This step stool we designed is also a toolbox. More than that, it's sturdy enough to support a big guy or gal.

While your ordinary step stools offer little in the way of support for bigger guys and gals, we designed our step stool to easily hold weight. We also added a storage compartment for tools or supplies.


Use 19mm laminated pine shelving and 44 x 44mm pine
to make our step stool with storage compartment. Make as is, or modify the dimensions to increase the length of the steps, or even to add another step.

Small step:

4 of 44 x 44 x 130mm - legs

2 of 44 x 44 x 280mm - top rail

2 of 44 x 44 x 192mm - leg rail

3 of 22 x 94 x 340mm - top slats

Large step:

4 of 44 x 44 x 330mm - legs

2 of 44 x 44 x 280mm - top rail

2 of 44 x 44 x 192mm - leg rail

3 of 32 x 94 x 452mm - top slats

Storage compartment:

2 of 19 x 364mm x 123mm lam pine - compartment front/back

2 of 19 x 123 x 192mm lam pine - compartment sides

1 of 19 x 192 x 326mm lam pine - compartment base

1 pair 250mm ball-bearing drawer runners and 16mm screws

2 of full-overlay concealed hinges plus 16mm screws

4 x 40mm smooth shank screws [18]

4 x 60mm smooth shank screws [14]

35mm Forstner bit

Wood glue

Wood stain, sealer or varnish and paintbrush


Drill / Driver plus assorted bits

Orbital sander plus 120- and 180-grit sanding pads

Quick clamps

Tape measure and pencil


1. Arrange the pieces for the storage compartment and assemble using wood glue and [40mm] screws.

2. To assemble the small step stool, drill 3mm countersunk pilot holes through the side rail into the legs. Join with wood glue and [60mm] screws.

3. Repeat step 2 above to join the legs for the large step stool.

4. Measure up 41.5mm on the legs - for both the small and large step stool - and use this as a guide for mounting the leg rail.

5. For both the small and large step stool, glue together the slats that form the tops/lid.

6. Small step stool: Glue the legs to the slat seat.

7. Turn the stool over to drive [60mm] screws through the top into the leg assembly on both sides.

8. Large stool: With the storage compartment upside down, glue the leg assemblies onto the side of the compartment. Pre-drill countersunk holes through the leg assembly into the compartment and secure with 60mm screws.

<p>This is genius and easy enough to make in the makeshift shop in my garage! Great design. :)</p>
<p>I downloaded this to my things to do Folder. Not sure when I will get </p><p>A-Round-Tuit. Need to make one of those also! This is a nice simple</p><p>thing to teach to my Church group kids that come over.</p>
<p>Nice idea for an &quot;all-in-one&quot; household solution. I guess my only upgrade to it would be a flush grab handle in the lid and side clips to keep the lid closed while carrying.</p>
Very nice! Voted for it...
<p>Cool project and excellent 'ible! :D</p>
Excellent project.
