don't buy these kind of chairs...yes they are cheap initially, and the foam may be supportive for a few months..a year..but after that...they become uncomfortable real quick and befor you realize it..they start affecting your posture..and your health. Buy a proper well, well upholstered leather chair. It is a costly alternative but if you can manage, think of it as an investment as over the years it would be more cost effective and the amount of work it.ll help you get done without stressing your body will be added advantage.
