Awesome bed and super sturdy. I bought a queen bed frame with a 11" Casper mattress. The mattress is just high enough so that my pillows won't slip under the bed frame but you can still see the headboard which is great.  I also really appreciate that the middle bed frame support is metal so its super sturdy. I toss and turn a lot at night and have yet to hear a noise from the bed frame. Very easy to assemble.
