I’m a chronic sloucher and for years, I used a terrible, old, tattered desk chair that was about to be thrown away at my last full-time job. That didn’t help my crouching issues, and after long periods of sitting, I ended up with plenty of cramps in my neck and shoulders, and back.
Ergonomic chairs like ProtoArc’s EC100 Ergonomic Mesh Office Chair are supposed to fix slouching for good and prevent us from experiencing all those aches and pains. That’s largely achieved by supporting your lumbar spine using a dedicated panel that protrudes into your lower back. The EC100 indeed has this panel, though surprisingly, it doesn’t feature manual adjustment.
