Serta Perfect Sleeper Hybrid Standard
Score: 77/100Rankings
The Casper Element Full Mattress delivers zoned support, solid edge stability, and a generous 10-year warranty with a 100-night trial. Its all-foam construction may trap heat and it isn't hypoallergenic, with some confusion over its exact weight. Ideal for back and stomach sleepers seeking supportive comfort and reliable warranty coverage.
The Serta Perfect Sleeper Hybrid Full offers a firm 12-inch hybrid design with 850-zone pocket coils and cooling gel foam, delivering strong support for back and stomach sleepers. Its drawbacks are the heavy weight and a firmness level that can be uncomfortable for side sleepers. Best suited for couples needing firm support and high weight capacity.
