Build a bed frame with storage by constructing a platform base with integrated drawers or open cubbies beneath the mattress support.
For the full breakdown, see our best King Bed Frame with Storage guide.
Building your own bed frame with storage is one of the most practical woodworking projects you can take on—you get a custom size, exactly the storage layout you want, and you skip the $800+ price tag of retail versions. The core concept is simple: a rigid perimeter frame, a center support beam, a slat system for the mattress, and drawers or cubbies built into the space below. Most published plans follow this same sequence, and understanding it before you buy materials will save you money and frustration.
The Core Structure: Perimeter Frame, Center Support, and Slats
Every bed frame with storage starts with the same skeleton. You build a rectangular perimeter frame from plywood or dimensional lumber—this is the structural heart of the bed. Then you add a center support beam that runs the length of the bed and sits on legs or a low-profile stringer system. This beam is not optional; it prevents the mattress support from sagging and gives your drawers a stable surface to slide against.
On top of the frame and center beam, you install slats perpendicular to the length of the bed. These support the mattress and distribute weight evenly. The IKEA BRIMNES assembly documentation (document code AA-473492-22) shows this exact layout: a frame, support beams, and slats, with the storage built into the space beneath. For a DIY version, 1×4 or 1×6 boards spaced 3–4 inches apart work well, and you can either screw them down or rest them in routed notches on the frame rails.
The height of the frame matters more than you might think. Aim for a finished height that allows comfortable sitting on the edge—typically 16 to 20 inches from the floor to the top of the slats. This gives you enough vertical space inside for drawers or bins that actually hold things.
Building Drawer Boxes, Cubbies, or a Hybrid
Once the base structure is solid, you build the storage components to fit the interior dimensions of the frame. The two main approaches are drawer boxes on slides or open cubbies with bins.
- Drawer boxes on slides: Build a simple box from 1/2-inch or 3/4-inch plywood and mount it on a pair of drawer slides rated for 100 lbs or more. Precision matters here.
- Open cubbies: If you don’t need the visual polish of drawers, build vertical dividers inside the frame to create compartments. This is cheaper, faster, and more forgiving of slight measurement errors. Bins or baskets slide right in.
Either way, the key is to install the storage components while the frame is still accessible from the sides. If you attach the headboard and footboard first, you’ll struggle to fit the drawers in place.
One common mistake is skipping a rear cross-support. A published plan for a DIY bed frame with storage explicitly adds a removable 2×4 support across the back of the frame to help the drawer system ride smoothly. Without it, the frame can rack—shift out of square—when you pull a heavily loaded drawer open. Add that rear support even if the plan you’re following doesn’t call for it.
Materials, Fasteners, and the Mistakes That Ruin a Build
| Component | Best Material | Why It Matters |
|---|---|---|
| Frame side rails | 3/4-inch plywood or 2×8 lumber | Carries the mattress load and transfers it to the legs |
| Center support beam | 2×4 or 2×6 lumber | Prevents sagging across the bed’s width |
| Slats | 1×4 or 1×6 boards | Supports mattress; spacing under 4 inches prevents sag |
| Drawer boxes | 1/2-inch plywood | Light enough to slide easily; strong enough for contents |
| Drawer slides | Ball-bearing slides, 100+ lb rating | Smooth operation; rated slides last far longer |
| Top surface (if plywood) | 3/4-inch hardwood plywood | Thinner tops flex noticeably under a mattress |
Even with good materials, a few errors can ruin the project. First, never nail into plywood edges without pre-drilling—the plywood will split and you’ll lose the joint. Second, if you use particle board for the frame, one author suggests adding a ¾-inch lumber top for stiffness; particle board alone will sag between supports over time. Third, and most importantly, a bed frame is a structural object. For a DIY build, that means checking your work—tighten everything twice and make sure the frame sits level before you put a mattress on it.
One more point: published assembly manuals are model-specific. The IKEA BRIMNES and NORDLI frames are different systems with different part sets, and you cannot mix their construction methods. If you’re using a manual for reference, pick one design and follow it through.
If the DIY route sounds like more work than you want to take on, a well-reviewed shop-bought frame gets you the same storage with zero assembly headaches. Our tested roundup of the best king bed frame with storage options can help you find one that fits your bedroom and budget.
