Build steps

1. 1

   Final Check of Parts and Tools

   ≈ 15 min

   Prepare two pieces of 2x6 lumber for the top board (38×140×900 mm), four pieces of 2x4 lumber for legs (38×89×412 mm), two pieces of 2x4 lumber for aprons (38×89×900 mm), two pieces of SPF lumber 1x8 for bottom boards (19×184×824 mm), two pieces of SPF lumber 1x8 for lid material (19×184×900 mm), two 50 mm hinges, and forty 65 mm coarse-thread screws. Tools include electric driver, saw, measuring tape, carpenter's square, #120 and #240 sandpaper, level, F-clamps, brush, and a sharp saw or trimmer (for hinge mortising).

   Measure

   W 900 mm

   MeasureSTEP 1 / 20

   Tip

   • Hinges are natural color flat 50 mm × 2 pieces, available at home centers for around 300 yen.
   • Be aware of thickness differences between 1x8 lumber (19 mm thick) and 2x4 lumber (38 mm thick); important when selecting screw lengths.

   Watch out

   • The 2x6 lumber top board serves as both seat and lid in this bench, so it differs from a typical top board.
   • Forgetting to purchase hinges prevents lid opening and closing, so always buy hinges beforehand.
2. 2

   Prepare Workspace and Check Lumber

   ≈ 10 min

   Secure a flat workspace of 1500 mm × 1500 mm and cover it with a blue sheet. SPF lumber 1x8 for bottom boards and lid materials (19 mm thick) tend to warp; visually check each piece for warp and decide which side to use.

   Inspect

   No wobble ✓

   InspectSTEP 2 / 20

   Tip

   • SPF lumber 1x8 tends to warp easily. Using the convex side down reduces interference during opening and closing.

   Watch out

   • Using warped bottom boards will cause storage items to tilt. Select boards with warp within 1 mm.
3. 3

   Marking All Lumber

   ≈ 15 min

   Mark cut lines on top board, legs, aprons, bottom board, and lid material. Place two lid pieces side by side to total 1200 mm length, marking hinge mount positions 75 mm inside from the outer edge concurrently.

   Mark a line

   Use a try square

   MarkSTEP 3 / 20

   Tip

   • Standard hinge mounting is 75-100 mm from the lid edge. Mounting too close to the outer edge stresses the lid during opening and closing.

   Watch out

   • Bottom board is 1124 mm wide to fit between legs (1200 - 38 × 2 = 1124 mm). Cutting to 1200 mm causes fitting issues.
4. 4

   Cutting All Lumber

   ≈ 35 min

   Cut two top boards to 1200 mm, four legs to 412 mm, two aprons to 1200 mm, two bottom boards to 1124 mm, and two lid materials to 1200 mm. Using home center cut service for all at once is efficient. When cutting yourself, bundle same-length pieces to cut together.

   Cut

   Use the in-store cut service

   CutSTEP 4 / 20

   Tip

   • Difference between bottom board (1124 mm) and apron (1200 mm) is 76 mm; be careful not to cut both to the same length.
   • SPF 1x8 lumber is thinner than 2x4 lumber (19 mm vs 38 mm), so cutting is quicker due to less blade resistance.

   Watch out

   • Cutting thickness differs between 2x4 and 1x8 lumber; adjust saw blade angle accordingly.
   • Accidentally cutting lid material to 1124 mm (instead of 1200 mm) results in length mismatch; avoid re-cutting if possible.
5. 5

   Sanding All Lumber (#120 then #240)

   ≈ 35 min

   Sand all lumber starting with #120 grit and finish with #240 grit. Sand lid material carefully as it will be sat on. The inner side of lid material (touching storage items) can stop at #120 grit. Lightly round corners to avoid injury from sharp edges, especially for indoor furniture used by children.

   Sand

   #120

   SandSTEP 5 / 20

   Tip

   • Edges where the lid opens and closes can pinch fingers; rounding these corners slightly larger improves safety.

   Watch out

   • Failing to sand the inner side of bottom boards leaves wood dust that could stick to stored items; even light sanding with #120 grit suffices.
6. 6

   Preparing Pilot Holes

   ≈ 20 min

   Drill pilot holes Ø2.5-3 mm for joining legs and aprons (8 holes), bottom boards and aprons (~8 holes), and lids and hinges (4 screws × 2 hinges). For bottom boards, mark screw positions 10 mm up from the lower edge on the apron inside and drill accordingly.

   Drill a hole

   下穴 φ3.5mm

   DrillSTEP 6 / 20

   Tip

   • Use the short screws (Ø3.5 × 16 mm) that come with hinges; 65 mm coarse-thread screws are too long and will penetrate the lid.
   • Countersink hinge screw holes slightly to prevent hinge wobble.

   Watch out

   • Shallow pilot holes for hinges cause hinge instability; countersink a bit deeper.
   • Misaligned pilot holes for bottom boards cause boards to sit slanted; mark symmetrically on both sides.
7. 7

   Assembling One Side Frame

   ≈ 15 min

   Assemble one U-shaped frame with two legs and one apron, securing with four 65 mm coarse-thread screws (two per joint). Position apron 20 mm above leg bottom to support bottom board.

   Build the frame

   Check for square

   AssembleSTEP 7 / 20

   Tip

   • Raising the apron by 20 mm allows the 19 mm thick bottom board to rest on top. Incorrect height prevents bottom board fitting.

   Watch out

   • Setting apron height to typical bench height leaves no space for bottom board insertion.
8. 8

   Assembling Opposite Side Frame

   ≈ 20 min

   Use the first frame as a template to assemble the opposite frame to the same dimensions. Ensure apron height and leg orientation are symmetrical left to right.

   Build the frame

   Check for square

   AssembleSTEP 8 / 20

   Tip

   • Stacking the second frame onto the first for positioning reduces mistakes.

   Watch out

   • Mismatch in apron heights between left and right causes bottom board to settle unevenly; compare both frames before assembly.
9. 9

   Connecting Left and Right Frames

   ≈ 15 min

   Set the two frames parallel at 400 mm depth and connect with the second apron (900 mm). Check diagonals to confirm square before screwing.

   Measure

   W 900 mm

   MeasureSTEP 9 / 20

   Tip

   • The 400 mm depth combined with bottom board width (1124 mm) and two frames (38 mm × 2) results in a total length of 1200 mm as designed.

   Watch out

   • More than 5 mm difference in diagonal lengths causes distortion; adjust before screwing.
10. 10

    Installing Bottom Boards

    ≈ 20 min

    Place two bottom boards (1124 mm) on the inside top of aprons. Leave 3-5 mm gap between boards for dust fall-through and ventilation. Fix bottom boards to aprons using 65 mm coarse-thread screws via pilot holes (4 screws per board, total 8).

    Lay the top board

    5mm 間隔

    Top boardSTEP 10 / 20

    Tip

    • 3-5 mm gaps reduce dust accumulation on stored items.
    • Driving screws from board underside keeps appearance clean; screwing from top shows screw heads inside storage.

    Watch out

    • Driving screws too close to board edges may split wood; place screws at least 20 mm from ends.
11. 11

    Adjusting and Positioning Lid Material

    ≈ 15 min

    Arrange two lid pieces (900 mm) side by side on bench top to fit perfectly. Gap between lid and apron top should be within 2 mm. Lid pieces together total 1200 mm (184 mm × 2 = 368 mm, slightly spaced), designed with an overhang. Position lid 5 mm inset from edges.

    Lay the top board

    5mm 間隔

    Top boardSTEP 11 / 20

    Tip

    • Lid pieces together measure 368 mm depth, leaving 16 mm front and back clearance for 400 mm deep bench.
    • Lid surface to be sat on should face upward; bottom side faces storage.

    Watch out

    • Misaligned lid pieces cause interference when opening and closing; align parallel.
12. 12

    Attaching Hinges

    ≈ 25 min

    Attach two hinges to lid and back apron. Position hinges 75 mm inside from lid edges, spacing two hinges about 300 mm apart. One leaf fixes to lid underside, the other to top of back apron, secured by included screws.

    Build the frame

    Check for square

    AssembleSTEP 12 / 20

    Tip

    • Hinges are typically positioned 75-150 mm from lid edges; hinges mounted too close to lid edge cause cracking from opening/closing stresses.
    • Mask hinges with tape before bending them to ease positioning.

    Watch out

    • Hinge pivots must align exactly at lid and apron joint for smooth operation.
    • Over-tightening hinge screws causes lid to catch when opening/closing; tighten loosely, test movement, then fully tighten.
13. 13

    Testing Lid Opening and Closing

    ≈ 10 min

    Open lid to confirm smooth operation to 90°, without creaking, catching, or interference. Check that lid closes flush with no gaps or lifting.

    Inspect

    No wobble ✓

    InspectSTEP 13 / 20

    Tip

    • Correct hinge pivot alignment ensures smooth 90° lid opening.
    • If catching occurs, slightly trim lid underside or adjust hinge positions.

    Watch out

    • Lid closing rapidly due to gravity risks finger injury; choose hinges with some friction or consider installing dampers.
14. 14

    Optional Lid Opening Stay

    ≈ 15 min

    To prevent lid from closing under its own weight, install an opening stay chain or prop. Attach a ~200 mm chain between back apron inside and lid underside to limit opening to 90° or less.

    Build the frame

    Check for square

    AssembleSTEP 14 / 20

    Tip

    • Using a 300 mm chain and S-hook from a 100-yen shop is a cost-effective solution.
    • Gas dampers provide professional self-close prevention, costing around 2000-3000 yen.

    Watch out

    • Over-tightened or taut chains prevent full lid opening; keep some slack.
15. 15

    Checking Overall Strength and Alignment

    ≈ 15 min

    Close lid and sit on bench, applying body weight. Check for creaks or sagging. Use a level to verify legs and top board (lid) are horizontal. Fix any wobbling by sanding legs or adjusting with height pads.

    Check level

    Level ✓

    LevelSTEP 15 / 20

    Tip

    • Sitting test is essential. If lid deflects more than 3 mm, add reinforcements under aprons.

    Watch out

    • Large lid sag requires central support reinforcement.
    • Painting over wobbly legs leads to paint chipping when legs are sanded later.
16. 16

    Cleaning Before Painting

    ≈ 10 min

    Vacuum and wipe entire bench to remove sawdust and oils. Mask hinges with tape to protect metal parts from paint.

    Inspect

    No wobble ✓

    InspectSTEP 16 / 20

    Tip

    • Paint on metal hinge surfaces looks poor; never forget masking.

    Watch out

    • Paint entering hinge internals stiffens movement; masking is essential.
17. 17

    First Coat of Indoor Finish

    ≈ 30 min

    Apply a thin coat of indoor wood finish (like Watco Oil or Briwax) over entire bench. After 10 minutes, wipe off excess with a cloth. Oil finishes provide a pleasant texture without forming a solid film, suitable for indoor use.

    Paint

    Watco oil / varnish

    PaintSTEP 17 / 20

    Tip

    • Watco Oil requires application, 10-minute soak, then wiping off excess.
    • Briwax yields even more luxurious finish.

    Watch out

    • Skipping wiping leaves sticky residue for several days; always wipe.
    • Using indoor wood finishes can cause odor due to volatile components lasting several days.
18. 18

    Second Coat of Oil Finish

    ≈ 25 min

    After 24 hours drying, apply a second thinner coat (about one-third of first). Wipe off excess again. Dry 24-48 hours after second coat.

    Paint

    Watco oil / varnish

    PaintSTEP 18 / 20

    Tip

    • Second coat uses one-third of first coat amount; color deepens with less material.
    • Always wipe off excess to prevent uneven finish.

    Watch out

    • Neglecting wiping during second coat causes blotchiness.
19. 19

    Removing Masking and Final Checks

    ≈ 10 min

    After oil is fully dry, remove hinge masking tape. Retest lid opening and confirm smooth motion. If needed, lightly apply CRC 5-56 lubricant to hinge pivots for smoother movement.

    Inspect

    No wobble ✓

    InspectSTEP 19 / 20

    Tip

    • Use minimal lubricant on hinge pivots to avoid paint damage.

    Watch out

    • Removing masking before paint is fully dry may peel paint off; wait until fully dry.
20. 20

    Completion and Usage Start

    ≈ 15 min

    Set up the completed storage bench with pet bed. Check final lid operation, seating stability, and storage usability. Test insert long items like shoehorns or umbrellas to verify size fit.

    Done!

    Done — nice work!

    DoneSTEP 20 / 20

    Tip

    • Adding divider boards inside storage helps organization depending on contents.
    • Annual reapplication of thin oil coat restores luster.

    Watch out

    • Leaving lid open stresses hinges on one side, causing loosening; always close after use.
    • Storing damp items deteriorates bottom board; avoid items like laundry.

Warnings

• ⚠️Drill pilot holes before driving screws to prevent wood splitting.
