To help you choose the suitable model for you, we want to give you some general guidelines depending on how you want to use Walkstool and depending on your height and weight. The most notable differences between WS Comfort compared to WS Basic is the bigger seat sizes of mesh material and the bigger rubber feet which reduce risk of sinking down when being out in the forest and on wet grass. Please bear in mind that a chair you use in kitchen and dining rooms normally have a sitting height of 45 cm/18in.
