Chairs look good but.. one had holes misalign and could not be assembled. (Still waiting for a reply from company.)
The one chair that could be fully assemble is too stiff to swivel. (The actual reason for the purchase). The swivel assembly is plastic, unlike previous chairs I’ve had that are metal. I’m sure over time the plastic will loosen or crack, maybe then it will swivel.. 
Not sure if they are worth the money.
