Our PREMIUM mattress is a luxury 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 heavy density foam follow. The needle-punched cotton pad lies under a .375-inch layer of heavy density foam, which is topped with an inch layer of 2.6 lb density high resilient foam. Next the pillow-top is created from a 1 inch layer of visco elastic memory foam followed by quilted cotton and a 1.5-inch layer of super soft plus comfort foam topped with a 2-inch layer of antimicrobial fiber. Finally the fine damask cover is quilted to create a premium pillow-top/firm mattress.
