Every mattress should be covered by a mattress protector. Not only does the protector keep the mattress sanitary and free of stains, it also helps keep out allergens such as dust mites. Protectors also insure that the manufacturer’s warranty is valid since stains void mattress warranties. At Mattress Lot we have a wide variety of protectors, including our Premium Bed Tech Queen Size Protector for $39, a five-sided Tencel Luxury protector, our Coyuchi organic cotton flannel protector and a variety of fully encased (dust and bed-bug protection) mattress protectors. All of our protectors are breathable and come with a 10 year warranty. When you use a mattress protector from Mattress Lot, you can take advantage of our sleep guarantee (excludes value line and clearance mattresses).
