How to Build a Solid Wood Storage Bed | Complete DIY Guide 2026

If you shift the mattresses aside, two large storage compartments come into view, accessible via trapdoor lids built into the mattress support platforms. To open them, simply drill a finger-sized hole near the edge—lifting is very easy.

When a bed has a solid structure, you can’t store anything underneath unless you can open it—either from the side (with drawers) or from above, with a lift-up mattress support. This DIY storage bed adopts the latter solution, integrating an additional compartment with a similar system in the shelf-style headboard.

What You Need to Build a DIY Storage Bed

• 28 mm thick spruce laminated board: 1 headboard 500×1760 mm, 2 headboard sides 230×500 mm, 1 headboard lid 188×1760 mm, 2 side panels 300×1930 mm, 1 foot crossbar 300×1760 mm, 1 support beam 280×1902 mm
• 40×40 mm spruce battens: 8 reinforcements (4 corner + 4 for the beam) 255 mm each, 1 headboard lid hinge element 1760 mm
• 25 mm thick poplar plywood: 4 support strips 45×1614 mm, 2+2 fixed and opening mattress support panels 1200×837 and 698×837 mm
• Miscellaneous: 8 dowels Ø 8 mm, PVA glue, 1+2 continuous hinges 1758 and 835 mm, 2 small brackets 15x45x45 mm, screws 2.5×20 mm for hinges, 3.5×25 mm for brackets and mattress supports, 4×70 mm for reinforcements, finishing materials

Double Bed Storage in One Unit

The bed storage and headboard form a single unit, but each is essentially a large box without a bottom and also missing the fourth side. For the storage bed, the missing wall is the front part.

Assembly Tips

Start by cutting all panels to size. Use dowels and wood glue for strong home improvement joints. The frame requires precision: ensure all corners are square before the glue sets.

Joining Systems

For the bed frame, use 8 mm dowels with PVA glue. Reinforce corners with 40×40 mm battens and screws. The mattress support panels sit on plywood strips screwed to the side panels and beam.

Preparing the Connections

Drill dowel holes carefully using a jig for alignment. Apply glue to both surfaces, insert dowels, and clamp until dry. For the headboard hinge, attach the continuous hinge to the lid and the 1760 mm batten.

Mattress Support Platform and Headboard

The fixed and opening mattress support panels are cut from 25 mm poplar plywood. The opening sections have a finger hole for easy lifting. The headboard shelf provides additional storage space—perfect for curtains or extra bedding.

Symmetric Corners

To maintain symmetry, cut all corner reinforcements to the same length (255 mm). This ensures the bed frame remains balanced and sturdy.

Hygiene Considerations

Since the storage compartments are enclosed, they protect bedding from dust. However, ensure the wood is properly sealed with a non-toxic finish. Consider using a rug under the bed to minimize dust accumulation.

The Right Foundation

The mattress support must be sturdy enough to bear weight without sagging. The combination of fixed and hinged panels provides both storage access and proper support. For the best sleep experience, pair this bed with a quality mattress.

FAQ

1. What type of wood is best for a storage bed? Spruce laminated board (28 mm) is recommended for the main structure, with poplar plywood for the mattress support panels. Both are strong and lightweight.
2. Can I add drawers instead of a lift-up top? Yes, but this design uses a lift-up mechanism for simplicity. For a drawer version, you would need to modify the frame and add drawer slides.
3. How much weight can the storage compartments hold? The compartments are designed for lightweight items like blankets, pillows, and duvets. Avoid storing heavy tools or books.
4. Do I need special tools for this project? Basic woodworking tools: circular saw, drill, clamps, and a doweling jig. A home improvement kit will cover most needs.
5. How do I finish the bed? Sand all surfaces smooth, then apply a wood stain or paint. Use a non-toxic, water-based varnish for the interior compartments.

This storage bed combines functionality with clean design. The hidden compartments keep your bedroom tidy, while the solid wood construction ensures durability. For additional bedroom furniture, consider matching nightstands or a dresser to complete the look.
