Answer: 
To extend the Walkstool legs slowly pull the legs down until the red safety button is visible and locks into position. Once the three legs are locked into place the Walkstool is ready to be sat upon. As with any three-legged stool the proper way to sit on the Walkstool is with one of the three seat points between your legs (like sitting on a bicycle seat). To retract the Walkstool's legs push in the red safety button, while pushing the walkstool's legs back towards the seat. Please do not attempt to stand on the Walkstool, due to its three legged design it is not safe to stand on the Walkstool. As for maintenance, Walkstools never require oil or lubricants; they are designed to work dry. If your Walkstool gets extremely dirty, you can remove the legs and wipe them down with a clean dry cloth. The legs can be removed by pushing the red safety button and pulling out the legs, after the legs are in the extended position.
