I work 60 hours per week at home, that means I'm probably seated for 58 of those 60 hours. I always used cheap chairs because I'm a cheap guy, I guess I'm pretty lucky because I've never felt pain in my back, but I am getting older now and I realised maybe it's time I invest a small amount on a computer chair since I sit 58 hours a week in it, I searched online and I found a Markus swivel chair, it cost around 200$ CAD, it's not a Herman Miller but it's not too bad. I read some reviews and people said it's the "cheap" chair of high-class chairs. I've been using it for a month now and I love it!
