I have a DezynaDog hydraulic grooming stool, bike seat style, not saddle.
It was bought last year at Crufts and has hardly been used. I just can't get used to grooming sitting down!
Its in perfect condition. Quite literally as new.
I would like £100 for it and, for convenience, I can take it down to Crufts with me to be picked up from there, to save on postage.
