A wooden storage ottoman is a useful weekend project: it adds a seat, hides blankets or toys, and can be sized to fit a specific room. This version uses a simple plywood box, a hinged lid, and a removable upholstered cushion. It is sturdy enough for normal seating without requiring advanced joinery.

Project Overview
The finished ottoman is approximately 24 inches wide, 16 inches deep, and 18 inches high, including the cushion. Adjust the dimensions to suit your space, but keep the proportions in mind. A box that is much taller than it is deep can feel unstable, while a very shallow box will hold little.
| Material | Advantages | Trade-offs |
|---|---|---|
| 3/4-inch plywood | Strong, stable, and easy to paint | Visible edge layers need edging or filler |
| Solid pine boards | Attractive edges and easy to stain | More likely to move, cup, or dent |
| 1/2-inch plywood | Cheaper and lighter | Needs internal cleats or framing to prevent flexing |
For most first-time builders, 3/4-inch plywood is the sensible choice. Cabinet-grade plywood gives cleaner faces, but inexpensive sanded plywood is adequate if you plan to paint. Avoid heavily warped sheets; a warped panel will make the lid and corners difficult to align.
Materials and Tools
You will need one 4-by-8-foot sheet of 3/4-inch plywood, or enough offcuts for two sides, two ends, a bottom, and a lid. Add 1-by-2 boards for interior cleats, 1 1/4-inch wood screws, wood glue, two or three soft-close or toy-box hinges, and sandpaper. A pair of soft-close toy box hinges is safer than ordinary butt hinges because it prevents the lid from slamming shut.
For the cushion, buy a piece of 2-inch medium-firm upholstery foam, quilt batting, and durable upholstery fabric. A medium-firm upholstery foam is a better choice than mattress foam, which can feel too soft and collapse at the edges. Useful tools include a circular saw or table saw, drill, countersink bit, tape measure, square, clamps, staple gun, and a random-orbit sander.
Cut List
Cut the parts to these dimensions:
- Two side panels: 16 by 17 1/4 inches
- Front and back panels: 22 1/2 by 17 1/4 inches
- Bottom panel: 22 1/2 by 14 1/2 inches
- Lid panel: 24 by 16 inches
- Four interior cleats: 14 inches long
The front and back fit between the side panels. The bottom sits inside the box, leaving a 3/4-inch margin around its edges. This layout makes the outside dimensions close to 24 by 16 inches. Measure your actual plywood thickness before cutting. Nominal 3/4-inch plywood can vary, and small errors compound quickly.
Build the Storage Box
Start by sanding the panel faces and lightly easing the sharp edges. Apply glue to the mating edges of one side and the front panel. Clamp them at 90 degrees, check with a square, then drill pilot holes and drive screws from the side panel into the edge of the front panel. Place screws about 3 inches apart and keep them at least 3/8 inch from the plywood edges.
Attach the back and second side in the same way. Check the diagonals of the open box. If both diagonal measurements are within 1/8 inch, the box is square enough for this project. If one diagonal is longer, push the long corner inward before the glue sets.
Install the bottom next. Add glue to the lower edges, position the bottom panel flush with the lower edge, and screw through the sides and ends into the bottom. For extra strength, glue and screw the 14-inch cleats inside the box along the lower side edges. These cleats provide more material for the bottom screws and reduce racking.
Do not skip pilot holes. Driving screws directly into plywood edges can split the outer veneer or force the layers apart. If a screw head breaks through, remove it and repair the hole with wood filler rather than leaving a sharp point inside the storage compartment.
Prepare the Lid and Cushion
Center the lid on the box and mark the hinge locations. Before installing hinges, sand the lid corners and test its movement. The lid should overhang the box evenly by about 3/4 inch on every side. Install the hinges according to their instructions, then open and close the lid several times. A lid that binds usually means the box is slightly out of square or a hinge is not aligned.
For the cushion, place the lid upside down on the foam and trace around it. Cut the foam to the lid size with a sharp bread knife or an electric carving knife. Cut batting large enough to wrap over the foam and around the lid by about 3 inches. Cut fabric with an additional 3 inches beyond the batting on all sides.
Lay the fabric face down, add the batting and foam, then place the lid on top with the finished side facing upward. Pull the fabric firmly over one edge and staple it underneath. Staple the opposite edge next, followed by the remaining sides. Work from the center toward the corners, alternating sides to keep the fabric tension even. Fold the corners neatly and trim excess material so it does not interfere with the hinges.
Finish and Safety Checks
Fill screw holes, sand through 120 and 180 grit, and remove dust before finishing. Paint is the most forgiving option for ordinary plywood. If staining, use a pre-stain conditioner or test on an offcut first; plywood faces can absorb stain unevenly. A water-based clear coat dries quickly and is suitable for a living room ottoman.
Install adhesive felt furniture pads underneath if the ottoman will sit on hardwood. For carpet, pads are optional. Add a small latch only if you need the lid to stay closed; a basic magnetic catch is cheaper, but it can make the lid harder for children to open. If children will use the ottoman, use safety hinges and avoid a lid that can trap fingers.
Finally, test the ottoman with gradually increasing weight. Sit near the center, then near each corner, and watch for flexing, loose screws, or hinge movement. The cheaper 1/2-inch plywood option is fine for a lightweight footstool when reinforced with a 1-by-2 frame, but 3/4-inch plywood is worth the added cost for regular seating and heavier storage.
