What You'll Learn

Designing the tabletop
Materials and Costs:
When designing the tabletop, consider your budget and the materials you want to use. You can find solid wood tabletops at IKEA, such as the IKEA tabletop, which costs around $80. Alternatively, you can source wood from home improvement stores like Home Depot, where you can find premium pine for about $50. Keep in mind that cheaper options may be warped and might not provide the straight edges desired for a sturdy tabletop.
Size and Shape:
The size and shape of your tabletop will depend on your personal needs and space constraints. If you require a large surface for multiple monitors, keyboards, and other equipment, opt for a larger tabletop. Consider the shape as well—you can go for a traditional rectangular shape or explore options like L-shaped designs to maximize space and functionality.
Stability and Smoothness:
Stability is a critical aspect of your electric height-adjustable desk. Ensure that your tabletop is securely attached to the base and legs. Consider using pocket hole screws and washer-head wood screws for a sturdy attachment. Additionally, pay attention to the grain direction of the wood. Alternating the grain direction when pairing up boards can enhance stability and minimize warping. If you're using plywood, ensure the top bracket and plywood move away from the desktop without any additional stress, as plywood might not stay in sync with the actuators over time.
Aesthetics:
Think about the aesthetic you want for your tabletop. You can choose to match the existing style of your room or create a focal point by using a contrasting color or stain. If you plan to place heavy equipment on the desk, consider adding a discreet wireless charging station underneath to manage cables neatly.
Customization:
You can customize your tabletop further by adding a foam pad underneath speakers to enhance sound directionality. Additionally, consider adding a shelf underneath for additional storage or a printer. Drilling a large hole in the tabletop to mount the switch for height adjustment is also a useful customization, allowing for snag-free movement.
Remember to take accurate measurements and plan the assembly process carefully to ensure all the components of your electric height-adjustable desk work harmoniously.

Sourcing materials
Electric Base/Actuators
The electric base or linear actuators are the key components that enable the height adjustment of your desk. You can find these online, with eBay and Amazon being popular choices. The cost of these actuators can vary, with prices ranging from $150 to $500, depending on the quality and speed you desire.
Wood
For the desktop surface and legs, you will need wood. Consider using birch or oak plywood for the desktop, which can be purchased from hardware stores or wood suppliers. Ensure the thickness meets your desired weight and stability requirements. For the legs, straight-edged wood is preferable, and you can find premium pine options at stores like Home Depot for around $50.
Screws and Fasteners
A variety of screws and fasteners will be needed to assemble your desk. This includes wood screws for attaching the desktop and pocket hole screws for connecting the stretcher between the legs. You may also require nails and a nail gun for certain assembly steps.
Power Supply
Your electric desk will require a power supply, typically a 12VDC power supply, which can be purchased online or at electronics stores.
Tools
Assembling your desk will require a range of tools, including a drill, clamps, wire cutters, a stapler, and a saw for cutting the wood to size. You may also need a jigsaw and sandpaper for creating smooth edges and holes in the desktop.
Desktop Surface
If you are not creating your own desktop surface from wood, you can purchase ready-made tabletops from IKEA or other furniture retailers. Ensure the size and shape match your desired specifications.
It is important to note that you may not need to source all of these materials if you are adapting an existing desk. You can also customise your desk with additional features, such as a wireless charging station or cable management system.

Building the legs
Planning and Materials
Begin by deciding on the height range you desire for your desk. Measure and plan the dimensions of the legs, ensuring they align with the height requirements. Source the necessary materials, including wood for the legs, plywood for the tabletop, and linear actuators for height adjustment. Consider the weight capacity you require and choose actuators rated for your needs.
Assembly
Using your chosen wood, cut the pieces to size for the leg assembly. Follow any instructions provided with your actuators for proper installation. Mount the linear actuators to a small wooden base, ensuring they are secure and level. Build the inner column around the actuators, and then construct the outer column. Test the strength of one leg assembly to ensure it can bear the required weight.
Installation
Once both leg assemblies are complete, install them onto your desk frame. Mark the height of the actuators' lowest position to ensure the legs are synchronized when lowered. Drill holes in the tabletop to accommodate the moving table legs. Sand the edges of the holes to prevent snags and ensure smooth movement. Attach the tabletop to the legs using screws or other recommended fasteners.
Testing and Adjustment
Test the height adjustment mechanism by powering up the actuators and ensuring they work smoothly in unison. Fine-tune the synchronization as needed by adjusting the actuator settings or physical positioning.
Finishing Touches
Sand and finish the legs to match the aesthetic of your workspace. Consider staining or painting the legs to enhance their appearance and protect the wood. Add any final touches, such as cable management solutions or wireless charging stations, to complete your adjustable electric desk.

Attaching the tabletop
One popular method is to use screws to attach the tabletop to the legs or base. If you're using plywood for your tabletop, as many DIYers do, you'll want to drill holes in the plywood support and then drive in washer-head wood screws. This will ensure a secure fit and allow for seasonal wood movement. It is important to note that if you are using an IKEA tabletop, most of them are made of cardboard, so drilling legs into it may not provide the strongest hold.
Another approach is to use a combination of glue and nails. You can glue and nail additional pieces of wood to the tabletop base to make the sides thicker and provide a more secure attachment point for the legs. This method can add stability and ensure that your tabletop can withstand the weight it will bear.
When attaching the tabletop, it's essential to consider the height of your desk. You'll want to adjust the legs to your desired sitting height before securing the tabletop in place. This may involve measuring and marking the leg positions on the tabletop before attaching it.
Additionally, you may need to cut holes in the tabletop to accommodate the moving table legs. This is especially important if you want your desk to have a wide range of height adjustments. Mark the position of the legs on the tabletop and cut holes that will allow the legs to move freely without catching.
Finally, if you're adding a switch to control the height adjustment, you'll need to drill a hole in the side of the tabletop to mount the switch. Run extra wire through this hole to ensure the desk can rise without snags.
By carefully following these steps and choosing the right attachment method for your tabletop, you'll be well on your way to enjoying the convenience and flexibility of your new electric height-adjustable desk.

Finishing touches
Once you've built your electric height-adjustable desk, there are a few finishing touches you can add to perfect your setup. Here are some ideas to consider:
Stability and Levelling
It's important to ensure that your desk is stable and level, especially if it's an electric model. You don't want it to be wobbly or unsteady, as that could lead to accidents or damage. Check that the desk is firmly attached to the base and that the legs are secure and evenly adjusted. Use a spirit level to check for evenness, and adjust the leg heights or consider adding small levelling feet if necessary.
Cable Management
A desk with good cable management looks neat and tidy, and it also helps to prevent accidents and damage to your equipment. There are various cable management solutions available, such as cable trays, clips, or channels, that can help you organise and conceal your cables. You can also consider adding cable management holes or cut-outs in your desktop to allow cables to pass through neatly.
Wireless Charging
For a modern and convenient touch, you could install a wireless charging pad or station for your smartphone or other compatible devices. This would allow you to simply place your device on the charging spot, eliminating the need for extra cables and keeping your desk clutter-free.
Sound Quality
If you use speakers on your desk, consider adding a foam pad underneath them to direct the sound towards your ears. This will prevent the sound from bouncing off the desk and reducing audio quality. This simple addition can greatly improve your listening experience and reduce noise distractions for others around you.
Custom Height Programming
If your electric height-adjustable desk doesn't already have this feature, consider adding a control system that allows you to program custom height settings. This way, you can set your favourite heights for sitting and standing, and adjust the desk with just the push of a button, without having to hold it down.
These finishing touches will help you create a functional, comfortable, and aesthetically pleasing workspace. Enjoy your new electric height-adjustable desk!
