The S135 is very similar to our S130.
It has galvanized welded hardware that connects to a stainless steel insert. It is made from a mixture of EDPM (rubber) and a rubber-like polymer EVA, making it extremely lasting, as well as doing well in extreme changes in weather. We believe our seats are made to the highest standards available. Customers cannot see many of the extra hidden safety features. Uninformed users may think our seats and another suppliers are the same. However, they may not have added the hidden safety features that we have because of the added costs. We feel these safety features benefit the strength of our swings and the well-being of the children that use our equipment. The seat’s insert rounded edges to help prevent injuries from sharp edges and then encased in EPDM rubber. The seat should last 2 years in harsh conditions and up to 5 years in optimal conditions. Some conditions may require replacement sooner.
