Materials needed for building a DIY platform bed twin

Building a DIY platform bed twin can be an exciting project. However, it requires careful planning, proper tools, and materials to achieve the desired outcome. In this article, we will discuss the materials needed for building a DIY platform bed twin.


Wood is the most crucial material needed for building a DIY platform bed twin. You can use any type of wood, but the most popular options include pine, plywood, and MDF. Pine is an affordable option, but it may not be as strong as other types of wood. Plywood is stronger, but it may have voids that can affect the quality of the bed. MDF is a popular option because it is strong, affordable, and smooth. Whatever wood you decide to use, make sure it is untreated and smooth to prevent splinters.

Screws, Nails, or Bolts

You will need screws, nails, or bolts to hold the bed frame together. Screws are a popular option because they are strong and easy to use. However, nails and bolts can also be used depending on personal preference. When selecting screws, nails, or bolts, make sure they are long enough to go through the wood and hold the bed together securely.

Drill and Drill Bits

A drill is an essential tool needed for building a DIY platform bed twin. It is used to make holes on the wood, where the screws, nails, or bolts will be placed. A drill bit is used to create the hole, and it is important to use the right size of drill bit to prevent splitting the wood.


A saw is necessary for cutting the wood to the required size. A circular saw or a jigsaw can be used for the job. The circular saw is the best option for making straight cuts, while the jigsaw is ideal for making curved cuts.

Tape Measure and Pencil

A tape measure and a pencil are also required for building a DIY platform bed twin. The tape measure is used to measure the length and width of the bed frame, while the pencil is used to mark the position where the saw will make the cut.

Sanding Paper or Electric Sander

Sanding the wood is important to make it smooth and prevent any splinters. Sandpaper or an electric sander can be used for the job. Start with a coarse sandpaper to remove any rough spots, and then finish with a fine sandpaper to make the wood smooth.

Paint or Stain and Brush

You can choose to paint or stain your DIY platform bed twin. Paint is ideal if you want a colorful bed that matches your room decor, while stain is perfect if you want to highlight the wood’s natural beauty. You will also need a brush to apply the paint or stain onto the wood.

In conclusion, building a DIY platform bed twin requires the right materials and tools. When selecting the materials, make sure they are strong, untreated, and smooth. Also, use the right tools, such as a drill, saw, tape measure, and pencil. With these materials and tools, you can create a beautiful and sturdy platform bed that will last for years.

Measurements and cutting of the bed frame pieces

When starting the DIY project of building a platform bed twin, it is essential to take precise measurements to ensure that all the bed frame pieces fit together correctly. One of the most crucial elements to get right when building a platform bed is the height of the bed frame. Typically, a bed frame needs to be around 16-18 inches high to accommodate the height of a comfortable mattress and box spring.

Another vital part of measuring for a platform bed twin is the length and width of the bed frame itself. For a twin-size mattress, the length needs to measure 75 inches while the width should be 39 inches.

Once all the necessary measurements have been taken, the next step in building a platform bed twin is cutting the bed frame pieces into the right shape and size. To do this, you’ll need a saw and be comfortable using it. It’s also a good idea to wear safety goggles to protect your eyes from any flying debris while cutting.

The first piece that needs cutting is the bed frame’s top. Cut two pieces to the desired width and length, being sure to account for the height you want. The bed frame’s bottom will also need to be cut into two pieces of equal size, so the twin bed is balanced, and both sides sit level. These bottom pieces should also be cut to fit the height of the bed frame.

The bed frame’s sides need to be cut to the right length and height, with the height matching the height of the bottom bed frame. When using a saw, ensure that the cuts remain straight and measure precisely to prevent uneven edges and wobbling later on.

When cutting the bed frame’s headboard and footboard, the height should match the bed frame’s sides’ height. The length should be the same length as the bed frame’s top. It’s essential to measure the headboard and footboard pieces correctly, as an error in size here can lead to an unstable bed.

Once all the pieces have been cut, it’s crucial to double-check the sizes and make sure everything fits together correctly. You should also use a sander to remove any rough edges or splinters before painting or staining the bed frame.

Overall, with the right tools and a careful approach, it’s relatively easy to measure and cut the bed frame pieces needed to build a platform bed twin. By being precise with measurements and making sure all the pieces fit together correctly, you’ll build a sturdy, reliable bedframe that will serve you for years to come.

Step-by-step instructions for constructing the platform bed

If you’re looking for a budget-friendly, stylish and easy-to-build bed in your space, then a platform bed could be the perfect option. With its clean lines and minimalist design, the platform bed has gained immense popularity over the years. The best part? You don’t need a lot of woodworking experience or fancy tools to build a platform bed twin. In this article, we’ll guide you through the step-by-step process of constructing a platform bed twin.

Materials and Tools Needed

Before we move onto constructing the bed, let’s start by gathering the materials and tools we’ll need for the project. Here’s a list of everything you’ll require:

  • Materials:
  • 1×4 lumber – 8ft boards (6 pieces)
  • 2×4 lumber – 8ft boards (3 pieces)
  • 1/2-inch plywood – 4ft x 8ft (1 piece)
  • Wood screws (1 ¼ inch)
  • Wood glue
  • Sanding paper (100 grit)
  • Wood finish of your choice (optional)
  • Tools:
  • Measuring tape
  • Saw (circular saw or miter saw)
  • Drill
  • Screwdriver bit
  • Cordless drill
  • Countersink drill bit
  • Sander (orbital or belt sander)
  • Paintbrush (if applying a wood finish)

Step 1: Build the frame

The first step is to build the frame of the platform bed. Take two 1×4 boards and attach them to the 2×4 board using wood screws. Repeat this with two more 1×4 boards to create the second side of the frame. Now connect the two sides using the remaining 1×4 boards. Be sure to predrill the holes and countersink the screws. This will ensure a clean finish and prevent the wood from splitting.

Step 2: Add support to the frame

The next step is to reinforce the frame by adding support beams. Take two 2×4 boards and cut them to the length of the frame. Attach them perpendicular to the frame at each end using wood screws. This will distribute the weight of the mattress evenly and prevent any sagging over time.

Step 3: Install the plywood platform

It’s now time to install the plywood platform. Place the 1/2-inch plywood on top of the frame, taking care to align the edges of the plywood with the edges of the frame. Attach the plywood to the frame using wood screws, placed every six inches around the perimeter. Be sure to counterbore the screws and fill the holes with wood filler to create a flush finish.

Once the plywood is securely attached to the frame, it’s time to sand the platform. Use sandpaper to smooth out any rough edges or imperfections. This will help to ensure the finish looks smooth and professional. If desired, you can apply a wood finish of your choice to the platform (such as paint, stain or varnish) for added durability and style.

Step 4: Assemble the bed

The final step is to assemble the bed. To do this, simply place the mattress on the plywood platform and you’re done! Congratulations – you’ve built your very own platform bed twin.

In conclusion, constructing a platform bed twin is a great way to add a modern touch to your bedroom without breaking the bank. With just a few simple materials and tools, you can build a stylish and functional bed that’s sure to impress. By following these step-by-step instructions, you’ll have your platform bed twin up and ready to use in no time at all.

Finishing Touches: Sanding, Staining, and Decorating the Bed Frame

The last step to have your DIY platform bed twin completed is to add the finishing touches. This is where you can get creative and make the bed frame look exactly how you want it to. In this step, we will talk about sanding, staining, and decorating the bed frame. These three elements will give your bed frame the perfect finish.


The first step is sanding. Sanding is an essential process to smooth out any rough edges or uneven surfaces that can ruin the overall appearance of the bed frame. Once your bed frame is assembled, take time to inspect the frame for any sharp edges, splinters, or any rough spots that need to be sanded. You can use a fine-grit sandpaper for this, as they work best for finishing work. If you have an electric sander, you can use it, but be careful not to overdo it. You don’t want to remove too much wood, and it’s better to be safe by doing it manually.

After sanding, make sure to wipe the bed frame down with a tack cloth or a damp cloth to remove any dust. This step ensures that your stain will adhere uniformly to the wood, eliminating any splotches or blotches on the surface.


Staining is an excellent way to enhance the natural wood grain and add visual appeal to your bed frame. Choosing the right color of stain is crucial; it has to complement your bedroom color scheme. You can choose from oil-based stains and water-based stains; each has different characteristics. Oil-based stains are more durable, but they require more time to dry, while water-based stains dry up faster but might not be as durable.

When applying the stain, use a brush or a rag and apply the stain in the direction of the wood’s grain. Once you’ve completed the first coat, let it dry for a few hours before applying a second coat, if necessary. Be patient while the stain dries don’t rush it. After applying the final coat, let it dry overnight before moving onto the next step.


The last step is decorating the bed frame. You can add finish touches to the bed frame by using paint or any other decoration of your choice. You can add decorative moldings to the headboard of the bed, or you can add upholstered panels if you want a stylish look. If you prefer a minimalist look, you can keep the bed frame as is or add a touch of elegance by adding a canopy to the bed.

Another way to decorate is by adding accessories to your bed linen. Use decorative pillows, throws, or a duvet cover to spruce your bed. The possibilities are endless, and the key is to find the right accessories that fit your style.

In conclusion, adding the finishing touches to your DIY platform bed twin is a fun and exciting part of the bed frame making process. Sanding, staining, and decorating are easy and simple steps that will give your bed frame a polished look. Once you have completed the final step, you can be proud to have created a bed frame that is stylish, functional, and tailored to your liking.

Tips for Selecting the Right Mattress to Pair with Your DIY Platform Bed Twin

Once you have built your DIY platform bed twin, the next step is to find the right mattress to pair with it. Here are some tips to help you select the perfect mattress:

1. Consider the Size of Your Bed Frame

The size of your bed frame will determine the size of mattress you need. Make sure you measure your bed frame carefully before buying a mattress. Twin-sized mattresses are the perfect fit for a DIY platform bed twin.

2. Determine the Type of Mattress You Want

There are many types of mattresses available in the market. Some popular options include memory foam, innerspring, latex and hybrid mattresses. Each of these mattresses has its pros and cons, so it is important to do your research and select the one that suits your sleeping style and budget.

3. Think About Your Sleeping Position

Your sleeping position is an important consideration when choosing a mattress. If you sleep on your stomach, you will need a firmer mattress to support your body. On the other hand, if you sleep on your side, a softer mattress will be better. If you are a combination sleeper, look for a mattress with medium firmness that can accommodate different positions.

4. Consider Your Body Weight

Your body weight can affect the choice of mattress, especially when it comes to providing the right level of support. If you are on the heavier side, you may need a firmer mattress to prevent sagging. If you are lighter, a softer mattress may be more comfortable for you.

5. Check for Mattress Quality

When buying a mattress, look for quality materials that can ensure durability and comfort. Check for the density of the foam and the coil count of the innerspring. A good quality mattress will provide better support and last longer. You may have to pay a higher price for a good quality mattress, but it is worth the investment in the long run.

With these tips in mind, you can find the perfect mattress to go with your DIY platform bed twin. Sleep well!
