The 8TRL/9TRL/Webster Lite 2 AP/SP Cushion is a great addition to the 8TRL/9TRL/Webster Lite 2 AP/SP range. This cushion provides you with more comfort, keeping you comfortable all day long. We know spending hours in a wheelchair can become uncomfortable so we had to bring this product into the market and it fits our 8TRL/9TRL and the Webster Lite 2 ranges.
