DIY Trundle Bed Frame: Maximize Space with a Customizable Pull-Out Bed

In today’s world, where space is often at a premium, finding creative solutions to maximize sleeping areas is essential. A DIY trundle bed frame is an excellent way to add extra sleeping space without compromising on style or functionality.

In this blog post, we’ll explore the benefits of a trundle bed frame and provide step-by-step instructions for building your own customizable pull-out bed.

Why Choose a DIY Trundle Bed Frame?

  1. Space-saving: A trundle bed frame allows you to have an extra bed without taking up valuable floor space when not in use.
  2. Versatility: Trundle beds are perfect for multi-purpose rooms, such as home offices that double as guest rooms or kids’ rooms that need extra sleeping space for sleepovers.
  3. Customization: Building your own trundle bed frame enables you to tailor the design to your specific needs and preferences, such as size, style, and storage options.
  4. Cost-effective: Creating a DIY trundle bed frame can be more affordable than purchasing a store-bought version, especially if you use repurposed materials or build it to fit your existing bed frame.

DIY Pull Out Bed Frame

Materials Needed

To build your own pull out bed frame, you’ll need the following materials:

Step 1: Measure and Plan

Before you start building your pull out bed frame, you need to determine the size of the mattress you’ll be using and measure the space where you plan to place the trundle bed. This will help you create a detailed plan and ensure that your DIY pull out bed frame fits perfectly in the designated area.

  1. Measure the length and width of your mattress, adding a few inches on each side to account for the frame.
  2. Measure the space under your existing bed frame or the area where you plan to place the trundle bed, ensuring there’s enough clearance for the pull out bed frame to easily slide in and out.
  3. Sketch out your design, including the dimensions of the frame, the placement of the caster wheels, and any additional features you want to incorporate, such as storage drawers or a headboard.

Step 2: Build the Frame

With your measurements and design plan in hand, it’s time to start building the frame for your pull out bed.

  1. Cut the 2x4s to the appropriate lengths for the main frame, based on your measurements. You’ll need two long sides and two short sides.
  2. Assemble the main frame by attaching the short sides to the long sides using wood screws and bolts. Make sure the frame is square and level.
  3. Cut the 1x4s to size for the slats that will support the plywood platform. The number of slats you need will depend on the size of your frame and the desired level of support.
  4. Attach the slats to the inside of the main frame, spacing them evenly apart. Use wood screws to secure the slats in place.
  5. Sand the entire frame to ensure a smooth surface and remove any rough edges.

Step 3: Create the Platform

The platform is the surface on which your mattress will rest. To create the platform for your pull out bed frame, follow these steps:

  1. Measure the inside dimensions of your frame and cut a piece of plywood to fit snugly within the frame.
  2. Place the plywood on top of the slats and secure it in place using wood screws. Make sure the plywood is level and firmly attached to the slats.
  3. Sand the edges of the plywood to ensure a smooth surface and remove any splinters.

Step 4: Attach the Caster Wheels

Caster wheels are essential for making your pull out bed frame easy to move and store when not in use. To attach the caster wheels, follow these steps:

  1. Flip your pull out bed frame upside down and mark the locations where you want to attach the caster wheels, typically one in each corner and one or two in the middle of the long sides, depending on the size of your frame.
  2. Drill pilot holes at the marked locations, being careful not to drill through the entire frame.
  3. Attach the caster wheels to the frame using the provided hardware, ensuring they are securely fastened.
  4. Flip the frame back over and test the caster wheels to make sure they roll smoothly and easily.

Step 5: Attach to the Main Bed (Optional)

If you’re building the pull out bed frame to fit under an existing bed, you may want to attach it to the main bed frame for added stability. To do this, you can use brackets or bolts to secure the pull out bed frame to the main bed frame.

  1. Measure and mark the locations where you want to attach the brackets or bolts on both the pull out bed frame and the main bed frame.
  2. Drill pilot holes at the marked locations, being careful not to drill through the entire frame.
  3. Attach the brackets or bolts to both frames, ensuring they are securely fastened and aligned.
  4. Test the pull out bed frame to make sure it slides in and out smoothly and remains stable when attached to the main bed frame.

Step 6: Sand and Finish

To give your DIY pull out bed frame a polished look and protect the wood from wear and tear, sand and finish the frame.

  1. Sand the entire frame, including the platform, using progressively finer grits of sandpaper until the surface is smooth and even.
  2. If desired, apply a wood stain or paint to the frame to match your room’s decor or add a personal touch. Be sure to follow the manufacturer’s instructions for application and drying times.
  3. Apply a clear protective finish, such as polyurethane, to seal the wood and protect it from moisture and scratches. Follow the manufacturer’s instructions for application and drying times.

Once your DIY pull out bed frame is complete, pair it with a high-quality Puffy Lux Mattress. They are designed to provide optimal support and comfort, ensuring a good night’s sleep for your guests or family members.

Trundle Bed Frame Design Ideas

Living in a small apartment, we needed to make the most of every square foot. Our home office doubled as a guest room, and we often found ourselves struggling to accommodate overnight guests comfortably. That’s when we decided to build a DIY trundle bed frame.

We designed a trundle bed frame that would fit seamlessly under our existing daybed, creating a comfortable sleeping space for guests when needed. The project took a weekend to complete, and we were thrilled with the result.

The combination of the space-saving trundle frame and the comfort of the Puffy Lux Mattress has been a game-changer for our multi-purpose room. Now, we can easily transform the space from a home office to a cozy guest room in minutes, without sacrificing comfort or style.
