Abstract:
An adjustable stair riser includes a body portion made of a flexible material. An upper connecting portion is disposed adjacent to an upper end of the body portion. A lower connecting portion is disposed adjacent to a lower end of the body portion. A front surface of the body portion is concavely shaped between the upper and lower ends so as to create slack for moving the upper and lower ends toward or away from each other to accommodate spacing between adjacent treads of a stairway during installation. The concavely shaped front surface of the body portion additionally provides an obstruction free path of foot travel.
