This a fully enclosed infant one piece seat with a high back to offer extra support for smaller children. This swing has a smaller leg opening, ASTM F2373, for children 6 to 23 months. The dimensions of the seat are 39" circumference, 11" deep, the front leg opening is 3.5" leg with the back opening 3.75".
Made of 70 duro EPDM rubber with an insert and heavy duty rust resistant welded triangular hardware. EPDM: Ethylene-propylene-diene-monomer is a synthetic rubber material which helps prevent crazing, cracking and oxidizing.
Natural rubber is often made from recycled tires etc., and you are never sure what the actual rubber mixture is. It often wears off on children's clothes. It cracks and crazes, making the seat unsightly and allowing moisture to get into the seat.
This makes the seat deteriorate at a much quicker rate. 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.
