Mount-It! Laptop Tray for Monitor Arm, VESA 75x75 & 100x100, to 16.5 inch Review (2026)

Who it is for

This tray is built for someone who already has, or plans to buy separately, a VESA-compatible monitor arm and wants to mount a laptop on it instead of or alongside a monitor. That setup suits anyone chasing a cleaner desk, since a laptop on an arm can be raised to eye level and swung out of the way rather than sitting flat on the desk surface taking up space. It is aimed at people who move between laptop-only and dual-screen setups, since the tray can be swapped onto an existing arm without buying a dedicated laptop stand. Because the arm is sold separately, it specifically suits someone building or already running an arm-based desk setup rather than someone starting from a bare desk.

VESA compatibility

The tray uses the 75x75mm and 100x100mm VESA hole patterns, which are the two most common spacings used across monitor arms on the market, so it should attach to the large majority of existing arms without needing an adapter plate. This broad compatibility is the main reason to choose a VESA laptop tray over a proprietary laptop arm system, since it lets someone reuse an arm they already own for a monitor and switch it to laptop duty when needed, or run a laptop tray and a monitor on separate arms from different brands. Buyers should still confirm their specific arm publishes one of these two VESA patterns before ordering, since a handful of monitor arms use non-standard mounting.

Laptop fit and security

Adjustable side clips expand to fit laptops up to 16.5 inches wide and retract down to about 9.5 inches, which covers most 11 to 17 inch laptops across major brands rather than only larger models. A lip along the bottom edge and the adjustable clips work together to hold the laptop in place, backed by an integrated safety strap for additional security during tilting, swiveling or height adjustments on the arm. Traction pads add grip against the laptop's base to reduce shifting, which matters more on an arm-mounted tray than a stationary desk stand, since the whole assembly can move when the arm is repositioned.

Ventilation and materials

The tray is built from ventilated steel rather than solid plastic, with air vents cut into the base to let heat escape from underneath the laptop during use, which helps avoid the trapped-heat issue that solid laptop stands can create over long sessions. Steel construction also gives the tray more rigidity than a plastic tray of similar size, which matters when it is cantilevered out on an arm rather than resting flat on a desk. All mounting hardware and instructions needed to attach the tray to a VESA arm are included, so no separate purchase is needed beyond the arm itself.

Value and what to check first

As a way to add laptop mounting to an existing VESA arm setup, this tray is a straightforward and relatively inexpensive option compared with buying a dedicated laptop arm system from scratch. The most important thing to confirm before buying is that the arm being used is rated to support the laptop's actual weight, since the tray itself does not add lifting capacity beyond what the connected arm can hold, and an underrated arm can sag or drift down over time. For anyone with a compatible arm already in hand, this tray is a simple way to get a laptop up to eye level.
