Eliza Tinsley Ergonomic 24 Hour High Back Mesh Chair | Black | ERGO/KTAG/M

I bought this as we use them at work and they are quite comfortable and have good adjustability. Not the easiest to move around on a carpet while sitting in it but that's really a minor criticism.

Excellent quality.

I purchased one of these elsewhere, but I am very impressed with it and wanted to leave a brief review. As I write this, I am sat on the seat in question (working from home, due to Coronavirus) and have spent many hours in it already - more than I'd like! It is very supportive and very comfortable; possibly even more so than the expensive company-provided chair into office. You can adjust the height of the chair, arm rests and the head rest, but also adjust/lock the tilt of the backrest and also the amount of lumbar support provided. The cushion is firm, but in a supportive way, as opposed to that flimsy foamy stuff that does nothing after a couple of hours. The mesh of the chair is supportive, lightweight and lets the air flow through. It isn't the cheapest chair, but it certainly isn't wildly over-priced. When you consider how much time we spend at our desks, I'd suggest it's a worthwhile investment, both if your work, but most importantly your health.
