First off the chairs are super dope and comfy. The zero gravity is fun however the locks don’t work super well. In other words you’ll lean back and lock in the angle and after a bit the locks don’t work and the chair starts moving back. 
The worst part and why I’ve giving it 2 stars is the fricken cup holders tray thing break when you unfold the chairs. This happened on first couple days and I thought maybe I’m just an idiot but nope friend of mine broke the other one a few days later. Not sure maybe they are designed to take of the tray thing after folding seems a silly.
