The Saatva Classic mattress is an innerspring model designed with an organic cotton cover, a plush Euro pillow top for comfort, a thin layer of memory foam for pressure relief, individually pocketed comfort coils, and a durable steel coil base.
Nolah Evolution 15”, on the other hand, is a hybrid mattress that incorporates a cooling ArcticTex™ cover, a layer of graphite-infused AirFoamICE™ for pressure relief and cooling, a high-resilience foam transition layer, and a robust base of tri-zoned support coils.
