This mounting hardware for the seat contains a pair of steel springs to absorb significant shock and force created by the client. The energy absorption acts to protect the integrity of the wheelchair frame by reducing stress that would be applied to it as well as increase the possibility of reducing the extensor patterns exhibited by the client.

All hardware used to mount the solid seats and solid backs are steel: most components being stainless steel. The metal is first treated to retard rusting and then oxy coated with a black finish to provide a more appealing appearance.
The choice of metal used was based on tensile strength and the overall durability/longevity it would provide. The decision to oxy coat in black was so the brackets matched our attaching fasteners (nuts, bolts and washers) which are also black oxy coated stainless steel. This is done to improve the appearance of our finished product by having all brackets and fasteners blend in with the seating system.
