I researched poly/resin chairs for hours before finding these.  These are a great alternative to much more expensive chairs, and the quality appears to be comparable to chairs that are twice as expensive.  Assembly takes about 20-30 minutes each, which isn't too bad.  One small complaint...the hardware that it comes with is silver (not painted black), which detracts from the overall sleek design.  I spent a few minutes applying black touchup paint to the screw heads, and fixed the problem.
