Our family is quite disappointed with the quality of the chair. The item finally arrived 1.5 months after the order, we were very excited upon receiving the chair. First we realized one of the rolling leg is missing. The chair felt to be very firm on the first day, however after 2 days of seating, we started to notice the significant dent in the middle of the seat. Our family member having back pain issue was hoping this to be chair with firm support. This item unfortunately does not meet the quality expectation that we hope for. Not sure if there is anything that your company can compensate from your end. Thank you.
