Blue office computer chair with armrest

We are selling a good condition (no tears in fabric, etc.) with side arm rest to reduce strain. It is from a pet and smoke free home. There is a lever on the side to increase/decrease the height and there two knobs for adjusting (see ad pictures). The seat cushion is 17x18inches. The back cushion is 14x15 inches. The five casters “lock” to reduce the chair motion when no one is sitting on it. We are selling due to downsizing and delivery might be possible. Contact with a reasonable price offer to buy. If you need delivery, also mention the address.
