Whether they're a teething toddler or a growing teen, help your child wake refreshed with the Tuft & Needle Glee mattress. Featuring a foam construction for cradling comfort, this mattress offers innovative cooling, responsive pressure relief, and the bounce-back support of T&N Adaptive foam, so they can sink deeply into sleep-but never into the mattress. Unlike memory foam, Tuft & Needle's T&N Adaptive foam doesn't sink under weight. Instead, it keeps each sleeper lifted while contouring to relieve pressure where they need it most. With the addition of a breathable cover and reinforced edge support for corner-to-corner comfort, the Tuft & Needle Glee 9" Medium-Firm mattress ensures your child can sleep well, and wake refreshed, for years to come.
