The ultimate in luxury, the TopAire Topper gives new life to any mattress that needs the feel and adjustability traditionally only offered in an expensive air number bed. Personalize each side of the bed from firm to plush to everywhere in between for comfort that fits your body. Unlike traditional memory foam, gel, or latex mattress toppers that sink and break down over time, TopAire uses an innovative dual-chamber design to provide you with an adjustable, custom sleep surface that offers 4 full inches of support. Ranging from ultra-luxury firm to a delicate, body-cradling plushness, sleeping on Top Aire gives you the personalized support, cooling comfort, and overall sleep experience you both demand.
