Review: Comfortable and Gives My Office Chair a Second Life - **Comfortable and Gives My Office Chair a Second Life** I’ve been using this cushion on my office chair and like it so far. It adds enough support and comfort that I can keep using my current chair instead of replacing it right now. It feels comfortable for longer periods of sitting, and so far it has been a worthwhile upgrade. The real test will be how well the foam and shape hold up over time, so I’ll see how it does with continued use. I may also try it in my vehicle on longer trips since it seems like it could make extended driving more comfortable. ## Features - [Thick Cushion] The seat cushion measures 18.11" x 16.14" x 5.2" and includes about 3.9" center thickness medium firm memory foam gently conforms to your body, giving you a comfortable experience.

I would definitely recommend it. It is very thick but NOT soft. I’d say it’s a medium density. I need a soft cushion. This will not ease my post surgery hip pain at all. I will use it for a long time, but still searching for absolutely soft cushiony for right now. ## Frequently Bought Together - BlissTrends Seat Cushion,5.2in Thick Memory Foam Cushions for Office Chair, Car Seat, Airplane, Relieving Pressure Tailbone Sciatica Back Pain for Long Sitting Office Workers, Car Drivers Black - QUTOOL Lumbar Support Pillow for Office Chair Back Support Pillow for Car, Computer, Gaming Chair Memory Foam Back Cushion for Back Pain Relief Improve Posture, Mesh Cover Double Adjustable Straps - 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.tn/products/604613423-blisstrends-thick-seat-cushion-for-office-chair-and-car-seat](https://www.desertcart.tn/products/604613423-blisstrends-thick-seat-cushion-for-office-chair-and-car-seat) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-14*
