Review: A Game-Changer for Long Hours at the Desk – Supportive, Comfortable, and Travel-Friendly - After trying several seat cushions that flattened out or shifted around, the Xtreme Comforts Memory Foam Coccyx Seat Cushion finally delivered on what it promised. I work from home full-time and sit for long stretches, and this cushion has noticeably improved my posture and reduced the pressure on my lower back and tailbone. The U-shaped ergonomic design really does relieve that “numbness” that creeps in after hours of sitting. The memory foam holds its shape well—it feels firm but comfortable, offering real support without collapsing like cheap alternatives. I also appreciate the non-slip bottom, which keeps it in place even on slick office chairs. Bonus points for the carrying handle and storage bag—I’ve taken this cushion on a few long drives and it works just as well in the car or on bleachers. It’s a versatile option if you travel often or want something you can move between office, car, and home. If you're someone dealing with sciatica, tailbone pain, or just general discomfort from sitting too long, this cushion is absolutely worth the investment Review: Almost perfect for Nascar race. - This was the 2nd most appreciated thing I brought with me to my first (and probably last) Nascar race. I had no idea how long I would be stuck in that seat watching cars drive around in circles... or not. I can't imagine how miserable I would have been without this. I felt so sorry for the people with nothing, or just a thin flat cushion. Approaching bag check I stuck the carry bag in my tote and carried the cushions by their handles so they would not put me over the bag limit. The racetrack allowed a 14" soft cooler and a 17" backpack or tote but also allowed a soft seat cushion if it was not bagged. After passing through the check in I unfolded the carry bag and squished both cushions back into the same one again. It was a tight fit but they are foam so it worked and still even zipped closed. In addition to making our hard plastic seats much more comfortable we also used these to sit on the concrete floor while hiding from the rain and lightning. I bought these as part of the very good advice I received on things that I absolutely HAD TO BUY if I was going to a race. The #1 item was the ear muff style gun range hearing protection that kept me from going deaf. I can imagine using these in the future for several events. The only 2 things I wish they had done better: Make the carry bag waterproof. Have a waterproof backing on the bottom of the cushion. As they are they have to be protected from the rain and you have to make sure you dry wet surfaces. This foam will absorb water and nothing included protects from that. An easy though somewhat awkward fix is to put the cushion inside your rain poncho and give yourself enough slack to adjust comfortably after sitting on it. You just have to remember to grab the cushion before standing up. ## Features - [Comfort That Lasts] This car seat cushion adapts to your body to help relieve back and posterior discomfort, certified for quality and safety with OEKO-TEX and CertiPUR-US, and also works as a supportive seat cushion for office chairs - [Versatile Support] Whether used as a desk chair cushion, back support for office chair, car seat cushions for driving, or supportive wheelchair cushions, it offer lasting comfort, support, and provide a versatile solution for home and travel - [Great Posture Support] Promote better posture and ease long sitting sessions with this memory foam seat cushion for car that doubles as a coccyx cushion for tailbone pain relief cushion supporting your spine and improve your sitting experience - [Durable & Resilient Design] Built with good quality memory foam, this butt pillows for sitting tailbone maintains firmness over time, while also serving as a reliable chair cushion for back pain keeping its shape through daily use - [Convenient Cleaning] This office chair cushion for butt comes with a black mesh cover that isn't all looks, it's breathable & machine washable too, remove the zippered cover & toss it in the wash for an easy clean sciatica pain relief pillow ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01IM5CFZM | | Age Range Description | Adult | | Best Sellers Rank | #53,080 in Office Products ( See Top 100 in Office Products ) #272 in Back Cushions & Seat Cushions | | Brand | Xtreme Comforts | | Brand Name | Xtreme Comforts | | Coin Variety 1 | Back Support Pillow,Lumbar Support,Seat Cushion | | Color | Black | | Customer Reviews | 4.4 out of 5 stars 4,856 Reviews | | Fabric Type | Breathable Mesh | | Fill Material | Memory Foam | | Item Dimensions L x W | 17.9"L x 14"W | | Item Firmness Description | Firm | | Item Weight | 2.1 Pounds | | Manufacturer | Xtreme Comforts | | Manufacturer Part Number | Seat Cushion | | Material Features | Breathable | | Material Type | Premium and travel bag | | Number of Pieces | 1 | | Pattern | Solid | | Product Care Instructions | Machine Wash | | Recommended Uses For Product | Car | | Shape | Semicircular | | Size | 18X14X3 inch | | Special Feature | Portable, Washable | | Special Features | Portable, Washable | | Specific Uses For Product | Sitting, Traveling | | Target Use Body Part | Back, Legs | | UPC | 600209789395 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Xtreme Comforts - **Color:** Black - **Fill Material:** Memory Foam - **Size:** 18X14X3 inch - **Special Feature:** Portable, Washable ## Images ![Xtreme Comforts Seat Cushions | Office Chair Cushions for Desk, Car, Wheelchair| Ergonomic Memory Foam Seat Cushion for Support & Comfort | Helps Improve Sitting Posture for Work & Body Relief - Image 1](https://m.media-amazon.com/images/I/71ltz-AdkfL.jpg) ![Xtreme Comforts Seat Cushions | Office Chair Cushions for Desk, Car, Wheelchair| Ergonomic Memory Foam Seat Cushion for Support & Comfort | Helps Improve Sitting Posture for Work & Body Relief - Image 2](https://m.media-amazon.com/images/I/91NLUd5hlaL.jpg) ![Xtreme Comforts Seat Cushions | Office Chair Cushions for Desk, Car, Wheelchair| Ergonomic Memory Foam Seat Cushion for Support & Comfort | Helps Improve Sitting Posture for Work & Body Relief - Image 3](https://m.media-amazon.com/images/I/91mFXTkiYaL.jpg) ![Xtreme Comforts Seat Cushions | Office Chair Cushions for Desk, Car, Wheelchair| Ergonomic Memory Foam Seat Cushion for Support & Comfort | Helps Improve Sitting Posture for Work & Body Relief - Image 4](https://m.media-amazon.com/images/I/81Y9jDyP6OL.jpg) ![Xtreme Comforts Seat Cushions | Office Chair Cushions for Desk, Car, Wheelchair| Ergonomic Memory Foam Seat Cushion for Support & Comfort | Helps Improve Sitting Posture for Work & Body Relief - Image 5](https://m.media-amazon.com/images/I/81BPckHjPJL.jpg) ## Available Options This product comes in different **Team** options. ## Questions & Answers **Q: does this design comfortable for man to sit ?** A: As a 60 year old, 160 lbs. man with a history of back problems, I find it very comfortable. Worth the price (for me at least). **Q: Is this regular foam or memory foam?** A: This is not memory foam. This is more comfortable than memory foam which can be hot, too firm or too giving depending on the quality or type. I'm 180 lbs and suffer from sciatic type butt pain. I use this cushion over slightly padded table and office chairs. I've had my cushion for over a year and it has not flattened out or become indented. It's held up great and is large enough to cover the chair seats. **Q: 2 cushions for coccyx bone comfort r 2 firm; am only 100 lbs (not much pressure) want cushion w/ some give so sore skin heels - is this the right one?** A: No, this isn't the right one for you. It's a nicely constructed cushion, but I returned it after a week - much too firm with no give; raised me in my chair by 3 inches (I'm a 165 lbs male). Instead I ordered an EVA Medical Sloping Coccyx Cushion, Sold by Med Shop and Beyond. I've been using it for a couple weeks - it's much better; less firm, more comfortable, and still protective of the coccyx. **Q: my old cushion iis 18 x 20 will this fit large seat cushion with carry handle and anti slip bottom gives relief from back pain xtreme comforts** A: It is large and will fit. But I found it mushy w no alot of comfort as the cushion needs to be firmer and you slide toward on it w the design ## Customer Reviews ### ⭐⭐⭐⭐⭐ A Game-Changer for Long Hours at the Desk – Supportive, Comfortable, and Travel-Friendly *by D***T on July 22, 2025* After trying several seat cushions that flattened out or shifted around, the Xtreme Comforts Memory Foam Coccyx Seat Cushion finally delivered on what it promised.

The cushion itself works just fine and is supportive. My criticism comes for the value for the money, as I paid over $30 for this item, I would say the investment in cost seemed to be more for the elaborate design than overall functionality of the item as the fabric is beginning to pill and the functionality of the item is basic. I did not have a giant blue handprint design on my cushion, simply a raised, sewn in design as pictured, however the "look" of the item was not why I purchased this. The back has a simple clasp and is slightly stretchy, but overall I feel I over-paid for this even if it works, estimating the cost to be more a greater value if there were more functional elements to the cushion. Overall point: Works fine ( not a miracle worker), supports but could probably find a comparable one for less money, Average quality of outer material, Decent-quality cushion comfort. Wouldn't re-purchase. ## Frequently Bought Together - Xtreme Comforts Seat Cushion, Office Chair Cushions - Pack of 1 Padded Foam Cushion w/Handle for Desk, Wheelchair & Car Use - Back Support Pillow for Chair - Travel Bag Included - Cushion Lab Patented Pressure Relief Seat Cushion for Long Sitting Hours on Office & Home Chair - Extra-Dense Memory Foam for Soft Support.
