Rating: 8.0

Buy Diamond
The Diamond Sage mattress is a latex hybrid mattress that emphasizes natural and organic materials. It has an overall score of 8.47, excelling in cooling, response time, edge support, and pressure relief. However, it has drawbacks in motion transfer and deep sinkage. The mattress features a medium firmness, a 12-inch thickness, and is priced at $1,699 for a Queen size. It has a breathable latex and pocketed coil design, providing excellent cooling and high bounce, which is beneficial for sex but may contribute to motion transfer issues. The mattress offers good edge support and minimal noise, making it suitable for various sleeping positions. It has a moderate off-gassing smell lasting about 8 days. The company offers a 120-night trial and a 20-year warranty.
