1. A household appliance, comprising:
a support for goods arranged inside the household appliance, and
an arrangement for extracting and retracting the support out from and into the household appliance,
wherein the extracting and retracting arrangement comprises:
first and second rail units extending substantially along and in parallel with each other, wherein the first and second rail units are arranged to be moveable in a longitudinal direction in relation to each other; and
first and second sets of roller elements distributed longitudinally between the first and second rail units along first and second opposite outer surfaces of the first rail unit so as to facilitate said relative movement,
wherein the first rail unit, at least along one or more segments of its length, is provided with supporting material in a region that extends between and is located intermediate to the first and second opposite outer surfaces so as to allow for absorption of compression forces in the supporting material and resistance of compression deformation of the first rail unit when one or more of the roller elements exerts a force onto any of the outer surfaces,
wherein the first and second sets of roller elements are arranged between the first and second opposite outer surfaces of the first rail unit and corresponding opposite first and second inner surfaces of the second rail unit,
wherein the second rail unit comprises an outer frame made of a metallic material and a rail insert made of a plastic or polymeric material, wherein the rail insert is arranged inside and is fixed to the outer frame, and
