I have now seen and tried out in several furniture stores the stool. It is available in several variants (sometimes with armrests, sometimes with chrome feet, ..). I have decided after a long time for this variation and do not regret the purchase. The structure can be realized very easy and without any tools. The armrests can also be in the width change, ie you can adjust the distance between the armrests. However, only with Imbusschraubenzieher, which is however included. Why the manufacturer has installed a stupid eiriges wheel for height adjustment, me remains a mystery. It should be out looking for the right armrest height once more and no longer change. Otherwise super :) Fast Delivery!
