Product Description

Meet the Diamond Brighton Copper Euro Top Mattress, a 12.5-inch mattress profile height crafted for soothing, all-night coolness.

A breathable euro top comfort layer finishes the feel with cloud-like plushness.

Because every layer uses CertiPUR-US certified non-toxic foam, you sleep free from harmful chemicals.
