Super comfortable

It was super easy to set up, feels very sturdy, and the lumbar support makes sitting for long hours so much easier on my back. Definitely worth every penny!

Very comfortable and helpful. I didn't think that a budget ergonomic chair could help me get rid of chronic lower back and abdomen pain that I had been suffering from for 2 years. I took a chance with a budget chair and it did. In two weeks, my pain went away. This wasn't the only thing, I adjusted my posture as well but this chair made a big impact.
