The Everlasting Comfort Doctor Recommended Memory Foam Seat Cushion is worth buying if eight hours in a desk chair leaves your tailbone sore. The U-shaped cutout means your tailbone never touches the seat, and the foam rebounds instead of packing flat. Buy it for office chairs, car seats, and long travel days.

How this review was made: written from my own video review of this product. Every opinion here is my own, from using it myself.
Quick Verdict
You see that gap? Your tailbone’s gonna float. Press the foam and it comes right back, which is the difference between real memory foam and the flat pancake you get from cheap filler. Stop suffering through another afternoon with a numb butt.
Buy if you:
- Sit eight hours a day and start squirming by lunch
- Have tailbone or coccyx pain and need zero contact back there
- Drive long routes or commute and want the same cushion in the car
- Need something washable because it lives under you all day
Skip if you:
- Have a low desk, because this adds height and your knees will come up
- Want lumbar support, this is a seat cushion only
- Need a cooling gel layer, this is 100 percent memory foam

Your Tailbone Isn’t Supposed To Carry You
Sitting on your tailbone for eight hours, no wonder you’re squirming by lunch. That’s the whole problem a flat chair creates. Your weight funnels into the one bony point that was never built to take it, and by 2pm your body starts hunting for a new position every ninety seconds. The Everlasting Comfort Doctor Recommended Memory Foam Seat Cushion takes that contact away entirely. You see that gap? Your tailbone’s gonna float.
As an OT, positioning is half the battle right there. Hips level, spine stacked. The cushion does that part for you.
Unbox It, Sit On It, Done
There’s no setup. You pull it out, drop it on the chair with the U-cutout facing the back, and sit. The non-slip bottom keeps it from sliding forward when you scoot in, which matters more than it sounds like it would, because a cushion that creeps is a cushion you stop using.
Give compressed memory foam an hour or so out of the shipping bag before you judge it. Foam that has been vacuum-packed sits firmer than it will on day three. The rebound is the tell. Press it and watch, the foam comes right back. That’s real memory foam.
Does memory foam go flat over time?
Cheap seat cushions flatten within months; this one is 100 percent memory foam rather than foam chips or a thin layer glued over polyfill. This one is 100 percent memory foam rather than foam chips or a thin layer glued over polyfill, and that single construction detail is what decides whether a seat cushion is still working in month eight or has turned into a sad pancake under your weight.
Here’s the simple test, and you can do it at home on any cushion you already own. Press your thumb in hard, let go, and count. Real memory foam fills the dent back in on its own. Filler foam holds the dent. That’s the entire difference between a cushion that keeps your pelvis at the right angle for a year and one that lets you sink right back onto the tailbone you were trying to protect.
Volume backs this up too. Amazon reports more than 10,000 of these sold in the past month, and it’s sitting at #122 in Office Products. A return rate problem doesn’t put you at #122 in Office Products with 10,000 monthly sales, that ranking is sustained, not a spike.

The cover is machine washable, and that’s the maintenance plan in full. No consumables, no replacement parts, no app. Strip it, wash it, let it dry, put it back. The foam core itself never goes in water.
If it’s living in a car, wash it more often than you think. Breathable fabric plus a warm seat plus a daily commute adds up.
The Height Trade-Off Most Reviewers Skip
A seat cushion raises you, and that changes your whole desk setup. Add a couple inches under you and suddenly your knees sit higher than your hips, your forearms angle up at the keyboard, and your shoulders creep toward your ears. You fixed the tailbone and broke the elbows.
The fix is free: drop your chair height to compensate. If your chair is already at its lowest, or you’re in a fixed-height dining chair at the desk, that’s a real limitation and you should know about it before the box shows up.
It’s Not Padding, It’s Geometry
Softness is the wrong thing to shop for here. What this cushion actually does is tilt your pelvis forward just enough to spread your weight across your sit bones, the two bony points built to take it, instead of letting it funnel down onto the tailbone that wasn’t.
Which is why the U-cutout matters more than the thickness. Softer isn’t better here. A cushion that just swallows you keeps the tailbone loaded, only now you’re sunk into it. The cutout removes the contact altogether, and the firm rebound keeps you at the right height while it does it.
Worth Buying, But Time The Price
This solves one problem completely and doesn’t pretend to solve others. Tailbone contact goes away. Lower back support, cooling, lumbar curve, none of that is in here, and if that’s what you came for you want a different product. What you get is a firm memory foam wedge with a cutout, a washable cover, and a non-slip base that moves between your office chair and your car without any fuss.
One buying note from the data I track: the price on this one moves around a lot. The price moves more than you’d expect for a sub-$40 cushion, I’ve seen it swing by roughly a third depending on the day. So check the live price rather than assuming, and if you’re not in a rush it’s worth a second look later.
Pros
- U-shaped cutout removes tailbone contact entirely, no floating pressure point
- Foam rebounds immediately instead of staying compressed
- Machine-washable cover with a non-slip bottom that stays put
- Moves between office chair, car seat, wheelchair, and airplane seat
- Zero setup, no assembly, no accessories to buy
Cons
- Adds seat height, so a desk that’s already low becomes a problem
- No lumbar or back support of any kind
- No cooling gel layer, it’s straight memory foam
- Price swings a lot, so buying on the wrong day costs you
Frequently Asked Questions
Will it work on an airplane seat?
Yes, airplane seats are listed as an intended use alongside stadium benches and truck seats. It’s a Large, so on a tight economy seat it’ll fill the width. Pack it as a carry-on item rather than trying to squeeze it into a bag.
Can it be used after surgery or in a wheelchair?
It’s marketed for wheelchair use and post-surgery pressure relief, and the cutout design is the right idea for both. That said, if you’re recovering from a procedure or managing a pressure injury risk, ask your own clinician first. A general-purpose cushion is not the same as a prescribed pressure-redistribution surface.
Does it need to be washed a certain way?
The cover is machine washable, the foam is not. Unzip and remove the cover before washing, and air dry it rather than running it hot, since heat is what shrinks fitted covers and makes them a fight to get back on.
Is it the same as a gel seat cushion?
No. This is 100 percent memory foam, so it conforms to your shape and holds that support. Gel cushions trade some of that contouring for a cooler surface. If you run hot in your chair all day, that’s the comparison worth making before you buy.
