I am only 5’ tall, so the back support on the chair is in the middle of my back and the neck support is also too high. Nowhere did it mention the chair was suitable for people over a certain height, it says « fully adjustable ». On the other hand, it is very well made, good quality, cushion hard but getting used to it.

Great chair, amazing quality.

The chair is adjustable in so many ways and small details make a big difference. The concave arm rests are a wonderful touch. Highly recommended.
