Good quality. Reasonable price. Review: Good for the price - I bought this set as I work from home and my chair at home has become hard and uncomfortable. Overall the set is really comfy, it’s not too soft and is supportive enough for those (like me) who suffer with a bad back from sitting at a desk all day. The back piece is a life saver really and probably the best part. Downsides is that I think the base cushion is a little small, as you can see in my executive style chair it doesn’t fill the base and where it is a little small I find it hard to get comfy as my personal preference is a wider base chair. That is really the only fault I can find in the product so far, so if you have a smaller base chair it would be perfect, but it’s not great for those with a larger seat. Overall the value for money is good! ## Features - 2-PIECE COMFORT: Transform any workspace with this FORTEM combo featuring matching seat cushions and supportive back pillow designed to provide long lasting comfort. The memory foam seat cushion cradles your lower body, while the matching lumbar support pillow aligns to your lower back. Together, they create a comprehensive lumbar support chair setup that is perfect for long hours sitting at your desk. - ERGONOMIC SUPPORT: A high-performance seat cushion for office chair use paired with an integrated back support for office chair frame. This 100% memory foam ergonomic seat cushion set works beautifully together to distribute your upper body weight evenly. It functions as the ultimate desk chair back support tool to stop slouching and improve physical wellness at your computer. - PREMIUM QUALITY: Engineered for intense workdays, this durable office chair cushion for long sitting keeps you focused without flattening out over hours of continuous use. The high-density memory foam seat pad retains its shape perfectly, functioning alongside a back lumbar support cushion to absorb tension. It provides the targeted lower back support for office chair setups that modern professionals truly deserve. - UNIVERSAL FIT: Equipped with adjustable straps, this versatile lumbar support for car travel stays securely positioned through long commutes. It easily transitions into an effective car seat lumbar support set to transform stiff vehicle interiors into luxury cabin seating. It is the perfect back support for car seat driver spots, keeping you comfortable no matter how long your trip is in your sedan, SUV, pickup truck or commerical vehicle. - WASHABLE COVERS: Keep your seat fresh with an office chair seat cushion and lumbar combo featuring removable zip-covers. Ensure that your office seat cushion stays fresh by washing it whenever you want. Simply zip the covers off and throw them in the washing machine to keep your premium lumbar pillow and seat cushion looking brand new. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09T3XZ51H | | Age Range Description | Adult | | Best Sellers Rank | 5,630 in Home & Kitchen ( See Top 100 in Home & Kitchen ) 15 in Back & Seat Cushions | | Brand | FORTEM | | Brand Name | FORTEM | | Coin Variety 1 | Memory Foam Pillow,Memory Foam,Seat Cushion,Lumbar Support | | Colour | Black Velour | | Country Of Origin | China | | Customer Reviews | 4.2 out of 5 stars 1,982 Reviews | | Fabric Type | Memory Foam | | Fill Material | Memory Foam | | Fill material | Memory Foam | | Item Dimensions L x W | 45.7L x 35.6W centimetres | | Item Firmness Description | Medium | | Item Shape | Semicircular | | Manufacturer | FORTEM | | Manufacturer Part Number | FRTM-SCLS-BLACK-VLR | | Material Features | Lightweight | | Material Type | Memory Foam | | Material Type Free | Latex Free | | Model Name | FRTM-SCLS-BLACK-VLR | | Model Number | FRTM-SCLS-BLACK-VLR | | Number of Pieces | 2 | | Pattern | Solid | | Product Care Instructions | Machine Wash | | Recommended Uses For Product | Office Chair | | Shape | Semicircular | | Size | L | | Special Features | Anti-Slip | | Special feature | Anti-Slip | | Specific Uses For Product | Office Chair | | Target Use Body Part | Body | | UPC | 819853025449 | | Unit Count | 1.0 count | ## Product Details - **Brand:** FORTEM - **Colour:** Black Velour - **Fill material:** Memory Foam - **Size:** L - **Special feature:** Anti-Slip ## Images ![FORTEM Coccyx Cushion, Seat Cushion, Lumbar Support Cushions, Back Support Cushions for Office Chair, Memory Foam Seat Pillow Breathable & Washable Cover, Adjustable Straps - Image 1](https://m.media-amazon.com/images/I/813h5+x6TfL.jpg) ![FORTEM Coccyx Cushion, Seat Cushion, Lumbar Support Cushions, Back Support Cushions for Office Chair, Memory Foam Seat Pillow Breathable & Washable Cover, Adjustable Straps - Image 2](https://m.media-amazon.com/images/I/81IHcgh8G3L.jpg) ![FORTEM Coccyx Cushion, Seat Cushion, Lumbar Support Cushions, Back Support Cushions for Office Chair, Memory Foam Seat Pillow Breathable & Washable Cover, Adjustable Straps - Image 3](https://m.media-amazon.com/images/I/81GBu+5JbEL.jpg) ![FORTEM Coccyx Cushion, Seat Cushion, Lumbar Support Cushions, Back Support Cushions for Office Chair, Memory Foam Seat Pillow Breathable & Washable Cover, Adjustable Straps - Image 4](https://m.media-amazon.com/images/I/81pKfFxFbnL.jpg) ![FORTEM Coccyx Cushion, Seat Cushion, Lumbar Support Cushions, Back Support Cushions for Office Chair, Memory Foam Seat Pillow Breathable & Washable Cover, Adjustable Straps - Image 5](https://m.media-amazon.com/images/I/81z3LO8vJRL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Questions & Answers **Q: Working from home and need some comfort on my dining room chair, would this work?** A: I use mine on a dining chair and I gotta say it makes a huge difference - its like a different seat, I'm not kidding. Old wooden kitchen chair now feels like a nice comfy office chair. No problems with the seat sliding off while i'm sitting on it. Backrest straps feel kind of flimsy but they do the job quite well too. All in all, good value for the price. **Q: Any good for driving car** A: I’ve found it invaluable. I have an autoimmune condition that attacks my joints, including my spine, and it makes driving a nightmare, limiting my range to about a twenty minute journey. Since buying the Fortem Chair Cushions, that range has really increased. I do feel a little bit like I’m pitched on something a little precarious at times, as it’s quite high (I had to lower my chair as well, as I’m already 6 ft 4), and I find that I take corners a little bit more carefully now, but treats not a bad thing. The two parts can be used separately, so you may just select the lumbar support for the car, if you do find the other makes you feel a little unstable, and keep that for a chair at home. The lumbar support attaches easily, with two elastic bands around the chair (I drive an Old Ford Galaxy and it easily fits that), and can be adjusted easily. The seat part is not attached, which means you can find the perfect placement, but does sometimes require a bit of faffing when you first get in the car. The two parts are very soft, but hold their shape well. They’re light, too, so if you’re transferring them between cars, or don’t always need it in the same seat, their weight isn’t a problem, although you would have to deal with the straps on the lumbar pillow (which shouldn’t be a problem). My wife doesn’t like it, but then again she isn’t gaining the benefits that I am, as she has no mobility issues. It’s also set up for me, of course, and she’s over a foot shorter than me. **Q: is this a back lumbar support AND a seat cushion ?** A: Yes, there are two separate parts. The lumbar support is attached to the chair back and there is a seat cushion to sit on. **Q: I have Exercise Bike with backrest the seat 38cm very large with a very large backrest will this help relief pressure** A: Yes absolutely if the seats are large and deep then it will definitely help relief pressure these items have definitely help me i hope this helps thank you ## Customer Reviews ### ⭐⭐⭐⭐⭐ Very comfortable *by S***A on 15 April 2026* Very comfortable.
