Easy build and the kids love them. Definitely worth the $ (though awesome wayfair price) to transition to these from crib vs straight to twin beds. We have twins and this helps define their space yet not take over a room. Plus for potty training we wanted to stay with crib mattress. Same sheets even! 
Dropped a star due to paint. Bright blue beds are great but the color scuffs easily onto my light colored walls. Fixable and wouldn’t stop me from buying beds.
