I bought a PRO XL Series - Leather / Black in February 2022. Was very pleased with it until the tilting mechanism jammed in July24. They sent a replacement mechanism and all was fine until a week ago. Not only did the mechanism break, but the steel wire holding the bottom of the chair together snapped and I ended up on the floor. I rang customer service, they were happy to sell me another tilt mechanism but not interested at all in the structural failure of the chair. 3 years use for a £200 chair is not acceptable.
