Alexander Signature Hybrid vs Zotto - 2024 Review

Our top layer, the ThermaPhase comfort layer, is the culmination of years of development. Our comfort layer combines two different phase-change materials that target temperatures on both ends of the optimal sleep zone. Upon reaching an ideal sleeping temperature, the phase change material undergoes a molecular transformation that works to maintain the temperature at the optimal level. This results in a mattress that will keep you cool when its warm, and will help keep you warm when its cold. There is not a more technologically advanced, or more comfortable mattress available, period. Our ThermaPhase™ comfort layer, is the culmination of years of development. We combined two different phase-change materials that react to temperature fluctuation. The result is a "Smart" mattress that will react to heat and actively cool the sleeping surface. OR if sleeping conditions become too cold, the Thermaphase molecules will redistribute absorbed heat to help keep you warm.

Each layer was engineered with varying levels of density and weight capacity to provide dynamic support. Our top 3 layers are a patent pending hybrid-foam package that we call Z3™. The Z3™ package utilizes various pressure ratings that only engage when necessary, providing the right amount of support and comfort for any size user, and optimal pressure point relief for back and joint pain.
