Purple and Sealy Flexgrid are both made of Hyper Elasstic Polymer
HexGel is a unique gel material that provides pressure relief and cooling. It is made from a hyper-elastic polymer that can stretch when pressure is applied and rebound when it’s not. This technology results in a unique feel — whether you are a back, side, or stomach sleeper.
HexGel is also designed to provide airflow and temperature control. The honeycomb-shaped pockets in the gel allow for airflow throughout the mattress, helping to keep consumers cool while sleeping.
The Purple Grid is made up of a series of columns that are connected by a honeycomb-shaped mesh. The columns are made of GelFlex and the mesh is made of a breathable material. The combination of the columns and the mesh allows for airflow and cooling throughout the mattress.
