Would Not Recommend
In my opinion, I would not recommend the SIHOO chair. I found it pretty uncomfortable overall. The lumbar support, which is supposed to help support your back, was not as helpful or noticeable as I expected. It also does not seem adjustable unless you are pushing the backrest backward. The way it protrudes made it uncomfortable to sit with my back against the chair because it pushed my posture in a weird way, causing my head to lean backward instead of allowing me to sit upright naturally. The armrests were also frustrating because they move way too easily, even with the lightest touch. My experience with the return process has also been disappointing. After I returned the chair, customer service advised that the warehouse was unable to locate the return. As a result, I have not received my refund. From my perspective, the company now has both the chair and my money, and I am still waiting for this to be resolved. Based on my experience, I would not recommend this chair or this company.
