Ladder is a useful tool for people to maintain their environment. However, traditional ladders do not provide extra places for temporally hold. It's inconvenient for people climbing up and down to put whatever they just changed and get other tools they needed. Thus, Ladder Helper, proposes holders on the steps and allows the users to put tools or stuffs during repairing processes. With the Ladder Helper, the users can repair their living space more effectively.
