Murphy beds are a game-changer in camper van conversions, especially when space is tight. In this guide, we’ll show you exactly how to build a Murphy bed system in a medium roof Ford Transit using 8020 aluminum framing and a simple spring-loaded hinge design. This is the same method used in Thomas’s build at Odyssey Custom Vans—proven, space-efficient, and clean-looking.
Why a Murphy Bed Works for Van Life
Murphy beds, or fold-down beds, allow you to reclaim your living space during the day. Unlike fixed platform beds, a Murphy bed folds up and stores vertically against the wall, creating more usable space for lounging, cooking, or working.
Materials Used
- 8020 Aluminum Framing (1.5” square profile)
- Spring-loaded fire door hinges (3.5″, reliable brand from Lowe’s)
- IKEA bed slats with webbing
- Titan Vans 20-gallon water tank (for under-bed support and storage)
- Stainless steel screws and lock washers
- Ratchet straps and clamps (for hinge alignment)
- Tools: Drill, tap set, vacuum, miter saw
Step 1: Plan Your Layout
The success of your Murphy bed depends on precise layout planning. In our build, the water tank was on the left and the power system on the right—but these can be swapped.
The two critical measurements:
Vertical clearance: Interior height of your van minus the ceiling thickness and height of any under-bed systems (like tanks or drawers).
Horizontal clearance: The width available for the Murphy bed frame when folded up and when fully deployed.
Pro Tip: Leave a ¼” gap at both the top and bottom of the bed system to allow smooth opening and closing.
Step 2: Frame Construction with 8020 Aluminum
Build your Murphy bed frame using 8020 aluminum extrusion:
- Use four angle brackets for the corners.
- Add a center support rail for slats.
- Drill and tap all main joints—especially the center support—to prevent twisting under the pressure of bent bed slats.
Tip: Pre-drill holes in 8020 for cleaner results and fewer stripped screws.
Step 3: Mounting the Frame and Hinges
This is the most complex part of the build due to hinge geometry.
- Use spring-loaded fire door hinges for lift assist.
- Attach hinges to the top of the bed frame first.
- Keep the bottom support bar loose initially for micro-adjustments.
- Use a ratchet strap to temporarily suspend the bed for easy hinge alignment.
Hinge Geometry Tip: Your hinge won’t rotate in a perfect arc due to its position on the outside of the frame. Allow adjustment room in your build to compensate for this variation.
Step 4: Add Bed Slats
Use IKEA bed slats (48″ width in our case) for mattress support:
- Cut the slats to size, allowing a center overlap for support.
- Pre-drill and attach with lath screws to prevent the aluminum from warping.
- Leave a small gap between slats using one as a spacer for even layout.
Bonus: The curved design of the slats adds flex and comfort.
Step 5: Fine-Tuning and Adjustments
Once your Murphy bed is mounted:
- Check that the bed lands level on its support when folded down.
- Adjust the bottom bar height if the frame sits too high or low.
- Preload the spring hinges using the included hex wrench and locking pin for lift assist.
Optional: Add 80/20 locking latches and felt pads for quiet operation and a snug fit.
Final Result: Clean, Functional, Zen-Like
The result is a smooth-operating Murphy bed that folds up into a clean aluminum frame recess. With exposed slats and clean lines, the final product adds both style and utility to the van’s living area.
This exact build was featured at Adventure Van Expo in Chattanooga, TN, showcasing what’s possible with a thoughtful, well-executed Murphy bed design.

FAQs
Q: What kind of mattress can you use?
A: A tri-fold or six-inch memory foam mattress works great. When folded in half, it fits into a 12″ wide frame cavity.
Q: Is this suitable for low-roof vans?
A: Not easily. Medium and high-roof vans work best due to required vertical clearance.
Q: Can you customize the face of the Murphy bed?
A: Absolutely. Wood, bamboo, or fabric paneling can be added if you prefer a different aesthetic.
