Maidenhead GB
Comfortable seat, sturdy and solid.
The flexible back is quite stiff and doesn't move as easily as on other, more expensive, chairs. Also it is squeaking when I lean back, after only a couple of weeks' use.

Very comfortable. Have back problems from old chair. Surprising how you take it for granted that the chair you have is not what's making your back ache - but believe me it was!!

Easy to put together ..klunk klick - no tools needed. if only life was like that! Good quality material.
