Some office chair seat cushions I have tried have been too firm and uncomfortable. Is this sciatica seat cushion soft?** A: Yes. **Q: Can this tailbone pain relief cushion be used in a bathtub?** A: Hello! No, the chair cushion for back pain is made out of fabric and a firm foam material. It is not recommended to use in bathtub. Memory foam will absorb and hold water; it will be very hard to dry it out again. You should find one specifically for use in a tub. Overall this is not a memory foam seat cushion to use in bathroom. Best regards, Mike **Q: what are the dimensions of this item** A: This item measures 2ft wide by 14" Tall. The dimensions for all our items can be found in the Product Description section. **Q: Hello! Is this seat cushion for tailbone pain slip resistant?** A: No ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by L***M on January 8, 2020* ### ⭐⭐⭐⭐ Review *by M***R on January 30, 2012* ### ⭐⭐⭐⭐⭐ Review *by P***R on March 20, 2019* --- ## 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/139548000-seat-cushion-for-office-chair-seat-pad-memory-foam-orthopedic](https://www.desertcart.jp/products/139548000-seat-cushion-for-office-chair-seat-pad-memory-foam-orthopedic) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-04*
