Slept on a 550lb mattress made of just cotton, wool and coils for a month. Here's the case for old-school beds

For nearly a month, the Naturepedic Serenade—marketed as an eco-friendly latex hybrid—was tested in queen-size with three firmness options: Plush, Cushion-Firm and Firm. The reviewer tried the Firm version, emphasizing support for back or side sleeping, and reports getting comfortable nights with “firm support” and some give. Testing included sleeping with a wife, dog, and two cats, tracking sleep patterns with an Apple Watch, and using weights to mimic different body types. The mattress type is a 11-inch latex hybrid with an organic cotton cover, a 100-night trial, and a 25-year warranty. It uses GOTS-certified organic materials and includes enclosed coil springs.
