AB Lifestyles Visco Memory Foam Mattress Toppers for Campers & RV's are excellent quality and made specifically to fit the special size mattresses found in campers and RVs. We teamed up with an American mattress manufacturer to bring you a quality mattress topper at a reasonable price. Visco Memory foam was developed in 1972 by NASA. It is now routinely used in higher end mattresses. Visco memory foam is made of polyurethane and is hypoallergenic as well as dust resistant. It offers a more comfortable nights rest because it conforms to the shape and heat of the person lying on it. For this reason, there are no pressure points on the body. Campers and RVs often come with a mattress that leaves much to be desired! Because replacing the mattress is often cost-prohibitive, we are pleased to offer Mattress toppers to give you added comfort at a fraction of the price of replacing a mattress!
