Why Choose a Sit/Stand Desk?

Modern work routines often mean long hours spent sitting, which can lead to fatigue, poor circulation, and posture problems. A sit/stand desk allows for easy movement between sitting and standing, helping to counter these effects throughout the day.

Mark’s desk design balances functionality with style, offering a large work surface, flexible height adjustment, and smart cable management. Plus, by using salvaged walnut pieces, the project stays eco-friendly while showcasing the natural beauty of hardwood.

Materials and Planning

The desktop is built from a collection of walnut offcuts saved over several years. Although inconsistent in thickness and size, the boards are ideal for creating a one-of-a-kind surface full of character.

Height-adjustable legs from FlexiSpot complete the setup, allowing for smooth transitions between sitting and standing. Investing in adjustable legs transforms a traditional workspace into a more dynamic, health-conscious environment.

Preparing the Walnut Boards

Preparation starts with flattening one face of each walnut board using a jointer. Achieving a true surface ensures that the boards will align well during glue-up.

A table saw is then used to rip a parallel edge opposite the jointed side. Running the boards through a planer brings them to uniform thickness, which is essential for creating a clean, flat desktop.

Laying Out and Gluing the Top

With the boards prepped, Mark arranges them on his workbench to find the most visually appealing layout. Priority is given to placing the cleanest edges along the front and back of the desk.

Using a biscuit joiner, he cuts alignment slots between the boards. While the biscuits don’t add structural strength, they help keep the pieces flush during glue-up, simplifying the clamping process.

Building the Desktop in Sections

Because of the limitations of his planer, Mark glues the desktop in two sections before final assembly. Clamping pressure is applied carefully, starting with small clamps on the ends to prevent misalignment.

After the glue dries, the two sections are flattened again and joined together. Any small imperfections or knots are filled with black-tinted epoxy, both strengthening the surface and enhancing the visual appeal.

Sanding and Applying the Finish

Once the epoxy is fully cured, the top is sanded smooth using a progression of grits. Special attention is paid to sanding the end grain, blending it seamlessly into the overall finish.

For protection, Mark uses a brush-on lacquer that dries quickly and creates a tough, attractive surface. While the fumes are strong, the result is a durable and smooth finish perfect for daily use.

Assembling the Adjustable Base

The desk frame is built around FlexiSpot adjustable legs, repurposed from a previous project. Mounting involves pre-drilling holes into the desktop to allow for wood movement, preventing cracking over time.

Cable management is addressed with a mounted tray beneath the desktop. Pilot holes are drilled to simplify attachment, keeping wires neat and organized for a cleaner final look.

Final Assembly and Setup

After carrying the components inside, Mark assembles the frame and attaches the desktop from underneath. Cables are routed neatly through the tray, with only a single power strip left visible for easy access.

The end result is a sturdy, polished sit/stand desk that’s both functional and visually appealing. Katie now has a spacious work surface that encourages movement and fits seamlessly into her office.

A Practical and Rewarding Build

Building a sit/stand desk from scratch offers an opportunity to create a workspace tailored to individual needs. Mark’s project demonstrates how woodworking skills can be used to improve everyday life in practical ways.

The combination of salvaged walnut, strong joinery, and attention to ergonomic details makes this project not just beautiful, but lasting. It’s a great reminder that functional builds can still showcase creativity and craftsmanship.
