They are great for a temporary furniture piece or area not used too much. I am petite, and they sink down a bit when I sit on them, so they may not be best for heavier people. Also, the rubber beneath the base fell off within the first few months. I got them in white, and they are easy to clean and great looking, nonetheless!  

Pros: Design, easy to clean, easy to use
Cons: Adjustable height is sensitive, not long term/high use quality.
