Tempted to give it 4 stars because of how hard they are to open and even had to post for help but if you are having that problem, it turns out that once they sit in your house for a couple yours and get warm, you can then open them or use a very heavy arm.  I could not open mine at all when I took out of the box.  An or so later one opened right up.  I just opened the other 3.  One was still difficult but I kept at it and it opened.  I must say, they are really comfy and I needed them for a Dec 19th dinner and I'm more than pleased with them - now that they are open

Pros: comfortable
Cons: difficult to open at first
