The bed wasn't as hard as I thought it would be the directions were somewhat simple. However, following the directions step by step still took me about 4 hours to put together, but I had nothing left over. I did go back over the screws to tighten it up but it still feels a little unsturdy. I only encourage my 7 y.o. to sleep on the top bunk , but the 14 y.o. has too. It didn't give a weight limit for the top bunk which bothers me. If you know or find out it would be nice.
