The cushion is shaped to take load off the tailbone, spread pressure across the seat, and do it without lifting you higher off the chair.
The U-shaped rear cutout suspends your tailbone over open space, so your sit bones carry your weight instead of the sensitive coccyx.
The contoured top follows the shape of your sit bones, spreading body weight across a wider area rather than concentrating it on one hot spot.
A low-profile shape adds support without raising your seat height — your feet stay flat and your desk setup stays the same.
Dimensions and materials, exactly as shipped.
A cushion is only worth it if it still feels like one after a few months of daily sitting. This one is built to keep its contour instead of compressing into a pancake.
6-month no-flatten guarantee — keeps its shape or your money back
Foam density
1.8–2.0 lb/ft³ high-density memory foam
Higher-density foam resists bottoming out, so the cushion keeps spreading pressure the way it did on day one.
A grippy bottom keeps the cushion where you put it — so it works across the chairs you actually sit in, not just one.
Stays put on an office chair through long workdays, no constant readjusting.
Holds position on the driver's seat for commutes and longer drives.
Grips a gaming chair so it doesn't shift during long sessions.

We'd rather you buy the right thing than the most expensive thing. A few cases where this might not be your best match:
That extra height is great for most setups, but worth checking against a low desk so your forearms still rest comfortably.
The cushion improves how you sit, not how your back is supported. It isn’t a substitute for a chair with a supportive backrest.
Still not sure? With 60-day money-back guarantee — we pay return shipping, there's no risk in trying it at your own desk — if it doesn't fit your setup, send it back.

I work from a wooden kitchen chair and it was punishing by midday. This cushion transformed it. The foam is firm enough that I do not bottom out, and the coccyx cutout takes the pressure off my tailbone completely.
The memory foam holds its shape all day and my sit-bones no longer ache. Coccyx cutout works as promised. Only minor thing is the cover picks up lint and pet hair easily, but it zips off to wash.
After a fall last year sitting was agony. The cutout at the back means there is zero pressure on my tailbone now. The foam is supportive without being too soft. I take it between my desk and car.
I had a gel-foam cushion before that went flat in a month. This one springs back every time and still feels like new after months of daily eight-hour use. The non-slip base keeps it from sliding on my chair.
I sit two hours a day on trains and this cushion has made it bearable. It contours to me, stays cool enough, and the handle makes it easy to carry. My lower back and tailbone both feel better.
Firm, supportive, and the cutout genuinely relieves tailbone pressure during long sits. I would have liked a slightly larger surface for wider chairs, but the comfort itself is excellent for the price.
I fractured my coccyx a few years ago and sitting through an 8-hour workday was miserable. The cutout actually takes all the pressure off that spot. Four weeks in and I haven't shifted or stood up every 20 minutes like I used to. The non-slip base is solid — it has not moved once on my mesh chair.
J'ai chuté sur mon coccyx il y a trois mois et m'asseoir était devenu très inconfortable. Ce coussin a changé ma vie au bureau — la découpe soulage vraiment la pression sur la zone. La mousse haute densité ne s'est pas écrasée en plusieurs semaines d'utilisation quotidienne. Je ne m'en sépare plus.
I do a 90-minute commute each way on hard plastic seats and my hips were always aching by the time I got to the office. This cushion fits easily in my bag thanks to the handle and transforms any seat instantly. The foam still feels the same as day one after about six weeks of daily use. Genuinely happy with it.
I'm quite petite and this cushion works really well for me — plenty of support without being too high. My husband tried it and found it a bit soft for his build. The coccyx cutout is well designed and the cover is genuinely machine washable without shrinking or warping. A firmer variant would make this perfect for larger users.
