On the building table, a coil spring is waiting. Flex, a plastic mesh, is laid across the coils. This prevents material from drooping into the springs. Larger mattresses will have foam cylinders placed in the spring coils along the perimeter and a hard foam slate across the middle for extra support. Here, a fibre pad is the primary layer. It's pulled tight across and around the springs.
Multiple hog rings are stapled through the pad, around the coils. The 3/4-inch foam is laid on the fibre pad. lt's laced through the corner coils and hog-ringed with a staple gun. The standard topper is added. The mattress is flipped; the same is done to the other side.
