Serta iSeries NXG Mattresses Overview
GoodBed Editorial
Summary: Serta iSeries NXG Overview The new Serta iSeries NXG Collection replaces the outgoing iSeries models and upgrades these with new memory foams, multi-level cooling features, and all-foam and hybrid designs. All of these are built with a smooth, very high stretch cover that maximizes the feel of the underlying high-performance foams. They also add some very high density foams. We’d even call some of these Ultra High Density - our highest density category in memory foam.
