Wake Up Aligned. From Night #1

When your top leg drops across the bed, it drags your pelvis and twists your lower spine, hour after hour, all night long. That's the dull morning ache in your hips and lower back.

The Stay-Put Cushion keeps your knees stacked and your hips level, so your spine finally rests in a neutral line instead of collapsing sideways. Most people feel the difference the very first morning.

The 3am Slide

The Problem Your Knee Pillow Was Never Built to Solve.

You already know the trick, a pillow between your knees just works. The problem was never the idea. It was the pillow.

It slides. It goes flat. It ends up on the floor by 3am while you're wide awake, patting around in the dark trying to find it. So you give up, roll flat, and wake up with the same twisted hips you were trying to fix.

The fix isn't a fluffier pillow or a firmer one. It's a cushion shaped for real leg separation with a strap that keeps it exactly where you put it; through every roll, every shift, every 'just five more minutes.'

Beyond your knees

Level Hips, Happier Lower Back

Stacking your knees is really about your pelvis. When the top knee slides forward and down, it rotates your hips and puts a slow, all-night pull on your lower back and sciatic line.

Hold the knees apart and level, and that rotation disappears. Side sleepers, expecting moms, and anyone recovering from hip or back strain feel it as less pressure where it used to build up.

Not a medical device. If pain is tied to a diagnosed condition, talk to your doctor or physical therapist.

Rolls With You, Not Away From You

The Strap Does the Work

A soft, stretchy band loops your thigh once and keeps the cushion locked to your leg; so it travels with you instead of getting left behind.

Roll Left, Roll Right

Switch sides as many times as you want. The pillow comes along every time, no repositioning and no reaching under the covers.

Made for the people who need it most.

We're not another "miracle pillow."

Built because we were tired of losing ours at 3am.

We built the Stay-Put Cushion because we'd tried them all — the wedges that flatten, the memory-foam blocks that slide, the rolled-up blankets that end up on the floor. Every one of them worked great, right up until we moved.

No miracle claims. No belts, no forts, no losing it under the covers. Just the support you already believed in, finally staying where you put it; backed by a guarantee so trying it costs you nothing.

The Search Ends Here.

Contoured memory foam sized for real leg separation, a breathable machine-washable cover, and a soft elastic strap that holds all night. It's the reliable, alignment-keeping staple your side of the bed has been missing.

14Night sleep-on-it guarantee
If you hate it, return it!

"Sleep On It" Guarantee

Sleep with the Stay-Put Cushion for a full 14 nights. If it slides, flattens, or your hips don't feel better, if it's not the one that finally ends the trial-and-error, send it back. No "return nightmare." You've already lost enough sleep chasing this fix. This is the one purchase where the risk is on us, not you.

Frequently Asked Questions

Everything worth knowing before night one.

Real answers about the strap, the foam, the fit, and the 14-night guarantee.

I've tried knee pillows before and they all slid off. Why is this different?

Because none of them strapped on. The Stay-Put Cushion has a soft elastic band that loops your thigh and keeps the pillow locked to your leg through every roll. It moves with you instead of getting left behind, that's the entire reason we built it.

Will the strap feel tight or uncomfortable?

No. It's a wide, stretchy band that rests loosely around your thigh, enough to hold the cushion, not enough to pinch or cut off circulation. Most people forget it's there within a minute.

Does the memory foam get hot or go flat?

It's high-density, breathable memory foam with a cool-touch cover, so it won't overheat or collapse into a thin wedge like budget pillows. It holds its contour and support for 8+ hours, night after night.

Can I wash it?

Yes. The cover zips off and is machine-washable, so it stays fresh. The foam core keeps its shape underneath.

What if it doesn't work for me?

Sleep with it for 14 nights. If it slides, flattens, or just isn't the one, send it back for your money back. The only risk is one more night with a pillow on the floor.
