Easy setup, super sturdy. And storage!!!!

I love this bedframe. I purposely wanted something that looked like I could put it together myself and I was not disappointed. Once you pull the frames out of the box, you just unfold them, lock the legs in place, then attach them together with the included bolts and wing nuts. The frame is so sturdy, yet it's easy to move when I change the sheets. So happy with this purchase. Oh - and storage! There is so much stuff I can put under the bed now. It really helps sincce my closet space is seriously lacking
