Easy to assemble, however it took me a second to figure out because the instructions had a few different beds on them. Each bed had a number associated, I didn't know which number my bed was. The zoomed in diagrams with screws were a little wonky, but I eventually figured it out. The bed is extremely sturdy. I got a queen so it has a crossbar, making it surprisingly sturdy. It doesn't budge when I hop on there.
