Mattress assemblies including a hybrid posture support system
Mattress assemblies include a hybrid posture support system that provide an end user with improved posture support during use, among other advantages. The hybrid posture support system includes a top foam layer including first and second foam portions that are spaced apart and generally correspond to a head/shoulder region and a foot region, respectively, a pocketed microcoil array underlying the top foam layer that is intermediate the first and second foam portions; and an underlying foam layer. The hybrid posture support system can be used in any mattress assembly including mattresses having a coil spring innercore or a foam innercore.
