A TV lift cabinet should be designed around the lift path from the start. Moving covers, slats, cable loops, service access, and lid clearance matter as much as the lift itself.
Guide the load properly — the actuator should provide motion, not become the guide, the bearing, and the stop.
What is the real mechanism?
The first job is to identify how the load moves. Is it lifting vertically, rotating around a hinge, sliding on rails, or moving through a linkage? That mechanism decides the force math.
What should you check before ordering?
Check moving load, stroke, closed length, extended length, speed, duty cycle, voltage, current, brackets, control method, and physical access for service. Do not order from force alone.
What should the first-pass inputs be?
Use the calculator only as a first-pass check. The final design still depends on geometry, hardware, wiring, and safety.

A TV lift cabinet fails when the cabinet design ignores the mechanism. The lift needs vertical clearance, cable bend space, lid clearance, ventilation, and a structure that does not flex when the TV starts moving.
Where would you use this?
Use TV lift cabinets in living rooms, bedrooms, boats, RVs, conference rooms, and outdoor covered spaces where you want the screen hidden until needed. The same logic applies to monitor lifts and projector accessory lifts.
How would you use it in a real build?
Measure the screen, mount, and lift together. Add clearance above the TV so the screen does not hit the lid. Leave room behind the screen for HDMI, power, and service loops. Bolt the lift to a rigid cabinet base, not a thin decorative panel.
What is a realistic example?
A 43-inch TV is 22 inches tall. The lift carriage adds 3 inches below the mounting point, and the cabinet top is 1 inch thick. You need more than 26 inches of internal height before allowing for cable bend and top clearance. A cabinet that measures exactly 26 inches inside will feel perfect on paper and frustrating in the shop.
"The cabinet is the shell around the moving envelope, not the other way around. Design the lift travel first — the stroke, the lid clearance, the cable loop — and let the woodwork follow that envelope. Every cabinet I've seen fail started as furniture that tried to swallow a lift afterward." — Robbie Dickson, Founder and Chief Engineer of FIRGELLI Automations
What usually goes wrong?
The common mistake is designing the furniture first and forcing the lift in later. Start with the lift travel envelope. Then design the cabinet around the moving screen, not just the visible woodwork. The 5 failure modes below show up repeatedly in DIY TV lift cabinet projects:
- Cabinet built first, lift forced in afterward. Internal height ends up too short, and the TV collides with the lid on close. The fix is to design the cabinet around the lift travel envelope from the start.
- Internal height measured to the TV alone. The carriage depth, lid thickness, and cable bend radius all add height. A cabinet sized to the bare TV will bind on the lid or pinch the cables on the first cycle.
- Lift bolted to a thin decorative top panel. The panel flexes as the TV starts moving, and that flex becomes side load on the actuator rod. Mount the lift to a rigid base or structural frame, not to trim.
- No cable service loop. HDMI and power cables tension at full extension and pull connectors loose over repeated cycles. Leave a deliberate loop of cable with strain relief at both ends.
- No service access. Replacing the actuator should not require dismantling the furniture. Leave access to the lift bolts, wiring, and connectors before the cabinet is glued and finished.
What should you measure before choosing parts?
Measure TV height, lift stroke, cabinet internal height, cable bend radius, lid thickness, and service access. Add the VESA bracket and any soundbar or trim before you commit to cabinet dimensions. The moving envelope matters more than the TV size printed on the box.
How should you test it before trusting it?
Test the mechanism at the 2 worst positions: the highest load position and the tightest clearance position. Run it at least 20 full cycles before you judge it. Listen for speed changes, bracket flex, cable rub, and any point where the actuator rod stops moving in a straight line.
Then test it with the real load, not a hand pushing on the frame. A mechanism that works empty can bind once the mattress, TV, hatch, motor, or patient load gets added.
What changes when this becomes a real product?
A one-off build can tolerate adjustment. A real product cannot. Production needs slotted brackets removed or locked down, repeatable hole locations, controlled wire routing, service access, and a clear failure mode. If a user can overload the system, the control system should detect it before the hardware bends.
What rule of thumb should you remember?
Make the structure guide the load and make the actuator provide motion. When the actuator also becomes the guide, the bearing, and the stop, the design starts eating itself.
Which applications are a good fit?
Good applications include living-room hidden TVs, end-of-bed cabinets, yacht furniture, RV cabinets, boardroom screens, and monitor lifts in desks. The common thread is controlled motion. The load should move through a known path, with brackets, guides, hinges, or structure carrying the side loads.
What details should go on the design checklist?
Before choosing hardware, write down TV height, lift stroke, cabinet depth, lid path, cable bend radius, ventilation, remote receiver location, and access to the lift bolts. These numbers and conditions stop the project from turning into guesswork. They also make support conversations much faster because the important facts are already on the table.
For a prototype, you can adjust brackets and reroute wires after the first test. For a finished installation, make those decisions early. Leave access to fasteners. Leave access to wiring. Leave enough room to replace the actuator without taking the whole project apart.
What is the practical takeaway?
Design the moving TV envelope first. The cabinet is just the shell around that envelope.
What final check should you do before ordering?
Write the project down as 5 numbers before you buy anything: load, stroke, speed, voltage, and available mounting space. Then add the real-world conditions: water, vibration, dust, heat, access, duty cycle, and what happens if the mechanism jams. This 10-minute check catches most actuator mistakes before money gets spent.
After that, check the control path. The switch, relay, controller, fuse, wire, and power supply all need to match the actuator current. A strong actuator with weak wiring is still a weak system.
