The EVA Foam Tables are expertly cut from soft, sturdy EVA foam - the same material that you'll find inside your athletic shoes. The foam makes them comfortable, safe, lightweight, durable, strong and washable. You'll find that their child-size proportions belie their strength - each piece can support a weight up to 300 pounds! Eva Foam Tables, Chairs and Stools are equally happy indoors and outside. Modularity allows all three pieces to stack together. So go ahead and take a seat, rest your feet, stack them like blocks, make a sculpture, create a room divider...
