Sturdy DIY Bunk Bed Made from 2x4s and 2x6s

This project was built and designed by Jay Bates. It’s a durable and straightforward bunk bed that balances cost, strength, and accessibility using standard construction lumber.

Jay’s approach combines smart joinery and thoughtful layout to create a bunk bed that looks clean, feels solid, and can be made with basic tools. The result is a strong, no-frills design that works well for kids’ rooms, guest spaces, or shared living setups.

Starting with the Bed Frames

The bunk bed is built around two bed frames, each made from 2×6 boards. This lumber choice adds rigidity and minimizes flex, even under daily use.

To keep the wood looking natural, minimal sanding is done—just enough to remove factory markings. Jay runs each board through a thickness planer to expose clean grain and level the surface without removing too much character.

Making the Mattress Supports

Mattress slats rest on 2×2 ledgers mounted along the inner edges of the frame. Rather than buying 2x2s, Jay rips down 2x4s to size, making better use of materials and saving on cost.

The slats themselves are also cut from 2x4s, which are often cheaper than traditional 1x4s. A rabbet is cut along each edge of the frame to seat the slats. Instead of screwing every slat in place, only the center one is fixed—while the rest are dropped in using spacers made from the rabbet offcuts.

Circular Saw Tips and Jig Use

Jay shows that even without a table saw, accurate cuts are still achievable. By making a simple jig, he’s able to guide a handheld circular saw for precise rabbets.

This jig setup is especially useful for DIYers with limited tools. It proves that you can build professional-quality furniture without needing a full workshop setup.

Constructing the Legs

The legs are built as L-shaped assemblies using a 2×4 joined to a 2×6 with pocket hole screws. This method increases strength while hiding all visible fasteners for a cleaner look.

Pocket holes are positioned so they won’t be seen once the bed is assembled. This creates a professional appearance without the need for additional trim or plugs.

Assembling the Bed

Small locator blocks are used during assembly to line everything up consistently. Once each frame is set into place, it’s secured using wood screws that hold tight and prevent shifting or racking.

The design results in a bunk bed with no visible screws or bolts on the outside. This creates a seamless finish that looks clean from any angle.

Built-in Ladder Access

One standout feature is that either end of the bunk bed acts as a full-size ladder. The vertical spacing between boards is ideal for climbing, eliminating the need for a separate ladder piece.

This design makes access easier and helps conserve floor space—especially important in tighter bedrooms or shared spaces.

Plans for Finishing

At the time of filming, Jay hasn’t yet applied a finish to the bunk bed. He mentions plans to experiment with steel wool and vinegar for a weathered effect, followed by a layer of briwax.

That finishing process will be shared in a future video. For now, the raw wood look adds to the simplicity and flexibility of the design.

Affordable, Functional, and Repeatable

What makes this project especially useful is how replicable it is. The materials are common, the tools are accessible, and the build techniques are within reach for most intermediate woodworkers.

The design can be adapted to fit different mattress sizes or room dimensions. It’s also sturdy enough to be used in real-world settings without modification.
