Window Seat with Storage

This project creates additional seating while helping you keep the room neat and tidy.

Difficulty: Difficult

2 shelving units or bookcases (can be purchased at most big-box stores)
Tape measure
2 sets of 4" bench legs
(4) 1" wood screws
(8) 2" wood screws
Drill driver
Irving clamps
Protective eyewear
Circle saw
T-square or regular straight edge
½ CDX plywood and high-density furniture-grade foam
Quilt batting
Spray adhesive
2½ yards of fabric
Staple gun

  1. Use the tape measure and pencil to mark about 1" in from the short edge of the bottom of the shelving unit. Repeat this step in each corner. This is where the feet will be placed
  2. Predrill holes into the marks from step 1. Be sure to wear gloves and protective eyewear

  3. Carpenter Tip: Measure the screws of the feet against the drill bit to find the length. Mark the same length on the drill bit with painter’s tape so the depth of the feet will be drilled.

  4. Once the holes are drilled, screw in the feet

  5. Repeat steps 1 through 3 for the second bookcase
  6. Next, flip both bookcases onto their feet and line them up. Clamp them together so they are flush, with no space between them

  7. On the inside of the first bookcase, about ½" in from the edge and 4" up from the shelf, drill a hole through both bookcases and secure them together with a wood screw

  8. Repeat step 6 for the remaining three corners
  9. Now it’s time to cut the plywood, which will act as a base for the cushion. Measure the plywood so that it is the same size as the length and width of the bookcase
  10. Cut the plywood to the right dimensions with a saw

  11. Carpenter Tip: If you don’t own a circular saw or don’t feel comfortable using one, you can always take the dimensions to a hardware store and have the plywood precut.

  12. Measure the fabric to the wood, leaving about 4" excess on each side
  13. Measure and cut the foam and quilt batting to the size of the wood
  14. Using a spray adhesive, generously spray the plywood and the foam, and then lay the foam onto the plywood and press down slightly. Let it rest for about 1 minute

  15. Repeat this step with the foam and the quilt batting, again letting it rest for about a minute
  16. Lay the fabric across the quilt batting. Carefully turn it over so the plywood is now facing up
  17. Fold the fabric over, pulling slightly and making sure the fabric is nice and snug. Starting from the center and working out, secure the fabric to the plywood with a staple gun, stapling about every 4". Fold the corners like a gift and staple in place

  18. Flip the plywood over again so the fabric is now on top
  19. Lay the bench cushion flat on the bookcase. If the plywood is bending towards the center, that’s okay – we’ll take care of that in the next step

  20. Drill the remaining screws through the top inside of the bookcase to secure the bench to the bookcase

  21. Enjoy the new seating and storage unit
