Yeah I bought a new computer chair recently (a few weeks ago). My old chair's back partly broke and the adjustment tools kept slipping.

I went for an Aeron chair, super expensive and a major investment but since I spend so much time in front of the computer, I needed a reliable chair that would be both relaxing and treat my body properly over long periods. This one has a 20 year warranty. Like a bed, you need to get one that is suitable for being within for extended periods or else you end up with muscle issues such as sore backs. Unless you only spend short periods in front of computer.

It took over 2 months for the chair to arrive after ordering.
