We replaced multiple wooden chairs with these beauties. 
They look great! comfortable, durable vinyl material, easy to assemble and clean, and a great price for a set of 2.

They advertise to be stackable, but no recommendations how many can be stacked. We found you can stack 2 safely, 3 would be the maximum height, but it is not our recommendation due to possible damage to the material. 

With as many chairs as we have, we were hoping to find a transport dolly to move these to different areas. This would have been a great suggestion on the site page from the company. 
Overall, it was a great buy.
