ABSTRACT:
A modular mattress having a plurality of innerspring modules with a peripheral border strip extending around the periphery between the top mattress cover and the bottom mattress over. The border strip is connected to one or the other of the top or bottom mattress covers by sewing, and to the other by releasable connecting means such as a zipper. A fabric flange extends from the peripheral edge of both the top and bottom mattress covers, with a Velcro strip or the like along the free edge of each fabric flange. Each innerspring module has a side wall strip of material along its outwardly facing side wall with an upwardly extending flap having a cooperative Velcro strip along its free edge to releasably connect to the Velcro strip on the fabric flange of the top mattress cover, and a downwardly extending flap having a cooperative Velcro strip along its free edge to releasably connect to the Velcro strip on the fabric flange of the bottom mattress cover. The zippered edge of the peripheral border strip is zipped up to releasably connect it to the mattress cover having the corresponding zippered edge.
