Diamond Lagoon Review

Rating: 8.3
Verified
Buy Diamond
The Diamond Lagoon mattress is a hybrid model that combines sustainable materials with a balanced feel, offering medium firmness. It excels in cooling, response time, edge support, and sex performance, but has higher motion transfer and significant sinkage. It features a 4-inch comfort layer and an 8-inch pocketed coil system for support. The mattress is competitively priced at $999 for a Queen size and comes with a 120-night trial period and a 20-year warranty. Overall, it is a strong contender for those seeking a sustainable and supportive sleep surface.
