose heat fastest. The honeycomb cells add a layer of still air at the glass, helping the bedroom feel more settled across seasons.
When it is warm outside
Closing the blind helps reduce direct light and adds another barrier between sun-warmed glass and the room.
When it is cold outside
The cellular layer helps soften the cold-window feel and slow warmth moving towards the glass.
The science of dark sleep
Independent sleep and circadian research keeps landing on the same conclusion: light during sleep — even a little — changes how your body rests and repairs. Here is what the studies actually measured.
100 lux
In a randomized PNAS study, a single night of sleeping in ordinary room light raised nighttime heart rate and measurably worsened next-morning insulin resistance (Mason, Zee et al., 2022).
5 lux
Dimmer than a streetlamp bleeding around a curtain edge — yet polysomnography showed more arousals and shallower sleep (Cho et al., 2016).
Deep sleep
Lights-on nights produced less slow-wave (deep) sleep and reduced delta and spindle power on EEG (Cho, Joo et al., 2013).
88,905
Higher night-time light exposure was linked to higher all-cause and cardiometabolic mortality in a large wearable-sensor cohort (Windred, Cain et al., 2024).
The Sleepr promise
Measuring something custom can feel like the hard part. Our guide and support are there to make the decision feel straightforward from the first centimetre.
Contact us and we cover return shipping, review the measurements and help put the fit right.
Measure in three places and enter the smallest width and height to the nearest 0.1 cm.
Labelled parts and a clear step-by-step guide help you install the blind with confidence.

It is designed as a total-blackout system: opaque honeycomb material blocks light through the blind, while the top rail, side guides and lower seal address light around the edges. Correct measuring and installation are essential for the closest seal.
We handle it. Contact us with your order number and a photo of the opening. Return shipping is on us, and we will review the measurements and help put the fit right. Following the measurement guide before ordering helps us resolve any problem quickly.
Measure the clear opening in centimetres at three points across the width and three points down the height. Enter the smallest width and smallest height to the nearest millimetre (0.1 cm). Check that the recess has at least 3 cm of clear depth and is free from handles or vents where the frame will sit.
The current configurator accepts a width and height from 20 to 300 cm. If your window falls outside those limits, contact us before ordering and we can confirm whether another solution is possible.
Sleepr Blind is available in white and black. The blind, frame and guides use a coordinated finish for a clean, built-in look. Colours may appear slightly different from screen to screen.
The cellular structure holds pockets of air between the room and the glass, adding an insulating layer that can help slow heat transfer and reduce the cold-window feel. Results depend on the window, room and installation.
The layered blind and enclosed frame can help soften some sound reaching the window, but Sleepr Blind is not a soundproofing system. Window construction and wall insulation still make the biggest difference.
Yes. The blind is supplied as a labelled system with a step-by-step guide. Read the guide before starting, check the opening is square and clear, and ask someone to help with wider blinds.
Contact info@thesleepr.com with your order number, a photo of the opening and the measurements you used. We cover return shipping, review the measurements with you and help you reach the right solution.
Use a soft duster or a vacuum on its lowest setting with a brush attachment. For marks on the frame, use a lightly damp microfibre cloth. Avoid soaking the honeycomb material or using abrasive cleaners.
