Disclosed embodiments relate generally to the manufacture and assembly of mattresses, and comprise an interlocking system used to join foam support rails together to form a support frame about the perimeter of a mattress cover and/or a banding system for securing the support frame in place with respect to the mattress cover. The interlocking system generally comprises interlocking mechanical coupling portions at the ends of each support rail, allowing the ends of the support rails to be joined together to form a support frame without hard corner blocks that might reduce mattress comfort. The banding system comprises banding flaps that enwrap the support rails and attach them to the mattress cover. This allows for improved structural integrity during the assembly process, since the support frame is securely held in place.
