Key Features to Consider When Buying A Keyboard Tray

Every under-desk keyboard tray will give you a different feature, it is important to understand which tray suits your needs and integrates seamlessly into your workstation.

Although keyboard trays consist of a few simple parts, you need to look at the track bracket that will mount to your desk and its adjustability to choose the ideal platform to rest your keyboard on. By carefully looking at the individual aspects of each design, you will be able to make your best selection.


Having a keyboard tray that integrates well into your existing work is a very important requirement while buying under-desk keyboard trays. You do not want to get trays that stick out of your desk and make mobility difficult for you. While this may solve your basic requirement, it can cause a great hindrance to the overall workflow at your desk.

Ideally, you want to choose a keyboard tray that adapts well to your desk and fulfills the space you need for peripherals. Trays with separate extensions for mouse pads can be a welcome benefit for some as well. There is also the possibility of purchasing a separate mouse tray.


With under-desk keyboard trays it is important to consider how you will attach the tray to your desk. You can either choose a design that needs to be drilled into the table or can be clamped to the sides.

If your workspace is a temporary arrangement or you do not want to drill holes then we would suggest getting a clamp on keyboard tray. Whatever your choice, you have plenty of different options to choose from.


Keyboard desk trays need to be adjustable enough to fulfill your needs properly. This includes being able to modify the amount of clearance the keyboard tray offers. Another additional feature to look at while buying keyboard desk trays is the tilting angle so that you can adjust the angle of the keyboard tray as well. These customizations allow keyboard trays to provide a wider range of sitting and standing postures.

An important feature on under-desk keyboard trays is retractability, this can greatly ease movement and make it easy for you to make your workspace more accessible at times. However, one of the most important things to consider when purchasing under-desk keyboard trays is the amount of clearance and leg-space you will have after installation. It is recommended to measure your under-desk space so that you can make a better decision and are satisfied with the amount of leg-space available to you afterwards.


Keyboard trays need to be durable and last as long as possible. In case there is an unexpected issue with your keyboard tray, you will want a warranty to help safeguard your little investment. Therefore, consider the different types of warranties available that can range all the way from six-months to life-time warranties.
