It was easy to assymble (did it alone). It took me about an hour and a half. Once you get orientated, you assymble the changing table first which is what takes all the time. Once it’s together it’s about 25 minutes for the rest of the crib (if you don’t use power tools). All in all it’s great and works well for us.
Edit: It’s been 14 months and this thing is holding up like a champ, not a single Actual problem so far. We did notice that during the first stages of teeth’s my kid would try to bite/chew on the crib. The paint started to come off which led us to be worried but it ingestion but it’s never got bad. Just small spots here and there.
