The measurement of 11. This stand does not fold- it works well the way I use, but I don’t think it would travel well. Looks sturdy enough, and specially helped me saving a lot of space in my room. I personally dont care though, its a slight roll that doesnt make me fear for safety. I returned the email asking for an Account Specialist to call me. non hanno "noise canceling", larchetto può essere scomodo a chi porta gli occhiali, e la custodia di ricarica è un po ingombrante. Very useful and works as described. Love this brand of slippers! The shoes from Clarks are what I expected and I am happy with the comfort Ive had this exact unit at the office for 3 years.
