Even my NASCAR mechanic friend was impressed by the engineering of this bed. The bed looks great, performs (lifts for storage) great, and sleeps great. I had help assembling it, and it took about an hour to an hour and a half at a leisurely pace. The directions are easy to follow; no vague pictograms. I definitely recommend using a ratchet set with an allen wrench attachment. The nuts, bolts, and washers are clearly marked; no guessing which is part W or part X. The only downside: the hardware kit shorted us two bolts (but not washers or nuts), but we were able to make do safely. This is a beautiful bed which is practical and comfortable!
