Mattress Hero® recommends the you have a solid base with our products. We do recommend a New Wood foundation with your purchase to avoid any warranty issues. If your current Foundation or Box Springs are in good shape, no sags, squeaks or cracks, you can use it with your new mattress. To keep your investment in tip top shape it is wise to have a sturdy, supportive foundation to put your mattress on and could void your warranty if you mattress is placed on a defective foundation or box-spring.
