This bed comes mostly assembled and, except for some bolts, is made up of high quality materials. Be careful not to over-tighten the bolts as they may shear like one of mine did. Although the provided wrench does not have a long moment arm I was able to shear the head off the bolt by applying more than necessary pressure. I replaced those bolts with higher strength steel bolts I obtained from Ace Hardware. The matress is extremely confortable for a folding bed and this item is priced very reasonable for one of this high quality. I would highly recommend this item if you need a fold away bed.
