The larger the sliding surface, the more the pressure exerted on it will be distributed. The smaller glide foot with a diameter of 28 mm – or 29 mm in the case of the Fixxclick and Footfixx Hollow 3.0 – is often considered more aesthetically pleasing for slim chair legs. However, the larger glide foot with a diameter of 34 mm – or 35 mm in the case of the Fixxclick and Footfixx Hollow 3.0 – allows your chairs to glide more easily. For this reason, we generally recommend using the larger glide foot for rough floors, intensive sliding and/or heavy chairs.
