Home - Diy How to Assemble a Metal Bed Frame By Laurie Brenner Updated July 17, 2017

Each metal bed frame, based on type, has its own assembly method. Once you unpack the frame to see how it fits together, assembly goes quickly.

Metal bed frames with headboards and foot boards are the easiest to assemble.

Metal bed frames come in all shapes, styles and types. An adjustable bed frame, the most common frame used for twins, full beds, queens and kings goes together fairly simply once you lay out the two side L-angled rails and unfold the horizontal support bars. Some bed frames may have a center support that runs vertically the length of the bed that attaches to the supports that fold out from the side rails.

All you need are some common household tools to assemble the bed frame before adding the box spring and mattress.

Gather the tools needed before you begin. All you'll need is an adjustable wrench and tape measure.

Warning

If you have a hardwood floor, assemble the bed frame on a blanket to avoid scratching the floor during setup.

Measure the Bed

1. Measure the width of the box spring, as this is the part of the bed that fits inside the metal bed frame. Write down the measurement.

Lay Out the Pieces

2. • Lay the L-shaped side rails on the floor near the area where you want to set up the bed, with the bracketed ends at the top of the frame for the headboard.
   • Unfold the support bars from the side rail at 90-degree angles to the side rails.
   • You should also have four or more coasters or glides that attach to the frame as feet. Look for two L-shaped plastic end caps that slide on the end of the side rails at the foot of the bed.
   • For the keyhole-type frame, lay the expander bars at the head and the foot of the bed after unfolding the supports.

Secure the Supports

3. • Slide the piece that has a wing-nut fastener on each arm of the "E" on the left side, if that is the type of bed frame you have, and lay the support from the right side over the left side bar support.
   • Slide the fastener over both bars and tighten loosely to hold them together, repeating for each horizontal support.
   • On the keyhole bed frame, set the small expander bar of the two bars that protrude from the side rails and the center support bar at the top and bottom of the frame, aligning them by the holes in the frame based on the box spring width.
   • Set the bolts or the pins in the bars through the holes so that the two sides and the center support are connected.
   • Lightly fasten the nuts on these to keep them in place if they have them or slide the bar to lock the pins in the holes.

Measure the Frame's Width

4. • Measure the distance between the angled L-shaped side rails to match it to the box spring's width, adjusting the distance between them as needed to fit the box spring measurement.
   • Tighten the slide bracket’s wing nut when the measurement is correct.
   • Repeat for each of the support arms.
   • For the center support frame, once the width measurement is accurate, tighten the nuts onto the bolts with the wrench if included.

Attach the Headboard

5. • Attach the headboard, if you have one, to the metal frame securing it by inserting the bolts through the brackets and through the holes in the headboard.
   • Add the washer and nuts on the opposite side of the headboard so that they face the wall, and tighten.
   • Repeat for each hole, bolt and nut that goes into the bracket.

Tip

Metal bed frames with separate headboard and foot boards usually have slots in them to set the side rails into, which may or may not be secured by bolts and nuts, depending on the type. The center supports for these beds are usually secured to the side rails via bolts and nuts you tighten, or they may have a pin that slides into a hole to keep them in place.

The Drip Cap

• Metal bed frames come in all shapes, styles and types.
• Write down the measurement.
• • Lay the L-shaped side rails on the floor near the area where you want to set up the bed, with the bracketed ends at the top of the frame for the headboard. * Unfold the support bars from the side rail at 90-degree angles to the side rails. * You should also have four or more coasters or glides that attach to the frame as feet.
