If you need the cheapest mattress possible but require more than an air mattress or weak, uncomfortable spring that keeps you up at night - our All-Foam 6" Polypedic Mattress by Symbol Mattress is a supportive, comfortable answer that is made in the US! It's composed of CertiPUR-US foam (non-toxic) and offers a non-bouncy and medium-firm sleeping surface. A great short-term solution for dormitories, kids, guest rooms and even better when a topper is added! For a spring mattress that is nearly as affordable, have a look at our Andora Medium Plush Mattress. Optional solid wood foundation available for a small up-charge, when purchasing a mattress set. *Nearly always in stock and available to deliver to Ann Arbor and surrounding areas.
