Each cushion is stuffed with a firm foam padding that has been stacked in layers, this will help with the support it is intended to give.
Moving to the top of the board, there are two cable holes, one on each side, to provide access to the USB 3.0 hub on the inside.
One of the four USB ports are directly accessible from the top, providing easy access should you wish to use a removable storage device or for another reason.
The underside of the board reveals that it is made from a firm plastic, and there are two sections that can be removed with the aid of a screw driver.
Opened up you will find that there is a huge space suitable for storing cables, as well as providing access to two USB 3.0 ports which could be used for a USB passthrough on the keyboard, or in any other way you see fit.
The smaller compartment features the USB 3.0 type B port for the connector and an additional standard USB 3.0 port.
As visualised, you can use the internal supports to aid in cable management, but the amount of space available will allow you a fair amount of freedom in regards to how tidy one needs to be.
The Support board all setup with a mouse and keyboard set, the ROCCAT SUORA FX looks tiny compared to the space provided and there is plenty of space for much larger keyboards.
