I bought a boules mesh chair as I work from home and I wanted a decent chair (actually, my wife wanted to throw out my old chair as it was very grubby), and it was without doubt the worst chair I had ever sat on, no idea who it was moddled on but it was terrible. So we contacted them back, they sent a cushion, and that didn't cut it. So we wrote back and they said I could swap for a different chair, so I swapped for a Master chair, which was also on sale at the time and it is the most comfortable chair I have had. I never worked out how one company could produce two so totally different chairs! Anyway, that one is fantastic
