Score: 85/100Rankings
The Serta CopperGel Cooling Pressure-Relieving Mattress Topper (Full) combines COOLcor gel foam and HeiQ Smart Temp technology for strong cooling and plush pressure relief, backed by a 10-year warranty. Its softer feel and potential off-gassing may not suit those preferring firmer support. Suited for hot sleepers with pressure-point issues.
Sealy's TrueForm 2-inch Memory Foam Topper adds gel-infused cooling foam and a removable cover, delivering strong pressure relief and CertiPUR-US certified safety. The soft feel may not suit those who prefer firmer support, and long-term durability data is limited. Best for side sleepers and hot sleepers looking to revive older mattresses.
