The ProShield™ Laptop Tray is a barrier you place between a laptop and your lap. It does two practical things: it adds a cooler, more comfortable layer against heat, and it puts shielding material—silicon steel and aluminum—between the laptop’s underside and you. It does not make a laptop emission-free, and this page explains honestly what it does and does not do.
If you often work with a laptop on your lap or in bed, this is the context you need before buying. For the background on why lap use is worth addressing at all, see laptop on your lap: heat, EMF and simple fixes.
What it’s made of
Per the product specification, the tray combines:
- Non-grain-oriented silicon steel and a high-conductivity aluminum sheet—the shielding layers.
- Closed-cell polyethylene foam—for comfort and heat reduction against your lap.
The product page reports independent laboratory testing of its shielding up to 20 GHz, and links the lab results for anyone who wants to read them. We present those as the lab’s findings for the tested configuration, not as a medical claim.
What it does
- Adds distance and a heat barrier. The foam layer keeps laptop heat off your skin—the clearest, best-documented benefit of not resting a laptop directly on the lap.
- Reduces fields passing downward through the tray. The steel-and-aluminum layers sit in the path between the laptop’s underside and your lap.
What it does not do (the honest part)
- It does not make a laptop “radiation-free.” The device still emits from its sides, keyboard and screen, and its Wi-Fi and Bluetooth still transmit.
- It shields the path through the tray—toward your lap—not the whole room.
- It is not a medical device and makes no claim to prevent illness. EMF from laptops is non-ionizing; see what EMF is.
Who it’s for
It fits people who spend long stretches with a laptop on the lap or in bed and want a cooler, more comfortable surface with a shielding layer built in—rather than balancing a hot laptop on bare skin. If your main concern is simply heat and comfort, any firm lap desk helps; the ProShield adds the shielding layers and the published testing for people who want that too.
Common questions
Does the ProShield tray block all EMF?
No. It reduces what passes through it toward your lap and keeps heat off your skin. The laptop still emits from other surfaces and its radios still transmit.
Is it a health or medical product?
No. It is a comfort-and-shielding accessory. Laptop EMF is non-ionizing, and we make no disease-prevention claim.
Do I need it, or is a plain lap desk enough?
For heat and comfort alone, a firm lap desk helps. The ProShield adds silicon-steel and aluminum shielding layers and published lab testing for those who want a barrier as well.
