This is fine, but no where near that level of long term sitting comfort. This isn't going to be good for a heavy set person sitting at a desk 8 hours a day, but it will be just fine for a scraggly teen upgrading their cheap after school pc chair, or grandma at the breakfast table! It makes a world of difference, but you should pair this with a lumbar support cushion for pc sitting of course. For the right person who needs it, this is a 5 star product and extremely durable. Easy to clean, holds its color without fading, well made.I give it 5 stars because it is as described, looks like the product shone, is as thick as shown (not very thick compared to expensive products, but definitely good for its thickness) and there were no defects. It has stood the test of time and makes my 110 pound teen daughter not have any discomforts sitting at her desk for 3 hours of homework and gaming- where as before she couldn't sit for longer than 45 minutes because her favorite 'spinny chair' was flat and hard, just uncomfortable. We kept the favorite chair! Woohoo! It's the little things in life, right?After months of use, it's about exactly as purchased. If you're looking for this size of cushion, this one is great. If you're looking for something life changing due to extreme pain and not just 'this chair is uncomfortable' I would pay a bit more for something thicker, and with a more pronounced gap for tail bone pressure relief. ### ⭐⭐⭐⭐⭐ Perfect fit for our office chair *by on Reviewed in the United States June 20, 2024* 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. ### ⭐⭐⭐⭐ Comfortable, but slides around *by on Reviewed in the United States July 11, 2025* The comfort of this seat cushion is quite good. I like it. However, I wish the grippy material on the cover was more grippy. I it's kind of pointless (doesn't grip at all). It's almost more slippery than grippy. ## Frequently Bought Together - Seat Cushion, Thickened Big Gel Seat Cushion, Strong Support, Sciatica & Back Pain Relief, Breathable Cool Suitable as Office Chair Cushion, Car Seat Cushion, Wheelchair Cushions, 2 Non-Slip Covers - TranquilRelax Large Seat Cushion, Soft Foam Cushion for Long Sitting Hours on Office Chair, Home & Car, Non-Slip Chair Pad for Relieving Back & Sciatica & Hip & Coccyx Pain (Black) - Memory Foam Seat Chair Cushion for Relieves Back Sciatica Pain Tailbone Pain Coccyx Degenerating Disc Orthopedic Osteoarthritis Prostate Cushion Low Back Pain Cushion Hip Shaping (Dark Gray) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.lk/products/619437100-seat-cushion-thickened-big-gel-seat-cushion-strong-support-sciatica](https://www.desertcart.lk/products/619437100-seat-cushion-thickened-big-gel-seat-cushion-strong-support-sciatica) --- *Product available on Desertcart Sri Lanka* *Store origin: LK* *Last updated: 2026-09-14*
