Got tired of having office chairs breaking after a year or so. They also leaned back too much, or the air piston would give out. Used a kit like this and some 2x4's, added paint and plush outdoor cushions, made my own 3 foot wide, and it's rated at 400 pounds capacity and works for me. I like what someone did with this one.
