Seems good so far! I was very weary of sitting on it at first, because it did seem like it's just going to break. I've had it for about a week or 2 now, and it's doing okay. There are some bits I'm not happy with, such as the bit in the picture which keeps tearing at my pillow 
But it's good enough for the price

UPDATE:
Had this bed for a few months now. It's very good for the price. Even the pull out part. Only annoying thing is the wooden panels beneath the mattress keep falling down, and are very hard to put back in.
