How to Build a Simple Platform Bed Frame

Building a platform bed frame is a relatively easy project that can be completed in a few hours. The most important part of the frame is the nine support legs, which must be very sturdy to support the mattress and foundation.

Begin by cutting the 2×6 and 2×4 lumber to the desired dimensions. The bed frame will be approximately 74″ wide by 54″ long, but you can adjust these dimensions as needed. Next, drill nine holes in each of the 2×6 lumber pieces, using a 3/8″ drill bit. These holes will accommodate the threaded galvanized pipe nipples, which will act as the support legs.

Next, assemble the frame by connecting the 2×6 lumber pieces with the threaded galvanized pipe nipples. Be sure to use a T-bar wrench to tighten each nipple securely into place. Once the frame is assembled, attach the floor flanges to the bottom of each of the support legs. This will create a stable base for the frame.

Now it’s time to attach the headboard and footboard to the head and foot of the bed frame. If you’re not using a headboard and footboard, you can skip this step. Simply use 4″ wood screws to attach the headboard and footboard to the frame.

That’s it! Your platform bed frame is now complete. Add your mattress and foundation, and enjoy a comfortable night’s sleep.

Project Basics

 

Building a DIY platform bed frame is a great way to save money and customize your bedroom furniture. The project can be adapted to different bed sizes, and the height of the bed frame is adjustable. All you need are a few basic tools and supplies.

To build the frame, start by cutting a rectangular piece of lumber to fit the overall dimensions of a standard queen-size bed. Next, attach three long leg supports beneath the frame. Then, install nine legs made of galvanized pipes. Finally, cut and install six cross-slats across the frame.

The height of the bed frame can be adjusted by choosing different-length galvanized pipe nipples for the legs. Threaded nipples can also be purchased in different lengths if you choose a different bed height.

Tip

For a more industrial look, you can use black iron pipes and floor flanges for the leg. Black pipe is normally used for gas line connections, but is sold in the same area of the store where other plumbing supplies are stocked.

Instructions

 

01- Cut the Frame Boards

With a power miter saw or circular saw, cut the 2×6 lumber to produce the following pieces:

Two 80-inch-long boards for the sides of the frame

Two 63-inch long boards for the end pieces (head and foot) of the frame

Three 83-inch-long boards for the leg supports

Note: These sizes will produce a frame for a queen-size box spring and mattress. You’ll need to adjust the dimensions if you are building for a different bed size.

To cut the frame boards, use a power miter saw or circular saw to cut the 2×6 lumber into the following pieces:

– Two 80-inch-long boards for the sides of the frame

– Two 63-inch long boards for the end pieces (head and foot) of the frame

– Three 83-inch-long boards for the leg supports

Note: These sizes will produce a frame for a queen-size box spring and mattress. You’ll need to adjust the dimensions if you are building for a different bed size.

When cutting the lumber, take care to make precise, straight cuts so that the frame pieces fit together properly. If necessary, use a guide or straightedge to help keep the saw blade on track. Once all of the pieces are cut, sand any rough edges before assembly.

 

02- Test-Fit the Frame Boards

 

To test the fit of the frame boards, have a helper hold the boards in place. Mark the locations of the screw holes on the end frame pieces. Drill pilot holes for the screws at these marks. Drive screws through the end frame pieces and into the frame boards. Make sure everything is square before driving all of the screws in.

If everything fits well and is square, remove the screws and proceed to the next step. If not, make the necessary adjustments and test again until the frame is perfect.

Tip

Once assembled, this frame will not be easy to move, so it’s best to assemble it in the room that will contain the bed.

 

03- Screw the Outer Frame Together

Attach the head and foot frame boards to the side boards with screws, making sure they are flush at the corners. Use three screws at each joint.

This will complete the outer frame of your bed. Proceed to the next step to add support boards.

 

Tip

Drill a pilot hole for each screw to avoid cracking the wood.

 

04- Test-Fit the Leg Supports

Test-fitting the leg supports is important to make sure they are the correct length and fit flush against the frame. It’s also a good time to make any small adjustments before screwing them in place.

Lay the three 83-inch leg support boards on the flat, lengthwise across the frame—one at each side and one directly in the center. The ends of these leg supports should be flush with the outside edges of the end boards, with no overhang.

The left and right leg support boards should fit flush to the outside edges of the side frame boards. Because they are laid flat, these left and right leg supports will overhang the side frame boards on the inside by about 4 inches.

Once you have the leg supports test-fit, you can screw them into place. Be sure to use screws that are long enough to go through the frame boards and into the leg supports.

Counterbore the holes on the outside of the frame so the heads of the screws are flush, then add washers and tighten. On the inside of the frame, predrill and countersink the holes, then add washers and screws. You may want to use a clamp to hold things in place while you’re screwing them together.

05- Attach the Leg Supports

Attach the three leg supports to the frame with 2 1/2-inch screws. For the two side leg supports, use several screws spaced about every 12 inches along the length of the boards, driving them down into the frame below. The center leg support is attached to the frame only at the ends. This will give your table extra support and stability.

06- Attach the Floor Flanges

Attach the floor flanges to the bottom of the bed frame using the cordless drill and 1-inch screws. Make sure to evenly space them out, with three on each leg support. Each flange will receive four screws. This will ensure that the frame is sturdy and can support the weight of the mattress and any person who may sleep on it. Thanks to the flanges, the frame will also be level with the ground, ensuring a comfortable sleeping experience.

Tip

Experiment with the placement of the two flanges at the foot of the bed frame. Placing them slightly closer toward the head will disguise them. Placing them closer to the foot will expose them and emphasize the industrial look.

07- Complete the Legs

Install pipe nipples into flanges. This can be done by hand, but using a wrench or channel-lock pliers may be necessary for a tight fit.

Turn the bed over and position it where you want it in the room. This is best done with help, as the frame will now be quite heavy.

Tip

For a true platform bed, you may want to omit the box spring altogether, resting the mattress directly on the slats. If so, you may need some additional support by using more cross-slats—perhaps as many as 10 or 12. Another option is to cut a piece of 3/4-inch-thick plywood to lay directly on the leg support boards.

08- Cut and Fit the Cross-Slats

Cut six 2×4 boards to 59 3/4 inches. Space these cross-slates equally across the bed frame so they rest on the leg support boards. Make sure that the two end slats are at the very head and foot of the bed, which will ensure the box spring is well supported.

To cut the cross-slats, first measure and mark the boards at 59 3/4 inches. Then, using a saw, cut along the marked line. To ensure that the slats are spaced evenly, start by attaching the two end slats at the head and foot of the bed. Then, space the remaining four slats evenly in between. Make sure that each slat is resting on a leg support board before attaching it to the frame.

To attach the cross-slats, use screws or nails. For added stability, you can also use L-brackets to join the slats to the leg support boards. Start by attaching the end slats, then work your way in towards the middle. Once all the slats are in place, your bed frame is complete!

09- Attach the Cross-Slats

Secure each cross slat to the leg supports using a single 2-inch screw driven at each end. This will ensure that your slats are evenly spaced and securely attached to the frame. Cross slats should be evenly spaced so that they can provide adequate support for the mattress and weight of the sleeper. You may want to measure and mark the location of each cross slat before attaching them to the frame. This will help you to ensure that they are all attached in the correct position. Be sure to use screws that are long enough to go through both the cross slat and the leg support, but not so long that they protrude out from the other side. Once all of the cross slats are attached, your bed frame is complete!
