The Ultimate Guide to Building a High Rise Bed: DIY Plans & Safety Tips

Daniel Jun 01, 2026

Building a high rise bed transforms a child’s room or a small studio into a space of endless possibility. Instead of sacrificing floor space, you reclaim it, creating room for a play area, a reading nook, or a dedicated study zone beneath the elevated sleeping quarters. This project requires careful planning, precise measurements, and a commitment to safety, but the result is a custom piece of furniture that grows with your family and adds a unique character to any room.

Planning Your High Rise Bed Design

The first step is not shopping for lumber, but assessing your specific needs and constraints. Measure the room dimensions, doorways, and staircases to ensure the finished bed can be maneuvered into place. Decide on the final height, keeping in mind that the underside of the mattress should ideally sit at least 30 inches from the floor for an adult to feel comfortable sitting up in bed. For children, a lower height of 24 to 30 inches is often safer and easier to navigate. Sketch a detailed plan, noting the placement of the ladder, guardrails, and access points to ensure the layout flows naturally within the space.

Choosing the Right Materials

Selecting the right materials is critical for both structural integrity and aesthetics. Most builders opt for solid wood like pine, maple, or oak for its strength and warmth, though engineered wood like plywood can be used for the bed deck if reinforced properly. The hardware is equally important; use heavy-duty lag bolts and steel brackets rather than simple wood screws to ensure the frame remains secure over time. For the ladder, consider a sturdy plywood side ladder or a series of steps spaced no more than 10 inches apart to prevent a child’s foot from slipping through.

Constructing the Frame and Foundation

Begin by building the ground-level base frame, which will serve as the anchor for the entire structure. This frame should be assembled on a perfectly level surface to prevent future sagging or stress on the joints. Once the base is square and solid, construct the upper frame that will sit directly above it. Use identical bracing techniques for both levels to ensure they share the load evenly. It is vital to attach the two frames securely using vertical support posts and heavy-duty connectors, creating a single, rigid unit that feels like a single piece of furniture rather than two separate boxes.

Installing Safety Guardrails

Guardrails are non-negotiable for any high rise bed, and they must be installed before the mattress is ever placed on the bed. The top of the rail should be at least 5 inches above the mattress surface when it is at its highest position. The gaps between the rails and between the rail and the wall should be no wider than 4.5 inches to prevent a child’s head from getting trapped. Ensure the rail extends at least 18 inches beyond the sides of the mattress to stop a restless sleeper from rolling out, and double-check that all rail connections are bolted tight with no wobble.

Finishing Touches and Final Checks

With the structure complete, turn your attention to the details that define the character of the bed. Edge banding can be applied to plywood surfaces to create a clean, seamless look, and a coat of non-toxic paint or stain will protect the wood and bring the design to life. Install the ladder at a comfortable angle, ideally between 60 and 70 degrees, and secure it with both bolts into the side rails and steps into the vertical supports. Before allowing anyone to sleep in the bed, conduct a final safety audit by applying weight to the structure and testing the stability of the rails.

Optimizing the Space Below

The area beneath a high rise bed is perhaps its greatest asset, and the final step is to maximize its functionality. Position a sturdy desk beneath the canopy for a homework station, or fit it with soft cushions to create a cozy daybed for reading and gaming. Ensure there is adequate headroom for anyone sitting up in bed, and avoid storing heavy items directly above the sleeping area to mitigate risk. By treating the lower zone as a purposeful room within the room, you transform the entire piece from a simple bed into a multi-functional sanctuary.
