Durable, but incredibly heavy. If you don't have to move them far it's okay, but I have to take them a long ways in the fall, to make way for snow. I'm strong, but I can say, they are heavy and awkward to carry. 
Another reason for the 3 stars is that while most Adirondack chairs slant back too far for my liking, these are almost too uptight.
They're fine but I'd probably get a different chair if I could do it over.
