Jay J3 backrest. 41cm width and 46cm height, with light contour. In good condition, used since late 2023 on my quickie Nitrum and was a demo backrest before that, has plenty of life left in it. Reason for sale is my needs have changed and I have now got an alternative backrest. Only damage is the handle at the top is partially un stitched. Has been well cared for. Includes brackets on the backrest as shown, but not the ones that go onto the chair frame as I am still using them.
