Our SUPREME mattress set is a super pillow-top/firm model. Designed around a 14.5-gauge coil lura-flex spring set that offers over twice as many individually wrapped coils compared to our GOOD, BETTER, and BEST models. Beginning with molded spring protection on both sides of the coils, a cotton pad, and a layer of bonded cotton follow. The needle-punched cotton pad lies under a .5-inch layer of comfort foam, which is topped with a .75-inch layer of heavy density foam. Next the pillow-top is created from a layer of quilted cotton and a 1.5-inch layer of super soft comfort foam topped with a 2-inch layer of antimicrobial fiber. Finally the fine damask cover is quilted to create a supreme pillow-top/firm mattress. This mattress is paired with a matching box foundation to complete the set.
