A foldable mattress and removable pillow top with a means for releasable attachment is not damaged during excessive folding such as when used in a sofa bed. Fastening pairs comprising zippers affixed to the mattress and pillow top in opposing complementary fashion with a wide fold space defined therebetween allow the mattress and attached pillow top to be repeatedly folded and unfolded and avoid crimping and damage to the zipper halves, mattress and attached pillow top.
