A thick 4-inch copper-infused foam topper that pulls heat away as you sleep. The washable cover has anti-slip backing and straps so it stays put on the bed.

Quick verdict

A thick, plush 4-inch copper-infused topper that adds real cushioning while copper carries heat away from the surface. The included washable cover has anti-slip backing and straps so it stays put.

What earns it the pick

  • Copper helps transfer heat away from the body
  • Drift-Cool washable cover
  • Anti-slip backing with adjustable straps
  • Queen size

The honest catch

What we’d want you to know before you buy.

  • 4 inches raises mattress height and may need deep-pocket sheets
  • Memory foam still retains some heat even with copper
  • Thick foam is heavy to move and slow to expand at first
  • New foam can have a mild odor that fades
