Mattress Safe protective encasements for Sleep Number beds are now available for common bed sizes. Mattress Safe has designed its Sofcover Superior encasements with special sleeves for the air hoses that provide protection against bed bugs entering or leaving the encasement. The Sleep Number mattress can now be used and protected at the same time. The Superior Mattress Encasement continues to stretch to fit 9- to 15-inch depths and is also available in Plus+ Advantage sizes. It remains bite-proof as well as penetration and escape-proof, with the same waterproof, hypoallergenic and fire-retardant benefits. Ask about Mattress Safe’s 10 SKUs Program.
