Before You Build This

• Skill level: Beginner
• Tools required: Kreg Jig, Drill, Miter Saw, Sander, Brad Nailer (optional)
• Approximate build time: 8 hours
• Cost at time of build: $50 for lumber
• What I’d do differently today: Change up the color scheme and rip the rounded edges off the 2x boards.

Would I build this the same way today?

I built this bed in 2014 and have improved my skills over the last 12 years. If I were to build this bed again, I would change the color scheme on the headboard to one solid color for a more modern aesthetic and I would definitely rip the round edges off of the 2x boards for a more modern, clean look. Other than that, this is a solid bed that I sold in great condition a few years later to replace with a new design.

Building the DIY Platform Bed

I’m back to share the Easy DIY Platform Bed that I made for my son 🙂 If you missed the Free Plans for the Planked Headboard, go check them out! I saw a platform bed in a West Elm catalog and loved how chunky the base and platform were, so that was my inspiration and I built it for about $55!!!

How to Build a DIY Platform Bed Frame

Step 1 – Assemble the Bed Frame Base

I started by making all of my cuts for my top and bottom frame. You can find the cut list diagrams in the fee plans. Watch our How to Use a Miter Saw video HERE!

Then, I drilled all of my pocket holes with my Kreg Jig pocket hole jig set for 1 1/2″ thick boards. (You can find the Kreg Jig HERE on Amazon) and check out our How to Use a Kreg Jig Video HERE!

I attached the top frame with 2 1/2″ pocket hole screws and wood glue.

I followed up and did the same for the bottom frame.

Next, I flipped the top frame over and attached the bottom frame to the side rails with 2 1/2″ wood screws and wood glue.

Step 2 – Attach the Bed Frame Supports

I flipped it back over and attached the center support with 2 1/2″ pocket hole screws to the headboard and footboard. You may need help flipping the bed back over, at this point, because it is heavy.

Finally, I attached the 2×3 cleats, to the sides of the bed, with 2 1/2″ wood screws (I call for 2×2 in the plans because 2×3’s are not available in every region.  If you do use 2×2’s for the cleats, get furring strips to save money). I like to use the Spax self-tapping screws. I find them at Home Depot and they are pricey but you don’t need to pre-drill with them!  If you use regular wood screws, make sure to pre-drill first to prevent the wood from splitting.

Step 3 – Sanding and Finishing the Wood

After sanding the entire Platform Bed down, I applied one-coat of Rust-Oleum Dark Walnut Stain (you can find it HERE on Amazon). If you are buying your supplies at Home Depot, get the Varathane brand in Dark Walnut (it’s the same stain).

Step 4 – Install the Mattress Slats

When the bed was dry, I took it inside and into my little man’s room!  I used my brad nailer, with 1 1/4″ brad nails to attach the 1×3 slats.  I just spaced them out evenly and attached them to both cleats and the center support. You can use the cheap furring strips (douglas fir) for this part, Just make sure they are smooth so they don’t tear-up your mattress. Note: you can also use 1 1/4″ wood screws to attach the bed slats.

Step 5 – Attach the DIY Headboard

To attach the headboard to the bed, I drilled 2 1/2″ spax screws from the backside of the headboard legs into the bottom and top frames of the platform.

I just love this DIY Platform Bed so much! It’s the perfect combination of rustic and modern farmhouse and it’s so sturdy! I know my son loves it just as much. I’ve overheard him bragging to his friends (on a few occasions) that his mom built his bed – which is the best part for me 😉

Don’t forget to check out the headboard plans and if you like the wall color in his room (I’m obsessed!) you can read about it my wall color choices! I have received a lot of questions about the quilt on his bed, it is from Pottery Barn Teen but, I bought it a couple of years ago so I’m not sure that it is still available.

DIY Platform Bed FAQs

How much does it cost to build a platform bed?

The cost to build a platform bed can vary by design, materials used and current lumber prices. We typically build with framing lumber, like this platform bed design. We always share our supply list which makes it very easy to research the current lumber prices in your area to get an exact price on the cost to build your bed.

Is this project beginner friendly?

Yes! This is a great first build! The size might be intimidating but beds and dining tables can be the best first-time projects! They are straight forward and just a few steps and basic tools! Many of our readers have built beds from our plans as their first DIY build!

Can the dimensions be modified?

We always get questions on how to modify the measurments to fit other mattress dimensions. This DIY Bed Frame is easy to modify to fit any mattress size.

• Twin Size Mattress – Subtract 15″ from the width.
• Queen Size Mattress – Add 7″ to the width and 5″ to the length
• King Size Mattress – Add 23″ to the width and 5″ to the length.
• California King Size Mattress – Add 19″ to the width and 9″ to the length.

What tools are absolutely required?

The only tools you must have are a miter saw (a hand saw and miter box would work as well as a circular saw), a drill and a Kreg Jig!

What size mattress fits this DIY bed frame?

This bed frame was designed and built to fit a full-size mattress but you can always modify the dimensions to fit your mattress.

Can I build a platform bed without a headboard?

You absolutely can! We shared these platform bed plans separate from the headboard plans because it can stand alone without a headboard or, you can mix and match the platform bed plans with a different headboard design.

Is this bed sturdy enough without a box spring?

This bed is incredibly sturdy and no box spring needed! The cleats offer the support for the mattress slats. You can make the bed frame even more sturdy with short support blocks installed underneath the slats. This is highly recommended for mattresses larger than a full-size. Using the slats verse a box spring is a good option to save money and allows for a lower profile, more modern looking bed.

Would you still recommend this approach today?

Absolutely! We have been building furniture the same way for over 15 years. It’s sturdy and durable! The only changes I would make would be to rip the round edges with my table saw and change the stain colors!
