Haworth Fern Ergonomic Office Chair Without Lumbar Support, Adjustable Desk Computer Chair with Breathable Mesh Finish for Home Office Furniture, Coal

I've spent a considerable amount of time in my recently purchased chair (acquired in December 2023). The chair is sturdy, but, honestly, sitting in it for extended periods has become a source of stress for me. Before using this chair, my back pain was infrequent and manageable. Now, I experience a tense, stressed feeling in my back when sitting in it for less than 8 periods with a standup desk. Interestingly, when I return to the office and use a Steelcase chair, I don't feel any back pain, even after prolonged periods of sitting. My focus remains solely on work without experiencing any tension. Considering my personal experience, especially given my weight (168 lbs), I would hesitate to recommend this chair for those who tend to feel tense or stressed during prolonged sitting. It might not be the suitable choice for everyone's back, even for those with minor back issues. Particularly after using my office chair (Steelcase), I can confidently state that something seems amiss with the cushion. I feel as though I've purchased back pain and back issues with $1100+ chair.
