Overview
Sweetnight layers a cool touch cover and phase change foam over gel memory foam and individually wrapped coils in this king hybrid. A high density foam border firms up the edges for sitting and sleeping near the side.
Hot sleepers get three cooling stages, and couples benefit from coils that isolate motion. The pillow top relieves pressure at shoulders and hips. Thickness and warranty terms are not given in the bullets.
Who it's for
Couples who disturb each other, side sleepers needing pressure relief and people who wake up warm get a cooling, supportive hybrid. Those who want a plush sink-in feel or a hard surface should look at other firmness levels.
Pros and cons

Performance notes
Individually wrapped coils compress independently, so movement on one side barely reaches the other. Phase change foam absorbs body heat, and the gel foam layer spreads pressure across the shoulders and hips.
