I was able to set it up very quickly and by myself without any trouble. A couple of the plastic feet that insert into the metal were crunched, but I was able to get the replacement within the week. 

On the king size I was worried about the middle being supported, so I created my own middle support which was extremely easy to attach through the spots that the legs attach to. 

I love that I never have to worry about banging my shins on the corner of my bed frame again. Such a great buy for the price. Especially since I still rent and the Ikea frame I had before just deteriorated each time I moved.
