We got the black one because the grey stools are out of stock. 
The stools looks cool. However, one of the stools is missing one bottom base of the legs and one of the bottom base if not fitting the legs properly. We reached out to Wayfair on 06/16, The CSR replied on 06/18 and asked us about the part number. BTW, no instruction and NO booklet nor part numbers inside the boxes. We replied with pictures right away. it is 06/28 today, No replies from Wayfair. 
this is the first time we use wayfair and will be the last time unfortunately.
