I work in front of the computer all day so I needed a cushiony but affordable desk chair with seat height adjustment to WFH. This chair was very easy to assemble and I decided to leave the arms off so the chair can fit easily under my desk. You could definitely assemble with the arms on or off if you prefer. The casters do not lock which is not a big deal for me since the chair is on carpet. For the price and quality I would recommend this chair.
