These stools look even better in person than in the picture.  They seem sturdier than expected, and the seat is thicker than it looks in the picture, so that is a plus for me.  I've only had them a week, so I can't speak to their sustainabilitiy, but so far I'm very happy with this purchase.  I've looked all over for stools, and for this price, these were a great find!  
Assemby was very easy and they come with real wood plugs for the screw holes, which makes them look even nicer.
