Maybe we assembled it wrong but the chair doesn’t raise very high. Other than that it’s a nice desk chair. Update 8222020 well the chair is falling apart after retightening the screws constantly it makes a sound that to me predicts it’s moments away from breaking. To be fair it was for my son who us over six feet tall and 200lbs. We are probably pushing our luck with the weight requirement. We purchased a chair for a taller person and this is going to goodwill.
