I now have three of Everlasting Comfort seat cushion - one in my car; one on my dining room chair and one in the TV chair. They fit well in every chair / seat. I have sciatica and took this with me on a trip, with little pain on a long airplane ride. The quality seems good for the six weeks I've had the first one, with the foam still firm. I enthusiastically recommend this pillow - especially good value! ### ⭐⭐⭐⭐⭐ Seat cushion for support *by on Reviewed in the United States 16 July 2025* Very comfortable can use any place. I use it in my car to help support my restless legs while driving. I love it..it helps my pain. I highly recommend this for anyone that needs a little comfort. Great price it's thick in all the right places. And it's functional and stays in place in the seat. ## Frequently Bought Together - Everlasting Comfort Doctor Recommended Memory Foam Seat Cushion for Office Chairs & Car Seat - Ergonomic Office Desk Accessories for Tailbone Pain Relief, Sciatica & Back Support - Everlasting Comfort Doctor Recommended Memory Foam Seat Cushion for Office Chairs & Car Seat - Ergonomic Office Desk Accessories for Tailbone Pain Relief, Sciatica & Back Support - Everlasting Comfort Doctor Recommended Memory Foam Seat Cushion for Office Chairs & Car Seat - Ergonomic Office Desk Accessories for Tailbone Pain Relief, Sciatica & Lumbar Support --- ## 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/726646622-everlasting-comfort-doctor-recommended-memory-foam-wedge-seat-cushion-office](https://www.desertcart.jp/products/726646622-everlasting-comfort-doctor-recommended-memory-foam-wedge-seat-cushion-office) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-28*
