Surprisingly sturdy and well made for such a good price. I added a few more slats that we had from a previous dismantled bed and also made the centre leg underneath the bed a bit more substantial in case you move the bed at all without lifting it as dragging will break it.  I like the fact that you can sit on the end of the bed when getting dressed as the frame  is lower than the mattress and that you can sit on the end of the bed  This is the second one we have bought and very happy. I recommend you also  buy the 1500 pocket sprung mattress which is fantastic too.
