If you plan to use a desktop computer that has a CPU and you are looking to save space, you should strongly consider adding the Standee Flex CPU shelf to your Standee Flex desk. The CPU shelf attaches to the frame and moves up and down as you raise and lower the frame. By enabling your CPU to move with the desk, you eliminate the risk of your computer cables getting stretched, damaged or disconnected. The CPU shelf is made of steel and is height- and width adjustable to fit different CPU sizes. It also features an easy-access pull-out slide mechanism. If you are a laptop user, then there is no need to add the CPU shelf.
