“It's great that these spares are available, because the castors break quite easily. The shaft of the replacement is a bit slimmer than that of the castors that came with the chair, but you can wrap them in tape or cardboard and they stay put reasonably well.”
“Sadly, the model supplied (the only one available) differs slightly from that used in my kneeling chair (shaft is smaller and so is too loose in the fitting), but with a bit of cardboard and some improvision I can at least use the chair again.”
