About This Product

Get the cool, undisturbed sleep you’ve been craving with this Full Size 11” medium feel hybrid mattress. The performance fabric wicks away heat and moisture—no more waking up sticky or overheated! Copper-infused memory foam pulls excess warmth from your body and cushions pressure points, so you toss less and sleep deeper. A hi-def transition layer adds a buoyant, weightless feel (like sleeping on a cloud!), while 740 individually wrapped coils stop motion transfer—perfect for couples (your partner’s moves won’t jostle you!). Greenguard Gold certified (safe for your home!) and made in the USA, it’s built to last. The sleek black polyurethane cover is easy to spot-clean, so it stays fresh. Ideal for side, back, or combo sleepers—this mattress checks all the boxes for comfort, quality, and value.
