Under Desk Keyboard Tray Clamp On with Wrist Rest and Arm Support, 90 Degree Foldable Mouse Tray

Keyboard Tray Under‑Desk Ergonomic Extender A practical solution for creating a comfortable, organized workspace at any desk. This clamp‑on tray adds a dedicated surface for a keyboard and a 90° foldable mouse platform, while the built‑in forearm support and wrist rest keep arms in a natural position. **Key Benefits** **Improved posture**: The tray positions the keyboard at elbow height and the mouse at a right angle, reducing the need to reach forward. The forearm pad and wrist rest keep the arms and wrists aligned, helping to prevent fatigue during long sessions. **Space‑saving design**: The mouse platform folds flat against the keyboard surface when not in use, keeping the work area clear. **Easy, tool‑ installation**: A sturdy clamp attaches to the desk edge and slides to the desired position. No drilling or permanent modifications are required. **Adjustable fit**: The clamp slides to accommodate desk thicknesses from 0.8 inches to 2.5 inches, making it compatible with most standard desks. **Durable construction**: Made from reinforced steel and a powder‑coated finish, the tray supports a total load of up to 30 pounds. The non‑slip surface keeps the keyboard steady. **Product Features** Keyboard platform dimensions: 22 inches wide by 8 inches deep. Foldable mouse tray dimensions: 10 inches wide by 7 inches deep. Integrated forearm support pad with a soft, non‑abrasive surface. Separate wrist‑rest shelf that can be positioned on either side of the keyboard platform. Clamp made of ‑strength steel with a rubberized grip to protect the desk edge. **Typical Use Scenarios** 1. **Home office workstation** – Install the tray under a compact desk to create a full‑size typing area without sacrificing legroom. The forearm pad and wrist rest make it comfortable for extended writing or video‑conference sessions. 2. **Gaming or design station** – The 90° mouse platform provides mouse angle for precise control, while the fold‑away feature keeps the desk clear when switching to other tasks. The sturdy construction holds heavy mechanical keyboards and gaming mice without wobble. 3. **Shared or hot‑desking environment** – Because the unit clamps on and releases without tools, it can be quickly moved between desks. The adjustable clamp fits a wide range of desk thicknesses, allowing each user to set up an ergonomic station in seconds. **Why It Stands Out** Combines keyboard tray, mouse platform, forearm pad, and wrist rest in a single, compact unit. Foldable mouse tray reduces clutter when the mouse is not in use. No permanent modifications; the clamp system preserves the original desk surface. **Installation Summary** 1. Open the clamp and place it over the desk edge. 2. Slide the clamp to the desired position and tighten the screw until the tray is secure. 3. Adjust the mouse tray angle, position the forearm pad, and place the wrist‑rest shelf where it feels most comfortable. This under‑desk ergonomic extender offers a simple, versatile way to upgrade any workstation, supporting better posture and a more efficient layout.
