The stairs installation (10) has at least two tread steps (12) and at least one set step (14), all joined together in one piece, the set step being positioned between the two tread steps. The two types of steps act as supporting components for the stairs installation. Theey can be made of concrete and/or natural stone and/or wound and/or glass and/or plastic. Two tread steps are connected by at least one fixture unit, which is insertable in the set step between them, through a through hole. Between the set step and at least one tread step is an elastic material, particularly neoprene. |
