Hybrid mattresses combine the structural component of an innerspring mattress with the pressure relief and comfort of a foam mattress. They typically contain springs on the bottom, supportive layers, and foam on top. How much foam a hybrid mattress has, or what type of comfort material it includes, varies. Many people sleep well on a hybrid mattress.
They’re also known as CvRDTs (“Cv” standing for “convergent”) and CmRDTs (“Cm” standing for “commutative”), respectively, although I think “state-based” and “operation-based” are the preferred terms. ↩
