CopperFlex® 201 Mattress Topper

The CopperFlex 201 is a 2-inch copper-infused memory foam mattress topper — the least expensive way to change how your current mattress feels without replacing it.

Two inches is the right depth for adjusting surface feel rather than overhauling firmness: it softens a bed that sleeps slightly too firm and adds a layer of pressure relief. Copper infusion conducts heat away from the body and brings antimicrobial properties. Six sizes, twin through CA King.

A common pick for dorm rooms, where it makes an institutional twin XL mattress genuinely comfortable.
