I purchased these stools for my children to use at their desks.  They have had no difficulty maneuvering them over the linoleum floors, despite other purchasers' experiences.  My children are of normal height and weight and are able to sit comfortably and complete tasks.  I have even used the stools for working at my computer.  In my efforts to allow them some independence, I allowed two of my children to assemble one stool each.  I had to go back and tighten the bolts, as they did not secure them snugly and two bolts fell out after several days of use...no problems since.  Just be sure to situate the frame so that the handle to adjust the stool height sits on the side, and not between the user's legs....awkward! :)
