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 ## Frequently Bought Together - FORTEM Office Chair Cushion and Back Support for Office Chair, Lumbar Support Pillow, Memory Foam, Non Slip Sitting and Back Rest for Gaming, Car Seat Cushion, Chair Pad - BlissTrends Foot Rest for Under Desk at Work-Versatile Foot Stool with Washable Cover-Comfortable Footrest with 2 Adjustable Heights for Car,Home and Office to Relieve Back,Lumbar,Knee Pain-Black --- ## 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.jp/products/470046106-fortem-seat-cushion-and-lumbar-support-for-office-chair-car](https://www.desertcart.jp/products/470046106-fortem-seat-cushion-and-lumbar-support-for-office-chair-car) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-15*
