Large Keyboard Tray Under Desk Pull Out Keyboard & Mouse Tray - Extra

Our review of the Large Keyboard Tray Under Desk finds this tray best suited for home office users and casual gamers who need to reclaim desktop space and want a sturdy, no-drill installation. The single biggest reason to buy is the extra-large 25.6 x 11.8 in platform (31.5 in including clamps) that comfortably fits a full keyboard and mouse while freeing the desktop. Installation is straightforward for desks with a flat, unobstructed underside, and the heavy-duty adjustable C-clamps make it usable on thicker desks without permanent modification.

Key Features

• Extra-large surface: The 25.6 x 11.8 in tray provides room for a keyboard, mouse and small accessories so the desktop stays clear and organized.
• Adjustable C-clamps: Heavy-duty clamps fit desks up to 2.76 in thick, offering a secure hold without drilling and protecting surfaces with thick non-slip pads.
• Smooth glide design: The sliding rail system pulls out smoothly up to 7.8 in for quick access and stores quietly when tucked away.
• Ergonomic typing angle: The tray places keyboard and mouse lower than the desktop to encourage healthier posture and reduce wrist and shoulder strain during long sessions.
• Built-in back baffle: A rear stop prevents the keyboard from sliding off the tray during use, keeping devices secure on the platform.

Who It's For

This tray is ideal for people who use a full-size keyboard and want to clear desktop clutter without permanent installation; remote workers, students with limited desk space, and casual to mid-level gamers will appreciate the wide surface and sturdy clamps. The ease of assembly and included hardware make it a good fit for those who prefer a tool-free or low-tool setup.

It is not appropriate for desks with curved, beveled, or rounded undersides or any desktop that has crossbars or support beams underneath, because the clamp system requires a completely flat, unobstructed underside. If your desk does not meet the 31.5 in minimum width requirement or has non-flat edges, look for a tray designed for those frames or a screw-mounted option.
