These look beautiful and were very easy to put together. I managed it in 20 mins (for 2) while watching tv.  Only reason I am not giving 5 stars is the perspex back on one stool was a little scratched on arrival. I ordered 2 more in the same colour immediately to finish off the counter set. The seat pads are very comfortable and the swivel is great. I'm not sure the seat back could take anyone very heavy leaning back in them however.

Update 4 weeks later: The stools are working out great. Very comfortable to sit in due to the padded seat and swivel (no dragging them across the floor to get on or off them) My only bugbears are that the clear back shows fingerprints all the time and also crumbs get trapped down the backs of the seats and can be seen through the clear back. Neither are a huge deal, the prints wipe off easily, and at least I can clearly see the crumbs to vacuum them out once a week.
