Easy to assemble. Requires at least 2 people. The box is over 300lbs. Headboard is very heavy and contains all the assembly pieces including side rails and footboard under the Velcro backing as seen when you first open the box. Unpack all the contents from the headboard first before moving the headboard out of the box. My 13 year old helped me move the box with a dolly. My 12 year old helped me assemble it. Side rails are in 2 pieces and connected by a thin bracket so they are not very stiff after assembly as a side rail should be. One of the frame base boards had a predrilled hole that was smaller than all the others so we couldn’t attach that side to the side rails. Other than that, it’s a solid piece especially for the price.
