The Campus Deluxe mattress by Springwall is crafted exclusively for Costco using the highest quality components such as ViscoGel memory foam, and high density bio-foam.

All these enhancements are coupled with convenience and durability at a very affordable price. Proudly made in Canada with Canadian-made parts since 1949! All of the foams meet stringent CertiPUR-US standards for purity.
