Advanced Technology

The Restore Plus Copper 12" Foam Mattress by Diamond delivers healing copper-infused recovery sleep for every position.

At a true 12-inch profile thickness, plush copper-infused memory foam layers cradle pressure points while naturally creating an anti-microbial sleep surface.

Next, a Cool Touch temperature-regulating fabric cover partners with advanced temperature-regulating foam technology to keep hot sleepers comfortably cool all night long.

Moreover, a high-density support foam base (a CertiPUR-US certified foam core) stabilises the body, easing hips, shoulders, and lower back.

Because of this balanced design, couples enjoy calm motion isolation and pressure-relieving memory foam comfort, whether they choose Firm or Medium feel.

For long-term peace of mind: a 120-night sleep trial, Diamond Mattress's 20-year warranty, and free shipping across the USA let you experience dream-worthy rest risk-free.
