Contoured to accommodate your posterior at all points, except coxccys to provide relief from pain. It's comfortable to sit on, having that right blend of softness, yet firm. I bought it for my upcoming hemorrhoid operation, which I haven't received my appointment yet. ### ⭐⭐⭐⭐⭐ CComfortable cushion *by S***K on 21 February 2026* Pretty comfortable and has stopped the pain I was getting sat at my computer. Others have said the cushion doesn't slip but I can't agree. This may be down to the chair I am using but it's easy enough to push back into place. I would ta== rather have to occasionally move the cushion than suffer the pain in my tailbone. ### ⭐⭐⭐⭐ Takes a week to adjust, but helped with tailbone discomfort *by D***N on 6 November 2025* Takes some getting used to, but it does help over time I bought this because I was getting pain in my tailbone area from sitting for long periods at my desk (work and gaming). At first it felt a bit strange to sit on. For me, it took about a week of daily use to get used to it, and that’s around the point where I started noticing the pressure easing and the discomfort improving. Once I settled into it, it did help make longer sitting sessions more comfortable. The design spreads your weight more evenly and takes the pressure off the tailbone. So if it feels odd at first, I’d say stick with it and give it time rather than judging it straight away. The cover has a zip so you can take it off to wash, which is a nice practical touch. Mine has held its shape well so far and still looks the same after regular use. The only thing to mention is the price. It works, but it does feel a little on the higher side compared to some similar options. I’d say it’s good value if you can grab it when it’s discounted. I got mine at full price. Overall, not an instant fix, but it genuinely helped after a bit of adjustment time. Worth considering if you spend a lot of hours sitting. I have mine on a secret lab titan chair for size comparison in my pictures. ## Frequently Bought Together - ProtoArc Seat Cushion for Tailbone Pain Relief, Office Chair Cushion, Coccyx Cushion, Ergonomic Memory Foam Seat Cushion for Home, Car, Pressure Relief Pad for Hip, Coccyx, All Day Comfort - Black - Everlasting Comfort Doctor Recommended Memory Foam Seat Cushion for Office Chairs & Car Seat - Ergonomic Office Desk Accessories for Tailbone Pain Relief, Sciatica & Back Support - QUTOOL Lumbar Support Pillow for Office Chair,Office Home Essentials,Back Support Pillow for Car, Chair Cushions,Back Pain Relief Improve Posture,Mesh Cover Double Adjustable Straps --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/663485051-protoarc-office-desk-chair-cushion-ergonomic-coccyx-cushions-memory-foam](https://www.desertcart.vu/products/663485051-protoarc-office-desk-chair-cushion-ergonomic-coccyx-cushions-memory-foam) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-06-07*
