Now have a replacement for my old chair - There is nothing wrong with it -it's comfortable -stable -solid -tilts -tilt lock -seat and armrests adjustable -back goes up and down but it was made in Feb 1996 so looking used now and tilt lock jumps out. Been looking for a replacement and this is it -Shop Demmo chair- few stains and fading but it is just as comfortable - Has all of the above except total tilt lock - this justs restricts movement. -There was a stain on front edge of seat so gave it a damp clean- few scratches on foot rests but other than that I am happy with it - The arm rests are not as green as they look -I took it as sun damage but perhaps someone swopped the tops - One thing I have noticed is new one hasn't got the solid feel of the old one. Not bad for just under half price. Old one is a HAG Credo and new one is a HAG SoFi highback.
