Hybrid mattresses come with impressive warranties as well as sleep trials. However, the question that comes to mind is that hybrids haven’t been on the market for a long time and facts do not back their extended warranties. So how are they so confident about their mattresses?
There is one specification that you can closely monitor when buying your favorite hybrid: density. The foam layers and their densities that you will come across during your search include:
- High-density polyurethane foam (1.5 to 2.5 lb/cu. ft.)
- Memory foam (3.5 to 4.0 lb/cu. ft.)
- Latex (3.75 to 5.9 lb/cu. ft.)
