Amazon カスタマー 4 The chair is very well packaged, and easy to assemble. Clear instructions, and has a very premium quality to it.The chair itself is a bit firmer than I was expecting, but overall is pretty comfortable. You can adjust just about anything from the arms to the build in lumbar support. The magnetic head pillow is much softer than I was expecting, and a nice surprise.I saw on other places ppl complain about a lot of noise coming from the lumbar support and the cushion, but I have had no noise issues with my chair yet.Overall, its a great chair, just be aware it is not a soft chair. Its very firm, so if your looking for something softer, be careful.Also be careful that the chair comes in 3 sizes. S,R,XL. I am 182 cm 80 kg and the R size is the perfect size for me.
