Zippers have become an integral component of a mattress. Historically, spring mattresses have been most popular among consumers until a recent shift to foam mattresses due to their many advantages over spring mattresses. One highly desired advantage is the zippered mattress cover that encases the foam. During the manufacturing process, the utilization of a zipper to assemble the cover onto the mattress allows for a more simplified final assembly process. Advantages for the consumer using the zippered cover allows for the cover to be removed for washing while not affecting the aesthetics because the zipper is located in such a place where it is not noticeable. The zippered cover also allows the consumer to add or remove foam layers to adjust firmness or replace worn foam. Dunlap Industries is proud to offer exceptional products for the mattress industry.
