An exceptional tot seat. The dimensions of the seat are 12” diameter, 8.5” in depth and the back holes are 5 3/16” in length. It is made of 5/16” thick EPDM rubber with a one piece insert to resist vandalism and welded triangular hardware. Our seats are made of EPDM rubber that is made especially for our swing seats. The rubber does not rub off on children’s clothes and the seats last much longer than natural rubber swings. Unlike seats made of polymer, seats made of EPDM rubber hold up well in extreme temperatures, both very hot and very cold.
