Our luxury latex mattress features a latex foam core, latex padding and a layer of wool. This set is just as supportive but contains no innerspring. The Nature’s Impressions reduces pressure on pressure points and minimizes motion transfer. This mattress is available as a Soft Top or Ultra Soft Top. Both offer the same benefits. The Soft Top is firmer, featuring denser latex foam in the core and padding layers. The Ultra Soft is much more contouring to the body for a softer, pillow-like feel due to lower density latex foam.
