Is this the right product for me?

Built for one job: closing the gap at the head of your bed.

It's for you if you want to:

  • Wake up with your pillow still under your head
  • Stop fishing pillows out from behind the headboard
  • Keep the frame and mattress you already own
  • Cover both sides of a shared bed with one piece
  • Keep your phone and glasses on the bed

Not the right fit for:

A baby's sleep space or a crib. Nothing soft belongs where a baby sleeps.

Murphy beds with a 10 to 12 inch gap, or adjustable bases that move.

Leaning back to sit up. At 6 inches tall it fills the gap but is not a backrest.

Will it fall in too?

No. It sits on top of the mattress, not in the gap. It is wider than the gap, and the grip dots hold it in place. Its tall side rests against the headboard, so there is nothing to tuck in.

Will it fit my gap?

Yes, if your gap is a few inches wide. To check, push the mattress against the headboard and measure the gap at its widest point. Then pick the size that matches your bed.

Is this the right fit for me?

Yes, if you deal with any of this:

  • Your pillow slips into the gap behind your bed
  • You fish your phone out from behind the headboard
  • You drag the bed out to get things back
  • Your child's leg slips into the gap at night

This wedge fills the gap between your mattress and headboard, so nothing can fall through. It has a pocket on each side, so your phone and remote stay within reach.

Materials & care
  • Foam: high density 25D foam. It springs back instead of going flat.
  • Cover: breathable 260gsm fabric
  • Base: silicone grip dots that stop it sliding
  • Pocket: one on each side for your phone, remote or glasses
  • Washing: machine wash the cover. Wipe the foam clean and let it air dry. Don't put the foam in water.
  • First use: give it 12 to 24 hours to expand fully after you unpack it
  • Size: 39 x 10, 54 x 10, 60 x 10 or 76 x 10 inches

AS FEATURED IN

THEY DOUBTED IT TOO

It sits on top of the bed, not in the gap itself. Initially I thought it was a dumb design, but it actually works very well.

A couple with a bed gap

WHAT CHANGES

Both of You Sleep Through the Night

You'll notice it the first morning.

Wake Up on Your Pillow

Your head is on it, not the bare mattress.

No Pillow Hunts at Night

Nobody reaches behind the bed in the dark.

Nothing to Reset

Fill the gap once. No more pushing the mattress back.

A Bed That Looks Finished

It looks like bedding, not a lump.

One piece covers both sides of the bed.

WHY IT HAPPENS

It's Not Your Pillow. It's the Gap Behind It.

Side view: on a flat seat the tailbone presses down; on the donut it sits over open space
Pillows slide down the gapWedge on top, pillows stay up

Your mattress sits a few inches short of the headboard. At night your pillow slides back and drops in.

Why the usual fixes don't help

  • Pushing the mattress back lasts about half a night
  • Rolled blankets and pool noodles squash down or fall through
  • A new headboard costs far more and may leave the gap open

The fix: close the gap from on top

This wedge sits on the mattress, wider than the gap, so there is nothing left to fall into. Your pillow rests against it all night.

HOW IT WORKS

Why the Grip-Dot Gap Wedge Stays Put

The donut cushion from above12345
  1. Grip-dot base

    Silicone dots hold it on the mattress, so it stays at the head all night.

  2. Wider than the gap

    It bridges the gap from on top, so it never drops in the way a rolled blanket does.

  3. Tall side at the headboard

    The 6 inch side rests against the headboard or wall and closes the gap.

  4. Medium firm foam

    Firm enough not to squash into the gap, soft where your head touches it.

  5. Zip-off knit cover

    Unzips for the washing machine and looks like a plain sheet in White or Gray.

YOUR QUESTIONS

Still Not Sure?

Will it feel hard against my head?

No, it's medium firm.

  • Soft enough for your head to rest against
  • Firm enough that it does not squash into the gap

It fills the gap. At 6 inches it is not a backrest.

Will my partner mind it in the bed?

No, it sits behind your pillows.

  • It rests at the headboard, out of the way
  • You both stop losing pillows, so nobody reaches into the gap
Will it get greasy and hard to clean?

No, the cover zips off.

  • Machine wash the cover cold on gentle, then air dry
  • Wipe the foam core clean and never soak it
Can my dog still sleep up by our heads?

Yes.

  • Your dog can curl up by your heads
  • Your pillows stay put while your dog settles in

For comfort only. It is not a safety barrier.

Will it stay flat out of the box?

No, it rises to its full 6 inches.

  • It ships vacuum packed to save space
  • Allow 12 to 24 hours, up to 48 hours in a cold room

Tip: unpack it the day it arrives.

Complete your setup

You Hear It Slide. Then You Hear It Land.

It's late, the light is off, and your phone has just gone down the back of the bed.

Now you're kneeling on the mattress with one arm in the dark, feeling around between the headboard and the wall.

Last night it was your book. The night before, your glasses.

A Small Gap, Every Single Night

It never feels like a real problem. It just never stops.

2 A.M.

Your Pillow Slips Away

You wake with your head on the bare mattress. Your pillow is halfway down the gap, and you drag it back half asleep.

THE MORNING

Everything Is Down There

The remote, a hair tie, the charger. You can see some of it. Getting it back means moving the bed, so it stays there until the weekend.

EVERY WEEK

You Shove the Mattress Back

You push it hard against the headboard and feel sorted. A few nights of turning over, and it has crept away again.

What you've told yourself
  • “It's only a small gap.”
  • “I'll push the mattress back again.”
  • “Every bed does this.”

You're Not Careless. The Gap Is Always Open.

You don't drop things more than anyone else. Whatever rests near an open gap ends up in it sooner or later.

All that's missing is something solid sitting in that space, so your pillow has a wall behind it and your phone has nowhere to go.

Closing that gap is the one thing this wedge is here to do.

Your Phone Just Slid Behind The Bed

It's late. You put your phone down by your pillow, and a second later you hear it drop behind the headboard. Now you're on your knees in the dark with your arm in the gap. Books go the same way, and so does your pillow. This foam wedge fills the space between your mattress and headboard, so there's nowhere for anything to fall.

Stuffing A Blanket In The Gap Won't Last

You've probably pushed a rolled blanket or a spare pillow in there. It holds for a night, then it sinks or works loose and the gap is back. This wedge is high density foam, so it keeps its height. The underside is covered in silicone grip dots that hold it in place while you move around in your sleep.

Everything You Reach For Stays Close

Glasses, the remote, the book you're halfway through. They used to live on the floor or on a crowded nightstand. There's a pocket on each side of the wedge, right where your hand lands. The breathable fabric cover comes off and goes in the washing machine. Give the foam 12 to 24 hours to expand when you first unpack it.

Frequently Asked Questions

Who is it for?

Anyone with a gap between the mattress and the headboard. The wedge fills it, so pillows, phones and glasses stop falling behind the bed.

If your mattress already sits tight to the headboard, you don't need it.

If your bed base raises and lowers at the head, a foam wedge may get in the way.

Which size do I need?

Match the length to the width of your mattress. It comes in 39, 54, 60 and 76 inch lengths.

Measure across the head of your bed before you order.

Give it 12 to 24 hours to expand fully after you unpack it.

Will it stay in place?

The underside has silicone grip dots. They hold the wedge where you put it through the night.

The high density foam springs back, so it keeps filling the gap.

You may still need to straighten it when you change the sheets.

How do I wash it?

The cover is machine washable. Wipe the foam clean and let it air dry.

Don't put the foam in water.

Honestly this is better than I expected. I kept seeing all tiktok videos everyone saying they love it so I had to try it. I’ve purchased 4 in total and can’t wait to gift them this year! If you haven’t tried the comforter I highly recommend that as well.

Absolutely love it! It’s big, super soft, and honestly way better than the cervical pillow I was originally planning to get. It still supports my neck, but feels much gentler and looks so much nicer too. Total upgrade!

★★★★★ Chloe N. Verified Verified Buyer

When I say I’ve bought so many pillows, this is what I mean….. And this cloud pillow turned out to be the best, yet it’s the cheapest of them all, I didn’t even believe it when I placed the order, but after a few nights sleep, it’s just perfect. I’d recommend it to anyone I know.

★★★★★ Maria T. Verified Verified Buyer

I've been a side sleeper my whole life and I've never found a pillow that didn't leave my shoulder aching by morning. The arm contour on this is a complete game-changer. No more waking up with a dead arm or a stiff neck.

I was skeptical about all the hype but figured I'd try it with the guarantee. Best decision I've made for my sleep in years. I fall asleep faster and I'm not tossing and turning all night trying to get comfortable.

★★★★★ Riley J. Verified Verified Buyer

My friend told me to try this pillow, and I’m so glad I did. I’m a light sleeper and really picky about bedding, but after using it for a month I can honestly say it’s the best one I’ve had. It stays cool all night, and the memory foam supports my neck perfectly. Definitely getting another one for my boyfriend!

★★★★★ Jordyn G. Verified Verified Buyer

I love that it stays so cold all night no matter how long you sleep on it. Incredible if you’re a hot sleeper! It also helps take pressure off my neck and shoulders so I haven’t been waking up in pain like I normally would! 12/10 recommend

★★★★★ Natalie S. Verified Verified Buyer

Absolutely love this pillow. We ordered more so my bf can have one when he is in his tractor trailer. We also ordered some for our son and his partner. we also love the soft pillow cases. I may get them as Christmas gifts for my other children.
