I bought 8 total of these a month ago, still waiting on 2 to arrive but I will review the 6 I do have. 

Nice curved back which cups your back and is actually comfortable. I was looking for modern but affordable. These fit the bill. 

The seat is a black vinyl which I was hesitant about but actually appears to be a medium weight vinyl not a thin one so should hold up ok. 

The reason for the 3 stars is that all the chairs get wiggly and need to be re-tightened using that awful allen wrench. 

We have 4 people 2 who are young children using these chairs 2-3 times a days for the last 2-3 weeks and I have had to re-tighten the chairs twice now. REALLY?????? 

I know they are inexpensive but that sucks. Otherwise super cute and not tiny tiny and child friendly with that wipe it clean vinyl.

Pros: more affordable modern wipe clean vinyl seats
Cons: need to be re-tightened often
