Our BEST mattress is a great value pillow-top/firm model. Designed around a 13 gauge 390 coil spring set with molded spring protection on both sides of the coils. The thicker coils create a firmer base on the pillow-top and the firm side. A cotton pad, and a layer of bonded cotton follow the molded spring protection. The needle-punched cotton pad lies under a 1 in. layer of comfort foam. Next the pillow-top is created from a layer of quilted cotton and a 1.75 in. layer of soft comfort foam topped with an antimicrobial fiber layer. Finally the fine damask cover is quilted to create a super value pillow-top/firm mattress.
