We were excited to receive these chairs. They took an hour or so to put together. 2 parts were missing, 1 nut cap and 1 screw cap. I was able to find substitutes at our local hardware store.
The chairs LOOK nice, but unfortunately that is where the positive review ends. The first day we had them outside they got wet, so they sat in the sun and dried, only they didn't dry. There is some sort of thin foam between the 'waterproof fabric' layers that never dries, despite being in the sun for hours, and even days. 
Terrible design! We can never sit on them without getting wet.
