First of all, it looks really nice. Second, it’s very very comfortable. It’s labeled as medium firm but honestly I’d say it’s more on the firm side. We have a king size and it’s a great 2 person sleeper, no disturbances or movement when the other person is moving around. It’s also been really good for my back and hip pain. If you’re looking for a good quality, comfortable mattress, at a really affordable price, you won’t be disappointed with this one. ### ⭐⭐⭐⭐⭐ An excellent mattress *by R***A on July 17, 2025* This is totally worth it, totally.I was nervous about buying a mattress online because my idea of firmness or softness is more than likely different from someone else's. But, I got lucky, it's perfect.I don't really want to use the terms soft or firm. It's supportive without being firm. It's plushy without being too soft and unsupportive.I'm comparison to a memory foam mattress, it's nicely supportive. I don't feel like I'm sinking, but have all the comfort of memory foam. Compared to a traditional inner spring, soooo much more comfortable. I don't feel like I need a topper.My husband demanded a 14", and yeah, it's definitely 14 inches. I don't know if it's worth it to get that much mattress over a 12", but that's a personal choice.I do find it a bit too squishy on the sides, but I am getting used to that (it's been 3 weeks). ### ⭐⭐⭐⭐⭐ Pleasantly Surprised. *by C***7 on July 17, 2025* I just needed a cost effective king size mattress as I was not planning on keeping it very long. At this price point, I was not expecting much, but this mattress pleasantly surprised me. It is the perfect firmness (I would say a tad firmer than medium-firm) and very comfortable to sleep on. I love the fact that it is a hybrid mattress with coil springs and memory foam. It sleeps pretty cool, but as with any mattress that has foam, cotton sheets and blankets help a lot with heat regulation.The setup process was quick and easy -- with the mattress expanding to full height well before the specified time on the directions. Definitely a solid choice for comfort, price, and convenience. --- ## 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/746490214-full-mattress-12-inch-hybrid-mattresses-black-with-gel-memory](https://www.desertcart.jp/products/746490214-full-mattress-12-inch-hybrid-mattresses-black-with-gel-memory) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-19*
