This little bird, beside just looking cute, it also a big help. The bird, called the Companion Bird goes on top of railings and helps the elderly or less mobile people to climb the stairs. It was designed by Kim Bo-kyung & Baek Eun-ha.
I’m not really sure how helpful the bird would be but I think it might be useful for people who have a hard time gripping things (perhaps due to arthritis). The bird would enable people to climb the stairs without having to readjust their grip- they could grip the bird once and slide it along with them all the way up the stairs. Plus it adds a pop of color and visual interesting to the handrail. Good idea.
