Easy to assemble and has survived with me through 2 moves already. There are only five slats that come along with it and I haven't needed anymore. The legs that come on the slats are made of plastic and are adjustable and are prone to breaking if you do not adjust them correctly.
I have a regular king-sized mattress and I did notice that I have a few inches of extra room on the sides where the slats are visible. I thought that maybe the frame was made for a California King then remembered that it wouldn't have mattered because Cal Kings are just longer mattresses, not wider ones. It's not a big deal for me since the comforter covers it, but it can be a bit annoying when you have to straighten it out.
Gorgeous and very modern bed!
