I'm not practical at all but it came with good instructions and all the tools so job done in 20 minutes.The build quality is good, all the main support frames in cast aluminium.The mesh material is really high quality, soft to the touch and breathable.This chair is 'very heavy!'...feels quality.When I first used the chair it was 'OK'.....comfortable but not quite as good as expected, "however" I realised the points of articulation on the chair are mind blowing so I set about making adjustments to fit me. The seat slid forwards giving more depth. the back raised up and the lumbar support adjusted forwards. Even the arms adjusted in every way imaginable. The bottom line is that after taking the time to set the chair up properly to my proportions it felt great, very comfortable and very supportive. Love it!All in all, a good purchase and I'm very happy with my choice. ### ⭐⭐⭐⭐⭐ Amazing Chair highly recommend *by U*** on 19 September 2024* I recently purchased the Sihoo S300 chair from Amazon, and I couldn't be happier with my decision! From the moment I started assembling it, I could tell it was a high-quality product. The instructions were clear, and all the parts fit together perfectly.Once set up, the chair exceeded my expectations in terms of comfort and support. The adjustable lumbar support and headrest make long hours of sitting incredibly comfortable, especially during work-from-home days. I love how I can customize the tilt, height, and recline to fit my exact preferences. The mesh back is breathable and keeps me cool even during extended use.In terms of design, the Sihoo S300 is sleek and modern, fitting well in my home office. It feels sturdy and durable, even after weeks of daily use. For anyone looking for an ergonomic chair that offers great value for the price, this one is a fantastic choice! Highly recommended! ### ⭐⭐⭐⭐⭐ One of the best customer service experiance (SIHOO) *by D***D on 24 November 2024* After purhasing a product we tend to forget the importance of customer servervice unless there is a need.I have been incntact with SIHOO and I have to say I have been pleased with the customer servece.
