Just put it together yesterday so I cant comment on longevity but it seems well made. Id estimate 4 hours for one person to assemble including sorting all parts first - hard to say as I had kids helping and stopped for dinner etc. the only time I truly needed help was putting the top bed up. Its a big job (as expected) but instructions were clear and everything is labeled. It says not to use power tools but I did for attaching the mattress support slats as that would have taken forever without - no issues but just be mindful and dont overtighten.
Two minor complaints- the stairs are particle board and the corners are sharp. I anticipate someone whacking a shin. Also the mattresses dont fit tightly (standard twin mattresses - different brands). I may try to put a pool noodle in the gap so every toy that comes to bed doesnt get lost.
Perfect for our needs
