Hybrid Mattress

Hybrid Mattresses combine the best of both worlds coils and foams. The coils are typically a wrapped coil that works independently from the rest of the coil system. The hybrid coil is generally shorter in size to adapt to the foam material that lays on top of the coil system. The foam material can be latex for a springy up-lifting feel, gel memory foam for a cooling sinking feel, open-cell adaptive foam that conforms to the body with body temp, or memory foam.
A Hybrid mattress is great for all types of sleep styles. The perfect hybrid mattress sleeper is one who likes the conformability of Memory-foam but does not like the "sinking in" feeling that memory foam offers. For those who enjoy sleeping on latex a latex hybrid mattress offers an affordable option to a 100% Latex mattress since coils are less expensive to manufacture than all natural latex from the rubber tree.
