Help crawlers become bipeds! The varied terrain of our Woodscapes blocks provide challenging fun and encouragement to help first-movers build their mobility, coordination and confidence through exploration and play. The WB1475 Woodscapes Step features edges that are rounded over and sanded smooth for safety. The carpeting material is blue olefin (synthetic fiber, CPSIA compliant) that is renowned for its strength, colorfastness, comfort and resistance to stain, mildew, abrasion and fading from sunlight. Purchase the WB1475 separately [as shown] or as part of the WB1440 Woodscapes Hill and Dale Set that includes one of each of the following: WB1470 Large Platform, WB1471 Small Platform, WB1473 Hill Platform, WB1474 Valley Platform, WB1472 Ramp, WB1475 Steps.
