These stools are fantastic!  After sitting on square thrush seat stools for two decades, it was time for an updgrade.  These checked all the boxes....padded seats for our middle aged bums, swivel seat so we can linger and not miss any action, adjustable height seat so everyone gets a personalized experience!  Easily assembled, and easy to clean.  The bottom is sturdy on our uneven slate floors.  We purchased 2 sets over 2 years ago and they are holding up well.  Good value! Thanks Wayfair!
