While these stools look great, were easy to assemble, and initially were quite comfortable, after two weeks of being sat on at meals by small (light weight) children and occasionally an adult, the 4 bolts used to secure the seat to the stool started to push through the padding of the seat, making them VERY uncomfortable - essentially un-sitable.  
Wayfair was great about issuing a store credit and we will try again with a different model of stools.
