The armrest is a great feature to have on any stool. Armrests give added support, allowing you to take the weight off your shoulders, making the whole seating experience all the more relaxing. Armrests also offer added security, especially for younger children, by creating a barrier that stops you from falling off the sides of the seat should you lean too far or, as in the case of children, be a bit too boisterous! It is important to remember, however, that adding armrests to a stool increases the overall width, and can also cause a slight obstruction should you wish to store the stool under a counter or tabletop.
