This chair looks very stylish and elegant addition to our office room. First of all, easy to assemble - instructions were clear, all parts were included. Assembly was straightforward taking under an hour me to assemble it. Extra wheels are provided. The movement is very smooth and it's a very good addition to our home office. Chair is strongly built, firm to sit on. Very comfortable, the plastic running across the back of the chair serves as lumbar support. Though, I imagine if you have back issues it might not be enough. The chair can be adjusted for a range of heights. Design is sleek, well thought out, no unnecessary decorations etc. , just what I was looking for. Highly recommended.
