## Description

desertcart.com : TushGuard Seat Cushion, Memory Foam Office Chair Cushion - Black, Large | for Car Seat, Airplane, Desk Chair - Sciatica & Hip & Coccyx Pain Relief Cushion for Long Sitting Office Workers, Car Drivers : Office Products

Review: Really good Cushion. - This TushGaurd Cushion is Great. I ordered the Large in Grey to match my truck. So far after a weeks of daily use it is good to go. Definitely does the job as advertised. It is comfortable. Versatile. Easy to move around if need be. Ordered a few more for the other vehicles I have. Farthest trip so far has only been about 30-45 mins and it seemed good. You do feel a bit taller in the Car Seat sitting in this so you will have to adjust your seat height. My back and hip have pain relief now using this. So far so good. Highly recommend.
Review: Just buy it, you found what you're looking for - Just buy it! You won't regret it. If you've ever sat on a chair for more than a couple of hours and have to hobble away after, yes, this is what you're looking for. September 2022 I purchased this and it's now July 2026 and it still saves my back daily. I have used this pillow nearly every single day, at minimum 5 days a week for 8+ hours. Doing extremely rough match I've spent about 7,000+ hours sitting on this pillow and it works the same as the day I purchased it. The thickness of the pad is perfect, you don't feel like you're sinking and you don't feel like you're sitting on a hard floor. It's perfectly supportive in the way that you forget about it because it works so well, but if you remove it you see an immediate change. I use it in a standard desk chair and it fits fine. I am a larger woman with wide hips and I don't spill over the sides. I do like the cooling quality to it in the summer and I simply drape a blanket over my chair in the winter to make it cozy and warm. I would buy this again (though it's such high quality I have no doubt it will last for years to come) and I reccomend it to my friends and family all the time. As a bonus above everything else, there's a nice handle where you can carry it to your office and I use it in my craft room while sewing. And if somehow you're still not convinced, this pillow is easily a half to a quarter the price of similar ones and it is a workhorse.

## Questions & Answers

**Q: I am looking for something that will also help provide a little "boost" to my chair at work as am I a very short man, will this add height?**
A: Agree with others. Not a lot of height. Mine compresses quite a bit but does feel like I’m boosted ever so slightly. Not enough to make a huge difference. I am a big guy though so a lighter person may get a little more height out of it

**Q: This one is okay, but not great. It compresses a lot when you sit on it. Do you make one that is thicker and/or more firm?**
A: Dear customer, sorry the seat cushion cannot meet your expectation.  The seat cushion is made of 100% pure memory foam, the thickness is 3.15 inches.  As it is a new product, we will continue to improve it and make much thicker.

**Q: Is this chair pad suitable for heavy people?**
A: I’m a big guy, 6”6’ and 265lb and it has help my tailbone pain quite a bit. It does compress considerably but seems to offer just enough cushion that it helps. Always bounces back to shape when I get up too

**Q: What is the size of this seat cushion?**
A: This cushion measures 18.11''x14.17''x3.15'' in length, width and height. Wait 10 seconds after unpacking and the cushion will rebound back to this size.

### ⭐⭐⭐⭐ Noticeably More Comfortable for Long Sitting
*by S***H on August 27, 2026*

I’ve been using this cushion on my office chair during longer work sessions, and it has made the chair much more comfortable. The foam has enough support to keep me from feeling like I’m sitting directly on a hard surface, but it still has some give to it. I like that it doesn’t take up too much room and fits nicely on a standard office chair. It is almosta little too soft and I would like a firmer mould. Comfort: Soft enough for extended sitting while still supportive Fit: Works well on my existing chair without sliding around constantly Convenience: Easy to move between chairs when needed The cover is also a nice touch since it makes the cushion feel more finished and easier to maintain. It’s not a replacement for a really good office chair, but it’s an inexpensive way to make an uncomfortable one more pleasant.
