Does anyone have recommendations for good office chairs with ergonomic design and lumbar support? My budget's around $400. $100+ types are a nono - I get a bad upper-back ache using these, and they just aren't durable, prob because I'm heavy at around 80+kg.
Ikea and courts do sell some, but I'm not sure if those are ergonomically designed. Any bros know of any company that specialises in this, or any particular brand(s) that you would recommend? Thanks for your help!
