Construction seems sturdy and all parts were there but the adjustable cylinder leaks down while sitting on it requiring it to be raised throughout the day.
I purchased this chair after using my dining room chair for a couple months during COVID-19. It was easy to assemble and fits its purpose. I sit in it 8-10 hours/day and don't really get uncomfortable. I loosened the reclining resistance so I can lean back easily. One wish I had for it was if it could lock in the reclining position. Otherwise it is well worth the price.
