The Room to Grow 4-in-1 Inflatable Play Yard is not only a safe place to develop motor skills but can be used for a sleep space, changer or splash pool. Play Yard has two handles so you can move it indoors or out without taking it down. There are mesh window ports for cross ventilation and viewing for baby and caregiver. As a sleep space, the 4" removal able cushion has internal structure for added support. The air channeling across the surface of the cushion and the fitted soft cotton sheet provide added comfort to baby and cleaning convenience for caregivers. Extra single sheets can be ordered separately. As a changer, simply turn play yard upside down. The natural hammock formed by baby will help to center him/her for changing. As a splash pool, simply remove cushion and add water for a fun place to splash or bathe.
