Today, we’re showing you the easiest way to build a platform bed with legs for under $50! This project is so easy and makes a huge impact.

We have been making over our guest bedroom, with furniture builds like midcentury side tables and a console table, and a color block wall.

The old dark wood 80’s bed just wasn’t going to cut it, so we built a platform bed in one day for less than the cost of Thai food takeout.

How much does it cost to build a platform bed?

We built this bed for $50 worth of wood.

It will cost you more if you don’t have stain, screws or a pocket hole jig on hand, but that won’t add much to the cost.

DIY Platform Bed

The main thing to consider with a platform bed is how high you want it to be from the ground.

We chose 9 inches because we have our rolling under-bed storage for wrapping paper underneath.

It was important that our platform bed have legs so that we could take advantage of that precious storage space!

When making your measurements for a platform bed, the inner dimensions of your bed frame need to be the same dimensions as your bed.

We built this for a double/full size bed, and the standard dimensions are 53″ x 74″.

How to build a platform bed frame

There are lots of ways to build a platform bed with all sorts of styles. This is a simple box bed with legs and slats.

We started by cutting and sanding all our wood to the dimensions needed (see the how-to card below for the full cut list).

Cuts needed for DIY platform bed
These pieces are laid out how they will attach. Basically fold them in and screw!

All the pieces in this build are attached using a Kreg Jig.

I usually use the Kreg K4, but since these are big, long 2x6s, it is a lot easier to clamp on the brand new Kreg 320 directly to the wood.

I absolutely love the 320. It is super user-friendly and great for beginner woodworkers.

The 320 has a thickness gauge which allows you to determine the exact thickness of your wood and then set everything on the 320 to that thickness.

You can set the jig itself and the stop collar on the drill bit to the same dimension to avoid any miscues.

This will also tell you what length screw to use. For the 2x4s and 2x6s used in this project, you need to use 2 1/2 inch Kreg screws.


Steps to Build a Platform Bed

First step was to build the outside box frame by connecting the four sides of the bed.

Next, we attached support railings along the insides of each side of the frame.

Since we were using 2x4s, we subtracted 7 inches from the long sides and 3 inches from the short sides to account for the other pieces.

Attaching supports of DIY platform bed

We added legs to the bottom of the 2×4 supports along the front and back.

We cut the same angled legs as we did on our DIY midcentury crib and IKEA Hemnes dresser hack.

The last step is to add the support for the mattress.

We attached two more 2x4s down the middle length of the bed and then laid 1×4 slats across the width.

Final Results

We popped the mattress into the frame and it fit perfectly.

We’re keeping the comforter and everything tucked down into the frame so that it stays prominent.

We love how this DIY platform bed turned out. It is sleek and modern and takes up much less space than the old bed.

Legs of DIY platform bed

I love how we built this for $50.

Our plan before was to build casings to go around the old headboard and foot board because I was worried about building an actual bed.

Turns out this was so much easier than building casings would have been.

This build might seem like a larger-scale build, but it was extremely simple. It’s a box with legs!

This is a great beginner woodworking project to really get you feeling like a pro.

It was all made so much easier thanks to the versatility of the Kreg 320 Jig.

We still need to build a headboard, but this plan for how to build a platform bed is super simple to follow!

What is the best wood to use for a platform bed?

You can use any species of wood to build this platform bed. We chose pine because it is the cheapest wood at the hardware store and we wanted to complete this project on a small budget.

Do I need a special mattress for a platform bed?

No, you can use any mattress on this bed. Just don’t use a boxspring! That is the beauty of a platform bed – the mattress sits directly on the wood.

How much does it cost to build a platform bed?

There are a few factors that will determine how much it costs to build your platform bed. The main one is type of lumber used. The second factor is what tools or supplies you have on hand or can borrow. We built this double sized bed for just under $50 worth of lumber – we had all of the tools on hand already.
