Sweetnight Coolnest 16 Inch Queen Size Hybrid Mattress vs Novilla AiryFlow Graphene Hybrid Mattress

Both are medium-feel hybrids in a box with cooling covers and CertiPUR-US foam. The Sweetnight Coolnest is the taller, plusher build at 16 inches with a pillow top, so it suits side sleepers and heavier bodies who want deep pressure relief. The Novilla AiryFlow is a 12-inch Euro-top with graphene and perforated gel foam, and it adds a 100-night trial and 10-year warranty, which Sweetnight does not spell out here. Owner ratings are close, 4.5 versus 4.6, so pick on height, feel and warranty rather than score.

• Choose the Sweetnight Coolnest if you want a thick pillow-top hybrid with deep contouring for side sleeping or a heavier frame.
• Choose the Novilla AiryFlow if you want a lower-profile medium mattress with a documented sleep trial and 10-year warranty.
