Abstract
A mattress (22) having a foam core (8) completely extends to the perimeter edges of the mattress wherein side walls (15) of the foam core are compressed inward and held in place using a preferably non-woven strip of fabric (21) or similar non-elastic or non-stretchable material that is wrapped around the side walls of the foam core. A method of wrapping the foam core allows corners (5) of the foam core to be formed under the inward pressure of the non-woven fabric, thereby creating a strong perimeter for the mattress that prevents outward pressure against the sidewalls created by the downward pressure of an individual lying on the mattress from flattening of the mattress by providing more upward pushback against the individual. An optional layer of micro-coil springs (2a) may be located within the foam core to provide more buoyancy and springiness in the mattress.
