Built-in wireless charging for custom furniture: a manufacturing guide
Commercial furniture buyers now expect built-in wireless charging as a standard feature in conference tables, desks, and reception counters. The Wireless Power Consortium reported over 1 billion Qi-certified devices shipped by the end of 2025, which means nearly every smartphone a client or employee carries is ready to charge wirelessly. For furniture manufacturers, embedding wireless charging into products is no longer a novelty; it is a specification requirement in a growing share of commercial bids.
Built-in wireless charging for furniture uses Qi-standard transmitters mounted to the underside of surfaces during manufacturing, delivering 5W to 10W of power through wood, laminate, stone, and glass up to 30mm (1.18 in) thick with no routing or surface modification required. The technology is non-destructive, reversible, and compatible with all Qi-enabled smartphones including iPhone 8 and newer, Samsung Galaxy S6 and newer, and Google Pixel 3 and newer. Casework manufacturer Shield Casework has integrated over 250 InvisQi units across 17 production runs since 2021, demonstrating that under-surface charging scales reliably in volume manufacturing.
How OEM integration works in furniture production
Integrating a wireless charger into furniture requires no CNC routing, no drilling, and no modification to the finished surface. The charger adheres to the underside of a tabletop or desk surface using 3M adhesive or security screws during the assembly stage of production. The InvisQi wireless charger measures 12.5cm in diameter and 1.3cm thick, making it small enough to fit inside standard furniture frames, drawer cavities, and cable management channels.
The power cable routes through the furniture leg, pedestal, or cable tray to a standard AC 100-240V outlet via the included 24V power supply. For installations requiring four or more charging points per table, the InvisQi QuadQi quad power supply runs up to four chargers from a single outlet, reducing both cable count and electrical infrastructure needs.
The primary manufacturing constraint is surface thickness. The Qi signal passes reliably through 18mm to 30mm (0.71 in to 1.18 in) of non-metallic material. For iPhone 12 and newer models equipped with MagSafe, the recommended maximum surface thickness is 20mm (0.79 in) for optimal charging alignment. This MagSafe limitation should be communicated in product specifications and end-user documentation.
Surface material compatibility for production
Qi wireless charging signals pass through all common commercial furniture materials except metal. The following table summarizes compatibility across standard production materials:
| Material | Typical thickness | Compatible | Notes |
|---|---|---|---|
| MDF with laminate or veneer | 18mm to 25mm | Yes | Most common commercial furniture material. Optimal range. |
| Solid hardwood | 19mm to 30mm | Yes | Oak, walnut, maple, cherry all work. Verify thickness at charging location. |
| Plywood | 18mm to 25mm | Yes | Standard furniture-grade plywood is within range. |
| HPL (high-pressure laminate) | 18mm to 25mm | Yes | Formica, Wilsonart, Arborite all transmit Qi signals. |
| Corian / solid surface | 12mm to 19mm | Yes | Excellent performance due to thinner standard gauges. |
| Engineered quartz | 20mm to 30mm | Yes | Standard 20mm and 30mm slabs both work. Verify exact slab thickness. |
| Granite / marble | 20mm to 30mm | Yes | Natural stone transmits Qi signals. Confirm no metal mesh reinforcement. |
| Tempered glass | 6mm to 19mm | Yes | Excellent signal transmission. Best performing material type. |
| Metal (steel, aluminum) | Any | No | Metal blocks Qi signals completely. No workaround exists. |
Avoid placing chargers behind metal drawer slides, corner brackets, leveling hardware, or cable management grommets with metal housings. Any metal between the Qi transmitter and the phone surface blocks the charging signal entirely.
Volume sourcing and pricing for manufacturers
Furniture manufacturers ordering 10 or more units qualify for volume pricing, with deeper discounts at 25-unit and 50-unit thresholds. Standard retail pricing for the InvisQi wireless charger is $169 per unit. Request volume pricing directly for production orders. For large runs, suppliers coordinate delivery timing with manufacturing schedules to avoid inventory holding costs.
When quoting projects to clients, add the charger unit cost plus 15 to 30 minutes of installation labor per unit. Most manufacturers find the upsell adds $200 to $300 per charging point to the final product price, with healthy margin on both hardware and labor. For a 20-desk office project, this represents $4,000 to $6,000 in additional revenue on a single order.
Quality control and testing in production
Every charging point should be tested before furniture leaves the shop, using the included LED alignment sensor that confirms signal strength in under two minutes per unit. The testing process is straightforward: place the alignment sensor on top of the surface directly above the charger. All LEDs lit confirms correct alignment and full signal strength. If any LEDs are dark, reposition the charger and retest. This QC step takes less than two minutes and eliminates field service calls.
After verification, apply the included placement sticker to the surface to mark the charging location for the end user. Without this sticker, users will not be able to find the charging sweet spot consistently. For furniture lines where a visible sticker does not match the design aesthetic, consider a small engraved or laser-etched mark instead.
Selling wireless charging as a furniture feature
Commercial furniture buyers in hospitality, healthcare, and corporate office sectors are actively specifying built-in wireless charging in 2026. The feature is invisible until a user places a phone on the surface, which makes it an effective showroom and trade show demonstration. Place a working unit in your display furniture so buyers experience the function firsthand.

Eventscape A+D, a New York-based experiential design firm, has placed 10 orders totaling over 200 units for integration into branded environments and corporate installations. Halcon Furniture, a commercial furniture manufacturer, has ordered across four production runs. These repeat purchase patterns confirm that once manufacturers integrate wireless charging, their clients reorder for new projects.
Frequently asked questions
Does embedding a wireless charger void the furniture warranty?
No. Under-surface Qi chargers attach with 3M adhesive or screws and require no drilling, routing, or modification to the furniture surface, frame, or finish. The installation is completely non-destructive and fully reversible. Removing a unit leaves no damage to the surface.
What phones are compatible with built-in wireless charging through furniture?
All Qi-enabled smartphones are compatible, including iPhone 8 through iPhone 16, Samsung Galaxy S6 through S25, and Google Pixel 3 through Pixel 9. As of 2026, the Wireless Power Consortium estimates that over 90% of smartphones sold globally include Qi wireless charging. iPhone 12 and newer models with MagSafe require surfaces of 20mm (0.79 in) or less for optimal alignment.
Can the charger be serviced or replaced after the furniture is delivered?
Yes. The charger mounts to the underside of the surface and is fully accessible from below. Replacing a unit takes under five minutes with a standard Phillips screwdriver. No disassembly of the furniture is required, and the surface is not affected.
How does under-surface wireless charging compare to routed-in or grommet-mounted chargers?
Under-surface chargers require zero modification to the furniture surface, eliminating CNC routing costs, surface integrity risks, and warranty concerns. Routed-in chargers require machining the surface to within 2mm to 5mm of the top face, which weakens the material and voids most surface warranties. Grommet-mounted chargers are visible, collect debris, and create an opening that compromises spill resistance. Under-surface mounting is the only method that leaves the finished surface completely intact.
