The containment system which keeps side-by-side mattress (14, 15) together consists of a head (16) and foot (17) containment block extending across the top and bottom respectively of a pair of adjacent mattresses. The head (16) and foot (17) containment blocks make up a portion of the sleeping surface and are of a sufficient size and strength to prevent lateral outward movement of the pair of adjacent foam mattresses (14, 15). The mattress assembly has a stack of foam mattress elements with one of their peripheral edges joined together such that the stack of foam mattress elements remains in a vertical stack. Bedding for the mattress assembly is secured around the outer edge of the mattress or around the outer edge of the containment system by using a retainer rope tensioned around the mattress to hold the bedding into a groove extending at least partially around the mattress.
