Stable, non-disruptive, and uniform independent support to each person laying on the mattress. Strong edge support for ease of entry and exit from the mattress without disturbing the other person. Excellent support for the back and all positions. Noticeable cooling feel to the body. Captures the contour of the body in whatever position you lay on the mattress. Although firm for support of the body, especially the back, the gel has a cushion feel and touch to the body. Even and smooth body conforming pressure. Great value too without being too expensive for a modern hybrid mattress.
