What Will You Need?

Gather all the necessary materials and tools before you start building your trundle bed. Here’s a list of items you’ll need:

  • Wood for the frame (you can choose from various types, such as pine or plywood)
  • Screws
  • Drill
  • Saw
  • Sandpaper
  • Measuring tape
  • Pencil
  • Paint or stain (optional)
  • Mattress for the top bed
  • Trundle mattress (can be a foam or air mattress)
  • Bedding (sheets, blankets, and pillows)

It’s always a good idea to have extra screws and wood in case of any mistakes or miscalculations. Additionally, make sure you have enough space to work on the project comfortably.

10 Easy Steps on How to Build a Trundle Bed

Step 1. Measure and Cut the Wood:

The Space Available Beneath It

Begin by determining the size of your main bed and the space available beneath it. Use these measurements to size your trundle bed accordingly. You’ll want to leave enough clearance for bedding and for easy pullout. Then, measure and cut the wood for the trundle bed frame, ensuring each piece is accurately sized for a snug fit.

Step 2. Assemble the Frame:

With your wood cut to the correct dimensions, lay out the pieces to form the base frame of the trundle bed. Start by attaching the longer side pieces to the shorter end pieces. Use screws and the drill to secure the frame together, forming a rectangular shape. Make sure the corners are at right angles for a uniform structure.

Once the base is assembled, reinforce the frame with additional screws at each corner for added stability. Remember to predrill holes to prevent the wood from splitting.

Step 3. Attach the Bottom Panel:

Now that your frame is assembled, it’s time to attach the bottom panel supporting the trundle mattress. Cut a piece of plywood or wood you choose to fit snugly within the frame. Place the panel on the frame and check for a proper fit.

Once you’re satisfied, secure the panel by drilling screws through the frame and into the panel around the perimeter, spacing them roughly 6 inches apart. Sands the edges of the bottom panel before installing it to remove any splinters or rough areas that could damage the mattress.

Step 4. Install the Supports:

In addition to the bottom panel, you’ll need to install center supports to ensure even weight distribution and to prevent sagging. Measure and cut additional pieces of wood to act as center supports running perpendicular to the longer sides of the frame.

Space these supports equally along the length of the bed. Attach the supports securely to the bottom panel and the sides of the frame using screws. These must be attached firmly as they will carry the bulk of the load.

Step 5. Add the Wheels or Casters:

Attach wheels or casters to the bottom corners of the frame to make the trundle bed easy to pull out and push in. Select appropriate wheels for your flooring to prevent scratches and ensure smooth movement.

Attach Wheels or Casters to the Bottom Corners

Turn the frame over and position the casters at each corner, marking the screw holes with a pencil—drill pilot holes to prevent splitting the wood, and then screw the casters into place securely. If your trundle bed will be on a hardwood floor, consider using rubber wheels to minimize noise and scratches.

Step 6. Sand the Frame:

Once you have the wheels or casters attached, turn the trundle bed frame right side up and begin sanding all surfaces. This includes the frame and the supports that have been installed. It’s crucial to smooth every surface to prepare for painting or staining and remove any potential splinters.

Start with a coarse sandpaper to remove rough patches, and then work your way down to a finer grit to achieve a smooth finish. Pay special attention to corners and edges where hands will most likely touch the bed when pulling it in and out.

Step 7. Prime and Paint or Stain:

After the frame is smoothly sanded, it’s time to apply a primer and paint or stain to your trundle bed. This not only adds a layer of protection but also gives you the opportunity to customize the look of your bed to match your room’s decor. When choosing a paint or stain, consider one with a durable finish since the bed will be moved frequently.

Apply the primer first, wait for it to dry, and then apply your chosen paint or stain with smooth, even strokes. Allow ample time for the paint or stain to dry completely before proceeding to the next step.

Step 8. Attach the Bedding Support Slats:

Now it’s time to prepare the base for the mattress. Measure the interior length of the frame and cut a series of wooden slats that will fit across the width of the trundle bed. These slats provide additional support for the mattress and ensure it doesn’t sag or fall through.

Prepare the Base for the Mattress

Position the slats evenly across the frame, spacing them about 2 to 3 inches apart. Secure each slat to the frame with screws, drilling them in place carefully to avoid splitting the wood. This step is essential for creating a supportive and comfortable sleeping surface.

Step 9. Add Finishing Touches:

Your trundle bed is nearly complete, but a few finishing touches can greatly affect its functionality and appearance. If there are any screw heads visible, you can cover them with wood filler for a clean look. After the filler dries, sand it down until it’s flush with the wood’s surface. If you painted your bed, touch up these spots with the paint.

Additionally, installing a fabric liner on the bottom panel can help protect the mattress from any splinters or rough spots that might have been missed during sanding. For ease of use, you may also want to add handles or knobs on the sides of the trundle to make it easier to pull out from under the bed.

Step 10. Test the Trundle Bed:

Before bedding is placed and the trundle bed is put into active use, it’s necessary to perform a series of tests to ensure safety and functionality. Gently pull the bed out and push it back in to verify the wheels or casters roll smoothly without resistance. Also, check that there is easy clearance under the main bed without any obstructions.

Test the stability and strength of the frame and slats by applying weight to various areas. If any weaknesses are detected, it may require additional reinforcement. Once these tests are satisfactory, you can declare your DIY trundle bed project a success and proceed to dress it with a mattress and bedding.

By following these steps, you can create a functional and stylish trundle bed that will be perfect for accommodating overnight guests or providing extra sleeping space in a shared bedroom.

5 Additional Tips and Tricks

  1. Maximize Stability: Reinforce the structure with corner braces or additional support beams to ensure the trundle bed can safely support the weight of a mattress and a sleeper.
  2. Choose the Right Casters: Select high-quality casters that can lock into place to prevent the trundle from rolling out unintentionally, and make sure they are suitable for your floor type to prevent damage.
  3. Consider Mattress Thickness: Remember to account for the mattress thickness when building your trundle bed frame to ensure it will fit neatly under the main bed when not in use.
  4. Smooth Edges: Sand all edges and corners thoroughly to prevent snags and scratches on bedding or injury to hands while handling the trundle.
  5. Add a Pull-Out Handle: Install a discrete pull-out handle on the trundle bed. This will make it easier to access and add a professional finish to your DIY project.

When building your trundle bed, remember to follow these tips to enhance function, safety, and aesthetics.

5 Things You Should Avoid

  1. Ignoring Weight Limits: Remember to consider the importance of weight limits for your trundle bed. Avoid choosing materials that are too flimsy to support the weight of the mattress and sleeper, as it could lead to structural failure.
  2. Skipping a Bed Plan: Refrain from starting your project without a comprehensive plan. Avoid the temptation to “wing it” – proper measurements and a straightforward design are crucial for a successful build.
  3. Using Low-Quality Wood: Avoid using low-quality or untreated wood, which may be prone to warping, cracking, or succumbing to pests over time. Invest in higher-quality materials for a longer-lasting bed.
  4. Forgetting Ventilation: Don’t overlook the need for proper mattress ventilation. Avoid designing a trundle without any space for air circulation, which could lead to moisture buildup and mold.
  5. Neglecting the Main Bed: Focus on something other than the trundle bed at the expense of the leading bed’s functionality and aesthetics. Ensure that your design complements and does not impede the use and look of the main bed.
  6. Leaving Sharp Edges: Remember to sand down sharp edges and corners on the trundle bed, as they could pose a safety hazard for both sleepers and bedding. Always prioritize safety in your DIY project.

By following these tips, you can avoid common mistakes and ensure that your trundle bed is not only functional but also durable and safe.

5 Different Ways to Customize Your Trundle Bed

  1. Paint or Stain: One easy way to personalize your trundle bed is by painting or staining it in a color that suits your style and room decor. You can even add patterns or designs for a unique touch.
  2. Add Decorative Trim: Jazz up your trundle bed by adding decorative trim, such as a border or scrollwork, to the frame. This can give it a more sophisticated and elegant look.
  3. Install Drawers: If you have enough space, consider adding drawers to your trundle bed for extra storage. You can use them to store bedding, clothes, or other items, making your trundle bed even more practical.
  4. Create a Headboard: Build a headboard for your trundle bed to make it look more like a traditional bed and add visual interest to the room. Depending on your preference, you can use different materials, such as wood, fabric, or metal.
  5. Add Wheels: Instead of using casters, add wheels to your trundle bed for more effortless mobility. This is especially useful if you need to move the bed frequently.

With these customization options, your trundle bed can become a unique and personalized piece of furniture in your home. Get creative and have fun with your DIY project!

Ultimately, the best type of wood for your trundle bed depends on your preferences and budget. Just make sure to choose a high-quality, sturdy wood to provide a solid foundation for your trundle bed.  So go ahead and start building your dream trundle bed with confidence!

Which Color is Ideal for a Trundle Bed?

  1. Neutral Tones: If you want a timeless and versatile look, consider painting or staining your trundle bed in neutral tones like white, beige, or gray. These colors can easily match any room decor and be easily updated with new bedding.
  2. Bold Colors: For a more daring and unique look, opt for bolder colors like navy blue, deep red, or emerald green. These colors can add a pop of color to the room and make your trundle bed stand out.
  3. Natural Wood Tone: If you want to highlight the natural beauty of the wood, consider leaving it unfinished or using a clear sealant. This option is perfect for those who prefer a more rustic or organic look.
