The Hybrid mattress is ideal for side sleepers. It sleeps cool, has bounce to it without the motion transfer, and has strong edge support. The top layer of foam circulates air, so you don't sleep hot while also having a fast recovery time. The memory foam in the middle provides pressure relief. The individually wrapped pocket springs provide bounce, targeted pressure relief, and even more air flow. Being individually wrapped allows the springs to work independently of each other, so they can support the different weights and pressure points of your body. With the Hybrid you get the best of both worlds: the contouring effect of the foam and the extra support from the springs.
