Nothing like a half moon shaped cardboard... There's memory foam, but it's so firm, it might as well be a baseball bat.Btw, I'm pressing as hard as I can and that's how deep it gets???? Bffr!!! ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars I Sit On It *by P***L on Reviewed in the United States on August 24, 2023* I have sciatica pretty bad and can't sit for long periods on most chairs. This pillow is extremely firm, and when I put it on a chair and sit on it, there's sort of a bicycle seat effect and it takes much of my weight off of the pressure points in my butt. I can sit for long periods again. The manufacturer should advertise it for this use. Regular soft pillows are useless for me to sit on. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Amazing pillow *by N***D on Reviewed in the United States on January 9, 2024* Very good pillow quite hard and it’s for those who need a hard pillow and it’s memory foam comesback every time I have two of these one is old it just started becoming softer after 2 years so yeah it’s worth it ## Frequently Bought Together - URBAN SOMBRERO Trickonometry Lumbar Half Moon Pillows- Versatile D Shaped Roll Cushion Support and Bolster Pillow for Lower Back Pain, Under Knee, Neck Pillow, Leg Rest, Tension Relief (White) - Hydomi Orthopaedic Knee Pillow for Side Sleepers | Premium Memory Foam Leg Support Cushion with Cooling Cover for Sleeping | Adjustable Strap for Back, Hip & Sciatica Relief --- ## 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.ph/products/373885028-trickonometry-half-moon-extra-firm-pillows-versatile-d-shaped-half](https://www.desertcart.ph/products/373885028-trickonometry-half-moon-extra-firm-pillows-versatile-d-shaped-half) --- *Product available on Desertcart Philippines* *Store origin: PH* *Last updated: 2026-05-10*
