Customer service excellent on organising return of faulty items- but unfortunately took over three months to actually follow through and get replacement.
Found out that the reason for return was in the end due to low quality product. Legs on chairs were always loose and after having for a couple of months now very uncomfortable. No padding at the front of the chair so wood cross member always sticking into underside of your legs. Thought I was picking a quality item but wished I'd paid a bit more and gone elsewhere. They do look good though.
