purchased these cause our current stools don't have a back and we wanted one for our kids.  i would describe the quality as about average, and curious to see how they hold up to kids.  the kids like them and find them comfortable.  the back is not very high, so don't expect to lean back if you are an adult.  they seem to be less comfortable the bigger you are (height and weight).  our previous stools (also from wayfair) had all 4 legs welded together, while these are 4 independent legs that you screw together, making "wobble" a bit more likely.  although they do come with levelers on the leg bottoms.
