Six soft play blocks create an indoor course that lets babies and toddlers crawl, climb, slide and sit while building gross motor skills. The set includes a small 8 x 8 x 4 in rectangle and a larger 16 x 16 x 8 in rectangle for stacking or stepping. A 16 x 20 x 8 in half cylinder, a 16 x 8 x 8 in gray ramp, a cylinder and a 24 x 16 in trapezoid let adults vary the layout. Lightweight pieces are easy to move between rooms. EPE foam cores under PU covers provide cushioning, and the waterproof surface wipes clean for quick maintenance.
