Piano Bench to Storage Ottoman: The Hinge Support Trick
Skip the support strip under the lid and you'll end up with a slammed-shut lid on your fingers instead of a soft-close storage bench.

That wobbly piano bench sitting in your garage or a thrift store corner has a hollow seat cavity just waiting to become hidden storage, but the difference between a bench that works for years and one that pinches fingers or splits its lid comes down to one thing: the support strip you glue and screw along the inside edge of the cavity before you ever touch the hinges. That strip is what the lid rests against when closed and what keeps the hinge screws from ripping out of thin plywood under repeated slamming — skip it, and you're relying on the hinge hardware alone to bear weight it was never designed to carry solo.
What You'll Need
- Thrifted piano bench, $15-30, hinged-lid style preferred
- 1x2 pine support strips, $6, cut to fit inside cavity edges
- Wood glue and 1-inch screws, $5
- Foam padding, 2-inch thick, $12 for a seat-sized piece
- Upholstery fabric, 1 yard, $10-15
- Staple gun and staples, $8 if you don't own one
- Sandpaper and wood stain or paint, $10
- Soft-close hinges (optional upgrade), $8 per pair
How to Build It
- Strip the bench down to bare wood, removing any old finish, padding, or fabric from the seat lid.
- Sand the legs and base smooth, then apply your chosen stain or paint and let it cure fully before reassembly.
- Measure the inside cavity and cut 1x2 support strips to fit along the front and side edges where the lid will rest closed.
- Glue and screw the support strips into place about a half-inch below the top edge, so the lid has a solid ledge to sit on instead of hanging entirely off the hinges.
- Attach new or existing hinges to the lid and back edge, checking that the lid opens fully and closes flush against the support strip.
- Lay the foam padding on top of the lid and wrap it snugly with upholstery fabric, pulling taut as you staple underneath.
- Trim excess fabric and staple the corners neatly so no raw edges show from the sides.
- Load the cavity with blankets or extra pillows and test the lid's swing a few times before calling it done.
Swap in a pair of soft-close hinges for about eight dollars and the lid will ease shut on its own instead of dropping — a small upgrade that makes the piece feel far more expensive than its thrift-store bones.
