Extra-Firm Comfort, High Value

If you’re looking for an extra-firm starter bed, this is the mattress for you. Pocketed coils adjust to your body throughout the night, while firm upholstery foam and the unquilted top panel allow you to lie flat. The cover uses a breathable, stretch fabric cover with cooling elements that deliver a high-quality bed at an affordable price.
