Barstool needs tightening, the gaffer tape taking off the bottom, and a screw has been tightened too far and caused a little but of bulging on the seat, plus some brasso on the metal so wouldn't go amiss.
The four chairs are two sets of two, the only real difference is in the stitching on the back rest. They are all rough (cat scratches, split vinyl etc), and really need recovering. They also need something doing to the seat as they are all cracked underneath. It would still be cheaper than new chairs (phew, do new chairs cost a lot). I will split. Pick up in Wigmore any afternoon or evening.
