These chairs are really a great bargain. I run a lab operation and was looking for a chair that would allow our employees (including myself) to sit for long periods at the lab benches and be comfortable. 

The padding is adequate, the adjustable range is excellent, and if you go with the non-fabric, they are resistant to minor spills. The assembly is easy and only takes minutes.

These chairs aren't quite as good as Steelcase commercial quality, but overall, I'd highly recommend them as a great option for the budget conscious shopper looking to get a task chair for laboratory use(or probably drafting chair).
