These chairs were so easy to assemble, look great and I am thrilled with them.
They are substantial enough to be sturdy, but not overly heavy and cumbersome.  

I can't say how well they will last over time as I just put them together, and am getting ready to Scotchguard them before using them as we have 3 grandchildren that will be using them a lot too, but the fabric is thick enough, and the construction seems strong enough, to hold up to a lot of use.
