I review office chairs as part of my job - I've been doing it for years. I particularly look for great ergonomic chairs – ones that help out your posture and support your lower back. And right now, my favourite budget ergonomic office chair – the Sihoo M90D - has had $130 whipped off its price for Black Friday. It's down from $299.99 to £169.99 over at Sihoo. If you're looking for a cheap-yet-quality-chair, you should definitely check it out.
When I reviewed the Sihoo M90D, I tested it for a period of several weeks. That's why I selected it as the second best office chair for back pain that you can buy right now. It is a perfect combination of solid ergonomics and low price tag. Lower that already low price to $169.99, and you've got an almighty Black Friday deal.
