 Stairs are the product of modern culture because stairs are indispensable construction in both great mansions and lower buildings of two or several stories. Stairs are main passages for reaching every floor, thus they undoubtedly provide great convenience. Stairs are practical and, however, are also places that are most possible to cause injured for people, especially for children. There are may stair safety mat in the market, however, most of them are provided for normal adult instead of 14 year-old children.
 Traditionally, the stair safety mat is provided for skidproof, stop falling over the stairs, noise muffled, or secure from the edge of stairsteps. Take the examples of stop falling over the stairs and noise muffled, which are not suitable for children who are learning walk, because the children are under 10 kg or so, they almost can't make noise by crawling over the stairs comparing with the weight of a normal adult which may be 60 or 70 kg even more than 100 kg. And children, for example, usually don't having enough grabbing power at the handrails when falling down over the stairs, which may result in injured with the good-for-nothing typical mat. For a normal adult, it is very easy to grab something, such as the handrail, and to lower the center of the gravity for stopping falling down; therefore, the stairs having the function of stop falling is not suitable for everyone.
 Besides, there is another kind of stair safety mat having upward protrudent portion at the edge of each stairstep for stopping falling down over the stairs and preventing dashing. This may be useful for adult, however, which is not suitable for walk-learning baby, since there is different height between the upward protrudent portion and the inner-side stairstep. It is not convenient for children, especially for the walk-learning baby, because the children is walking unsteady even on the flat floor when learning walk not to say the different height stairs.
 Furthermore, there is a limpness crashproof with 90 degree covering the edge of stairsteps for protection. However, no matter what kind of material the traditional crashproof may use, it may reduce the injured and cause painful when falling down on the edge of stairsteps because of the reflection power. The mat in the market is only provided for stairsteps and ignored the last stop, floor, and thus it may cause injured when falling. It should not only provide mat for stairsteps, but for the floor adjacent to the stair.
 For the sake of that the mat fixes on the stairs, mostly it uses drilling fix, which may cost a lot of money and time to fix. Besides, some use strong viscose to fix, which has the disadvantage of dissemble.
