## Description

desertcart.com: BlissTrends Thick Seat Cushion for Office Chair & Car Seat, XL, LightGrey | Memory Foam with Removable Cover, Ergonomic Tailbone & Sciatica Support for Pressure Relief and Long Sitting, 3.9" Thick : Baby

Review: Nicely shaped, comfortable, just the right height. - Good quality, comfortable. Fits nicely into several different chairs that I have. Well made, holds shape firmly yet still very comfortable. It's a perfect heught. It keeps me from slouching and relieves back pain caused ny hours of sitting at the desk. I move it when I change my seating, so it's very portable. There's no fasteners or anything... just pick it up and plop it down wherever you need it. I'm quite happy with this. I've had it for quite awhile and it's still as firm as the day I bought it. It didn't flatten down over time like some that I've had on the post.
Review: Comfortable and Gives My Office Chair a Second Life - **Comfortable and Gives My Office Chair a Second Life** I’ve been using this cushion on my office chair and like it so far. It adds enough support and comfort that I can keep using my current chair instead of replacing it right now. It feels comfortable for longer periods of sitting, and so far it has been a worthwhile upgrade. The real test will be how well the foam and shape hold up over time, so I’ll see how it does with continued use. I may also try it in my vehicle on longer trips since it seems like it could make extended driving more comfortable.

### ⭐⭐⭐⭐ thick, firm, supportive cushion, well made
*by K***P on July 12, 2026*

If you’re looking for a supportive cushion this is perfect for you. I would definitely recommend it. It is very thick but NOT soft. I’d say it’s a medium density. I need a soft cushion. This will not ease my post surgery hip pain at all. I will use it for a long time, but still searching for absolutely soft cushiony for right now.
