Frame Construction
Start by building the frame using 2x6s and 2x4s. Secure these boards to the wall studs using lag bolts for stability. Measure carefully and ensure the frame is square to the wall. Use a level to keep everything aligned.
For the bed's base, evenly space 2×4 slats across the frame. Add extra support where the ladder will attach. Choose plywood for the mattress base and secure it firmly to the slats with screws.
Construct a headboard using tongue and groove boards, attaching it to the frame for added support and aesthetics.
Finally, build a ladder using 2x4s. Make it strong enough for regular use but light enough to move if needed. Position the rungs symmetrically for easy climbing.

Building and Installing Ladder
When crafting the ladder, consider both safety and functionality. Use 2x4s for the side rails and rungs. Choose an angle that balances space-saving with ease of use – not too steep, but not too shallow.
Space the rungs evenly, typically 10-12 inches apart. Mark each spot carefully before attaching. Secure rungs with screws through the side rails, ensuring they're straight and sturdy.
Pay attention to the ladder's placement. The bottom should rest on a non-slip surface, while the top secures against the loft frame. Consider using brackets or hooks for added stability.
Test the ladder by climbing it yourself to ensure it's secure and steady. Make sure it blends well with the overall design of the loft bed.

Platform and Joist Installation
Install joists to support the platform, using 2x4s and joist hangers. Space them about 12 inches apart for optimal support. Attach them securely to the frame on both sides.
Carefully place the plywood platform onto the joists, ensuring it's squared up. Use a level to check alignment. Screw the plywood down along each joist, aiming for a firm, wiggle-free surface.
Test the platform for creaks or dips as you work. A solid platform ensures comfort and prevents disturbances during sleep.

Finishing Touches and Safety Features
Sand down any rough edges before painting to prevent splinters and create a smooth finish. Choose a paint color that complements the room's decor. Apply primer, then paint in even layers, allowing each to dry thoroughly.
Install guardrails around the perimeter of the bed, leaving space for the ladder. Use sturdy screws and ensure the rails are securely attached. Aim for a height of at least five inches above the mattress surface for safety.
Consider adding non-slip decals to the ladder rungs for extra grip, especially useful for sock-wearing climbers.
Step back and inspect your work. The finished loft bed should be both visually appealing and structurally sound, ready for years of use.

Your completed loft bed is a blend of craftsmanship and functionality, offering a safe and stylish sleeping space for years to come.
