Abstract
Reinforced mattresses have a mattress core and one or more reinforcement pads located proximate to the mattress core, and corresponding higher density stitch patterns in a quilt package layer which are co-located with the reinforcement pads. The one or more reinforcement pads are located in higher load areas of the mattress such as the pelvic region or head and shoulders region to provide additional support and to resist or prevent permanent indentation of the mattress support surface and provide increased support. In one embodiment, the one or more reinforcement pads have a length that is less than the length of the mattress core and a width that is substantially the width of the mattress core, with corresponding areas in the quilt package layer of higher density stitching. The higher density stitching in those areas of the quilt package layer pattern provide a pre-compressed support structure in combination with the reinforcement pads which provides greater support and pressure distribution and resistance to permanent indentation of the support structure.
