Just imagine if one has to climb over a 15 storey building. It would be very difficult for him. He would be totally exhausted after climbing to the 15th storey. So to remove this problem and to have some comfort level, there is stair lift available in the market. These lifts can take one to any storey building without any hardwok done. One just have to press a button and the lift automatically takes one to the desired floor.So it has helped a lot in removing fatigue of a person.
