Abstract
A mattress core unit, such as an innerspring, is placed inside a foam envelope, which in turn is covered with fabric. The side and end rails of the envelope overlap the bottom panel, to provide good support for all edges of the mattress. The top panel of the envelope overlaps the side and end rails. To make a reversible mattress, an overlapping bottom foam panel is used. The method simplifies matress construction, reduces the number of required stock keeping units, and provides a comfortable, yet firm, feel at the edges of the mattress.
