I’m very happy with this purchase! It’s incredibly soft and comfortable while still providing a nice level of firmness and support. I’ve been sleeping really well on it.

I initially thought they would fully expand and return to their normal shape over time, but they still seem to be that way. Aside from the corners, I’m very satisfied with everything else. It’s comfortable, supportive, and I’ve been enjoying it so far. I would definitely recommend it!. Anonymous. Fri Oct 16 2026

OUR FIRMEST MATTRESS FOR MAXIMUM SUPPORT: This is the firmest mattress we’ve ever made. Two layers of 14-gauge coils—far stronger and more durable than those of other brands—combined with high-density natural materials, provide a solid, stable sleep surface that resists sagging and delivers ergonomic alignment, even under heavier weights. Because more coils mean more support, it proudly features up to 2,112 individually wrapped coils, which also improves responsiveness and pressure distribution. While the feel softens slightly for the heaviest sleepers, it remains definitively firm (10 out of 10) for lasting support for back and stomach sleepers. Side sleepers can add an Organic Mattress Topper for added contouring and cushioning.
