A wooden storage chest is a useful first furniture project: it has a simple box shape, forgiving dimensions, and enough room to practice square assemblies, sanding, and finishing. Adding soft-close hinges makes it safer around children and prevents the lid from slamming. The hinge choice does add a little measuring and adjustment, so build the box accurately before installing the hardware.

A beginner-friendly chest plan
This plan produces a chest about 36 inches wide, 18 inches deep, and 20 inches high, including the lid. That size works for blankets, toys, shoes, or seasonal clothing without becoming too heavy to move. Adjust the width in 3-inch increments if you need a different size, but keep the depth moderate. A very deep chest is harder to reach into and puts more leverage on the hinges.
| Part | Quantity | Suggested material | Finished size |
|---|---|---|---|
| Front and back | 2 | 3/4-inch plywood or pine panels | 36 x 18 inches |
| Ends | 2 | 3/4-inch plywood or pine panels | 16 1/2 x 18 inches |
| Bottom | 1 | 1/2-inch plywood | 34 1/2 x 16 1/2 inches |
| Lid | 1 | 3/4-inch plywood or a glued-up panel | 36 x 18 1/2 inches |
The end pieces fit between the front and back, while the bottom fits inside the four walls. This layout is straightforward to cut and leaves the front and back edges covering the end-grain edges. If your plywood is exactly 3/4 inch thick, the listed measurements should work. Measure the actual sheet thickness before cutting; nominal plywood can vary by several hundredths of an inch.
Materials and tools to buy
Use cabinet-grade plywood for the cleanest result, or select straight, knot-free pine boards if you prefer a painted chest. Construction plywood is cheaper but often has voids and rough faces that show through paint. For a quick utility chest, it is perfectly acceptable after filling and sanding.
You will need wood glue, 1 1/4-inch screws, sandpaper from 120 through 220 grit, and a finish. A pocket-hole jig kit is an easy joinery option, although simple butt joints with glue and screws also work. Add a countersink bit so screw heads sit slightly below the surface.
For the lid, buy two or three soft-close chest hinges rated for a lid at least as heavy as yours. Two hinges suit a lightweight plywood lid. A solid hardwood lid or a chest wider than 36 inches is better with three. Check the hinge’s opening angle and mounting depth before cutting any recesses.
Cutting and preparation
Break down the panels with a circular saw and a straightedge, or use a table saw. Clamp a guide firmly and make one clean pass rather than correcting a wandering cut. Label every part immediately. Small differences in width can be corrected, but confusing the front with the back or flipping a panel can create an uneven lid reveal.
Dry-fit the four walls on a flat surface. Measure diagonally from corner to corner in both directions. The measurements should be within 1/8 inch of each other before you attach the bottom. If the diagonals differ more than that, the box is out of square and the lid may bind or leave an uneven gap.
Sand the inside faces now, while they are easy to reach. Start at 120 grit and finish at 180. Ease sharp exposed edges with two or three light passes of sandpaper. Do not heavily round the top edges; soft-close hinges need flat, consistent surfaces.
Step-by-step chest assembly
Apply a thin, continuous bead of glue to each mating edge. Clamp the front, back, and ends together, then check the diagonals again. Drill pilot holes and install screws every 6 to 8 inches. If using pocket holes, place them on the inside faces and keep them at least 2 inches from each corner to reduce splitting.
Once the walls are secure, check that the bottom fits without forcing it. Apply glue to the lower edges, set the bottom in place, and screw it to the walls every 6 to 8 inches. Keep screw heads flush or slightly recessed. Wipe away squeeze-out with a damp cloth, but avoid soaking unfinished plywood edges.
For extra strength, glue 3/4-inch square cleats inside the lower corners. Cleats are especially worthwhile if the chest will hold books or tools. They also give the bottom more support than screws driven into thin plywood edges.
Fitting the lid and soft-close hinges
Place the lid on the chest and aim for a 1/16-inch gap on the sides and front. A 1/8-inch rear gap is safer if the hinge barrel needs clearance. Clamp the lid in position with thin cardboard spacers, then mark the hinge locations. Keep the outer hinges about 3 inches in from each side; place a third hinge centered between them.
Do not rely on the screws to pull a misaligned hinge into place. Mark pilot holes with an awl, drill them slightly smaller than the screw cores, and install the hinges loosely at first. Open and close the lid several times before tightening everything. If the hinge instructions call for a routed recess, make it shallow and test-fit often. Removing too much material can leave the hinge loose and difficult to align.
A soft-close hinge can still let a lid slam if it is overloaded, installed at the wrong angle, or adjusted beyond its intended range. Test the lid from several positions. It should slow during the final few inches without needing excessive force. Add a separate lid stay if you need the lid to remain open; do not use the soft-close mechanism as a prop.
Finishing and seasonal use
Fill visible screw holes with wood filler, let it dry, and sand the repairs flush. For paint, apply primer to all faces and especially to plywood edges. Two thin topcoats are more durable than one heavy coat. For a clear finish, use water-based polyurethane for low odor and quick drying, or oil-based polyurethane for a warmer color and longer working time.
Finish the inside as well as the outside. Unsealed wood absorbs humidity, which can swell the lid and cause hinge binding. In spring and summer, apply finish in a shaded, dry area and allow the stated drying time before closing the chest. In damp fall or winter conditions, allow extra curing time and avoid storing textiles until the finish no longer smells.
Before loading the chest, add felt pads under the base and test it on the floor where it will live. Recheck hinge screws after a week. If the lid rubs, first look for a loose screw or a warped panel; tightening the hinges is often enough. If a child may use the chest, install a finger-safe gap solution or a dedicated safety hinge rather than assuming soft-close hardware eliminates every pinch hazard.
