The framework itself was beautiful when you opened it up. The only thing you had to do was attached to legs. As far as working it operates beautifully. We love it since the day we put it in we went with a 14 inch mattress on top of it because we wanted a little bit more cushion with the foam and it raised the bed up about 2 1/2 inches so it was easier for us at our age to slide out of bed instead of sitting up and standing up overall very good quality for the purchase.
