Manufacturer warranties cover any mattress defects such as a damaged edge, sagging of more than an inch, separating of any stitching or embroidery, broken spring/coil, and/or any other manufacturer defects. There are three scenarios that would void most mattress warranties; the first being cutting off the law tags located at the head of the mattress. Secondly, any stains or non-defect related tears on the mattress. Thirdly, if your mattress lacks proper support from its foundation, your warranty will be void. According to warranty policy, any warranty claims should be processed through the manufacturer directly. Here at Mattress Central Stores, we encourage our customers to immediately bring any warranty concerns to our attention for a hassle free, effortless, and expedited experience. We won’t keep you on hold, we promise!
