I bought these in black a few years ago and loved them.  Glad that I was able to find them again.  Had to order gray this time, because black wasn't available, but still a great product for the price.  I love the height on these and they age well without noticeable fading.  Definitely not apparent that they are plastic unless you are looking really closely.  I like the weight of the plastic so I can move them or rotate them without using a dolly.
