So comfortable!
My kid's office chair seat was starting to rip and wear, so I was looking for a new seat cushion (versus buying another chair) and stumbled across this product. I was intrigued by the simple design, that it was flexible, and looked like it would fit appropriately on the chair. The cushion itself is described as a gel cushion in the product details, but it's more like silicone waffling versus a gel feel. The double-sided design is key to provide sturdy, ample joint offloading and comfort. It would be easily cleaned if something spilled on it. The cushion comes with 2 cushion covers, with texturing on one side to limit slipping. Depending on the surface, some slippage may still occur, but for the most part, it does stay in place. It is not as thick as my prior foam cushion, allowing for better posture without lowering the chair height and having to readjust my workspace. I kept this cushion for myself! I can see this being used in a wide variety of scenarios, especially if someone has hip/back pain with sitting or sits for a long time and needs extra cushion. The price is affordable too. I am very pleased with this purchase.

Finally
I recently purchased the Thickened Big Gel Seat Cushion, and it has been a total game-changer for my daily comfort and back health. This cushion delivers on its promise of strong support and relief from sciatica and back pain. The gel design is not only incredibly supportive but also breathable, ensuring I stay cool even during long periods of sitting. Whether I'm working at my desk, driving, or spending time in my wheelchair, this cushion adapts perfectly. The non-slip covers are a fantastic bonus—they keep the cushion securely in place and are easy to clean. What really impressed me was the thoughtful construction. The cushion is thick and durable, yet it feels soft and comfortable. It’s large enough to accommodate different seating surfaces without feeling bulky. If you're someone who spends a lot of time sitting or struggles with back discomfort, this seat cushion is a must-have. It’s worth every penny for the comfort and relief it provides! Highly recommend!

Does the job for my chair, medium firm, not cushy.
Not quite as cushy as it looks, but does soften the near rock hard seat of my 2021 Secret Labs Titan Evo chair enough that my gaming and work sessions can go about double the time now without serious discomfort. A definite improvement. I'd call it medium firm. If you're looking for cushy, this isn't it. It is a low enough profile that I had to make only minimal adjustments of the chair's lumbar support and arms to accommodate it.

Perfect fit for our office chair
Great replacement for memory foam seat cushion on an office chair. I've been using a memory foam cushion for a year now, but memory foam can feel a little warm, as it's really insulating... so I went looking for something better. This cushion fits the bill in several ways. First, it's well ventilated (it's got lots of holes throughout, as well as a thin, breathable cover - two covers actually! Nice touch. The black one matches our chair perfectly, but it's great to have a backup for other uses, or if this one should wear out or get damaged). Second, It's square, and the perfect size for our office chair! It's much better than the rounded memory foam one we have been using (shown in the third picture, it always shifts and needs to be re-positioned). The first picture shows it right side up, nicely sized and comfortable (there are plenty of other reviews for the pictures of the well ventilated cushion that's enclosed inside the cover). I included pictures of the cushion in our chair to show how perfectly the square shape fits. The second picture shows the bottom side up. The little pattern is grippy stuff to help keep the cushion in place, so it doesn't slide around. To sum it up: It's square - perfect shape for me; it's ventilated and cooler; it's very comfortable; and being made of gel material, it'll probably last longer than memory foam, which is likely to get crumbly with time. (At least that's what I've found with other memory foam cushions.) Overall, I recommend it.

Only the interior gel slab is purple
Well. Not what I expected so will have to make do. The issue is I kept seeing perfect and thought the seat cushion would be purple - to match my chair - but instead the gel cushion is purple and the seat covers that come with are solid black or black and gray, no purple option at all. Otherwise it's okay. Just not what I thought I was ordering.
