Our high-backed special needs swing seat has been providing a supported ride to generations. It has been much copied, but never bettered. The soft and breathable harness combines with a pommel to ensure safety. Snap buckles make for quick transitions. Quick links make them easy to hang from most frames. Soft ropes are pleasant to touch and full adjustment both in terms of height and rake on frames up to 10' high They can be left outside all year round (UV resistant.) Moulded from high-density polyethylene, a strong but soft plastic. Choose either Child, Teenage or Adult size. Child 56 x 33 x 30cm (H x W x D) Teenage 69 x 43 x 34cm Adult 81 x 51 x 36cm Its a good idea to measure the hips of the user and compare with the width of the seats: 33, 43 & 51cm as this is usually the critical dimension.
