We think you'll find that the unique design of our Butterfly wagon is perfect for small children. The double seats of hand-carved willow have comfortable, tilted back rests, and the side rails make it easy to hold on. The deck is made of 5/8" thick birch planks, joined together in a durable tongue-and-groove joint. A marine-grade finish (lead-free of course) protects the wood of the wagon, and all screws and bolts are of stainless steel for durability. The rugged steel undercarriage is powder-coated, and the inflatable tires provide excellent shock absorption. Adult assembly required; assembly is easy -- all you have to do is tighten the 7 bolts that connect the undercarriage to the wooden top, plus the bolt that attaches the extra-long handle. The Butterfly wagon meets all USC and ASTM child safety standards. The finish is lead-free. Assembled size: 38"L x 15"W x 19"H, 32 lbs.
