Customers are mixed about the comfort of the office chair. Some mention that the knee pads feel fine, while others say that the seat's foam is way too soft.

However, some say that when in this chair or it becomes quite uncomfortable, the knee pad is not very comfortable, and that the ergonomics of the chair are not great.

Solution for lower back pain- perfect for people with desk job

Solution for lower back pain- perfect for people with desk job
Work at a computer all day long and play racquetball. The sport forces a crouching serve position where the back gets stressed as well. I got the chair for my lower back pain. It replaced a highback executive chair. Has worked wonders for my lower back and I have not used my old chair for about 2+ months.Lack of the support in the back forces the posture to be self supporting. I can sit with my legs tucked in below the chair or spread in front of it (see pictures). Don't think I will ever use a regular chair for computer work.A colleague got it as well. She has bad knees and has some knee pain on using the chair (sometimes). The chair is easy to aseemble. Raising the adjustable seat height could be a pain but I haven't need to fiddle with it much. Given the lack of restraints on the back or sides, I can perform streches while sitting on it. That was a bonus! Highly recommended if you work on a computer and have lower back pain.
