Prepare the work area, collecting the necessary tools and working on a carpeted surface to prevent damage to the bed or floor during assembly. Have an assistant help and don't hesitate to call an IKEA retailer for support if necessary.
Screw the legs of the bed onto each end of the side pieces, using the included hexagon wrench.
Insert screws into the appropriate holes of the headboard but leave enough of the screw exposed to form a short peg. Lock the screw heads into the notches at either end of the side pieces to form the rectangular frame. Tighten the screws after assembly. Repeat with the foot board.
Screw the rails to the inside of the side frames. These will support the mattress: Choose the lower row of holes for a lower position or the higher row for a higher-riding mattress.
Screw the supporting brackets into the center base of both headboard and foot board. Screw one end of each diagonal support into the corner of one of the brackets and attach the other end to the side rail. Choose an appropriately located hole on the rail to prevent bulging or pinching the frame. Set the keel into the bracket slots to complete frame construction.
Add any extra supports included on your model. Place the mattress on the bed and attach any other included parts.
