The Ethical Mattress Co builds beds for people who want to know exactly what they’re sleeping on. This 10-Inch Hybrid in Full size contains only cotton, wool, natural latex, and pocketed springs. There are no petrochemical polyfoams, no fiberglass, and no toxic flame retardants. As of January 2025, the company also removed the rayon-poly blend from the design. It’s a short, honest ingredient list.

The top layer of organic latex relieves pressure points and keeps air moving through the mattress. That means you won’t sleep hot, even on warm nights. Below that, pocketed coils provide adaptive support and keep your spine aligned regardless of your sleeping position. At a medium firmness, the mattress hits a balanced feel—soft enough for side sleepers, firm enough for back and stomach sleepers. The full size works well for a single adult or a guest room where you want a clean, responsive surface.

One thing to note: this mattress is heavier than a standard polyfoam bed due to the natural latex and steel coils. Moving it upstairs or rotating it solo takes some effort. The tradeoff is a durable build that should hold its shape for years without sagging. If you’re avoiding synthetic materials entirely, this is one of the few options that actually delivers on that promise.
