We designed our mattress to be strong, reliable, and durable. Our mattress is able to work on a variety of foundations as long as their is plenty of support. Traditional box springs do not meet our requirements for support, and we do recommend that you purchase a full set of both mattress and box spring to accompany our mattress. Our mattress was designed together with our box spring and purchasing both the mattress and box spring together ensures the highest level of comfort. Many customers do choose to use their existing box spring and purchase the mattress only.
