Excellent for developing physical agility and balance, this set includes eight pieces in two different styles: one with stripes and one with dots. The stripes and dots are anti-slip rubber for sure-footed fun, and the same rubber also runs along the bottom edge of each piece to ensure that they will stay in place on hard surfaces such as wood or tile floors, and on soft surfaces such as carpet or rugs. The pieces connect together with a simple but secure lap joint that is easy to snap in place. The wavy path can also be used outdoors, and comes with a handy carry bag for storage and transport, as well as a booklet of suggested activities. Each piece measures about 61 cm (2 feet) long and 12 cm (about 4.5") high at its peak. Maximum load: 80 kg (175 lbs).
