Assembly took about 2 1/2 hours, instructions were straightforward, the one Allen wrench kinda slows it down so if you have a spare use it or a drill with a bit. Came with one small incision in the upholstery but that wasn’t a big deal for us. Didn’t lose any parts but it comes with extra just in case. Really sturdy once we put it together, makes no noise with the storage bins on carpet. Great purchase!
