Crespo says about the AP-231 Air-Deluxe
A very comfortable footrest. This footrest can be used separately from the chair and can therefore be placed at the desired distance, depending on the length of one's legs. The footrest can also be used to sit on. Fitted with a very comfortable padded 3D fabric. The comfortable filling of this fabric is highly breathable and does not retain moisture. In addition, the footrest is ergonomically shaped and provided with a very stable frame. After use, the footrest can be easily folded into a flat and compact unit.
