Already, it was delivered with gray decorative plastic and rubber damaged right handle to lever torn cylinder. Contacted, the seller said not being able to procure the parts but made a gesture of goodwill by 15%. To his credit. As against the chair is not solid. I had one (another brand) that lasted me over 13 years, it may not take one year. He was marked for a maximum weight of 140 kg, I make 100 suddenly I had opted for the former. I use it every day, several hours a day. He soon began to lean left. Why, I do not know. everything is screwed but the mechanism had to distort ... the inclination is visible by eye and must be 2-3 cm. It feels when sitting and it is rather unpleasant. I am rather disappointed for once.
