Every workshop needs versatile furniture that earns its keep. A dedicated workbench is essential, but for many tasks a smaller, mobile solution is far more practical. The triple-duty stool is exactly that: a compact workshop stool that doubles as a sawhorse for supporting workpieces and, when combined with a simple rolling dolly, becomes a mobile platform for moving materials and tools around the jobsite. Originally featured in Fine Homebuilding, this clever design transforms a single piece of shop-built furniture into a multi-purpose tool that reduces clutter while increasing productivity.
At just 10-1/2 inches tall with a top surface measuring 8-1/2 by 15 inches, this stool is sized perfectly for a range of tasks. Its angled legs provide stability during use and allow it to fit securely onto a custom dolly base. Whether you are sitting while working at a low height, supporting a board for cutting, or rolling a heavy bucket of compound across a room, this design handles all three jobs without taking up the floor space of three separate pieces of equipment. For any home builder or DIY enthusiast looking to maximize a small shop, this project delivers real value.
Design Overview and Key Dimensions
The triple-duty stool is built around a simple box structure with splayed legs. The top platform provides a stable sitting surface while the leg geometry creates a footprint wide enough to resist tipping. When used as a sawhorse, the flat top accepts workpieces securely, and the stool’s low center of gravity keeps everything steady during cutting or assembly.
Core Dimensions
- Top platform: 8-1/2 inches wide by 15 inches long
- Height: 10-1/2 inches from floor to top surface
- Leg splay: Angled outward to create a stable base approximately 12 inches wide
- Dolly base: Cut from a 2×12 board, same length as the stool
- Caster diameter: 2 inches, swivel-type for full maneuverability
Material Selection
Choose straight, knot-free lumber for the stool body and legs. Plywood works well for the top and shelf surfaces because it resists splitting under load and provides a smooth, comfortable sitting surface. For the dolly, a 2×12 dimensional lumber provides the mass needed to keep the assembly stable when rolling. Use exterior-grade adhesives and corrosion-resistant fasteners, especially if the stool will be used in damp conditions such as basements or garages.
For the leg stock, select kiln-dried lumber that is straight and free of large knots. Poplar and pine are excellent choices because they machine well and accept paint or stain evenly. The plywood components benefit from being cut from the same sheet to ensure consistent thickness across the top and shelf surfaces. If you plan to paint the finished stool, fill all screw holes with wood putty and sand flush before applying primer.

Step-by-Step Construction Process
Building the triple-duty stool is a weekend project that requires only basic tools. A circular saw or miter saw, drill, tape measure, and square are sufficient. The following steps cover fabricating the stool body, attaching the legs, and building the rolling dolly.
Fabricating the Stool Body
- Cut the top platform and lower shelf from 3/4-inch plywood to 8-1/2 by 15 inches.
- Cut the side panels from the same plywood. These create the box structure that connects the top and shelf.
- Cut the leg pieces from straight 2×2 or 2×3 stock. Each leg should be cut with the correct angle at both ends so the stool sits level.
- Assemble the box first, using glue and screws. Ensure all corners are square.
- Attach the legs to the corners of the box. Use countersunk screws and waterproof glue. Check that all four legs contact the floor evenly.
Adding the Handle Cutouts
Cut hand-hold openings in the side panels so the stool is easy to lift and carry. A 1-1/2 by 4-inch oval or rectangular cutout centered on each side works well. Sand the edges smooth to prevent splinters. These cutouts also serve as convenient places to hang small tools or clamp workpieces temporarily.
Building the Rolling Dolly
The dolly transforms the stationary stool into a mobile platform. It consists of a 2×12 base board cut to the same length as the stool, topped with a 1×12 spacer board that includes cutouts for the stool’s legs.
| Component | Material | Dimensions | Quantity |
|---|---|---|---|
| Dolly base | 2×12 dimensional lumber | 15 inches long | 1 |
| Spacer board | 1×12 dimensional lumber | 15 inches long | 1 |
| Swivel casters | 2-inch diameter, rubber or polyurethane | Standard plate mount | 4 |
| Mounting screws | #10 x 1-1/4 inch pan head | For caster plates | 16 |
| Deck screws | #8 x 2 inch exterior grade | For spacer attachment | 8 |
Lay out the stool on the 1×12 spacer and mark the location of each leg. Cut out the leg recesses using a jigsaw, making them about 1/8 inch wider than the legs so the stool slides on and off easily. Screw the spacer to the 2×12 base, then mount the casters to the bottom of the base plate. The finished assembly accepts the stool securely while still allowing quick removal when the stool is needed as a stationary workstation.
Pro Tips for Better Results
Clamp the leg assembly together temporarily before driving screws to verify that all four legs contact the floor simultaneously on a flat surface. Any wobble at this stage will be amplified during use. Use a combination square to transfer the leg splay angle consistently from one leg to the next. Pre-drill all screw holes to prevent splitting, especially near the ends of the leg stock.

Using the Stool in All Three Modes
The real value of this design lies in how naturally it transitions between its three roles. Understanding how to use each mode safely and effectively ensures you get the most from the stool.
Mode 1: Workshop Stool
In its simplest configuration, the stool provides a comfortable seat 10-1/2 inches above the floor. This height is ideal for reaching the lower third of wall surfaces, making it perfect for drywall finishing, baseboard installation, and low-level painting. Children can use it to reach bathroom sinks and kitchen counters. The wide top distributes weight evenly, and the splayed legs resist tipping even during shifting movements.
Mode 2: Sawhorse and Work Support
The flat, rigid top makes the stool an effective miniature sawhorse. Use it to support one end of a board while cutting, to hold a workpiece at a comfortable height for sanding, or as a stable platform for a miter saw or small power tool. Pair two stools side by side to create a longer support surface. For even better performance, consider pairing the stool with a set of upgraded sawhorse accessories for additional functionality.
Mode 3: Rolling Dolly and Material Transporter
When placed on the dolly, the stool becomes a low-profile rolling platform. Place a 5-gallon bucket of paint, joint compound, or adhesive on the stool and roll it across the room instead of carrying it. Move small power tools, stacks of tile, or bundles of trim without lifting. The 2-inch swivel casters provide excellent maneuverability in tight spaces. Never stand on the stool while it is on the dolly, as the caster-mounted base is not stable enough for standing. Sitting on the stool while on the dolly is acceptable for low-level tasks such as nailing baseboard.
Workshop Integration and Additional Tips
The triple-duty stool is just one piece of a well-organized workshop. Integrating it with other mobile and stationary solutions maximizes your shop’s efficiency.
Pairing with Mobile Tool Stands
For a fully mobile workshop, combine the stool dolly with mobile tool stands and rolling workbenches. A rolling miter saw stand, a mobile workbench, and the triple-duty stool form a complete portable workstation that can be repositioned anywhere in the shop or jobsite. The stool’s compact size means it can tuck under a workbench or between larger tools when not in use.
Safety Considerations
- Always check that the stool legs contact the floor evenly before sitting or placing weight on the top.
- Never stand on the stool while it is mounted on the rolling dolly.
- Keep the caster mounting screws tight; check them monthly if the dolly is used frequently.
- Do not exceed a load of 50 pounds on the stool when it is on the dolly.
- Apply non-slip pads or rubber feet to the bottom of the legs for use on smooth floors.
Finishing and Maintenance
Apply a coat of polyurethane or varnish to protect the wood from moisture and dirt. A satin or semi-gloss finish stands up well to workshop conditions. Sand all surfaces thoroughly before finishing, paying special attention to edges and corners. Recoat annually if the stool sees heavy use. Store the stool and dolly separately to save space, and keep the casters clean of sawdust and debris for smooth rolling.
