What child doesnt love sleeping in a tent? Easier than camping out (and more comfortable!) these bed tents fit right over a twin bed with outer skirts that hold the tents securely to the mattress. Each tent is 77Lx38Wx35H. Mesh panels offer ventilation and viewing ease. Three sides are closed while one long side features two flaps that can be left down or held open with Velcro straps at the sides. Tents can also be used off the mattress as a regular play tent. These might be especially helpful for kids who are just starting to sleep in a big-kid bed instead of a crib. Made from 190T Polyester Taffeta fabric.
