Situation: I am standing by the keyboard on my right facing a chair in front of me within reach.
Alternative situations: Both my hands are holding the back rest of the chair, the table is to the right and bag is also on the same desk. I am facing the backrest of the brown chair in front of me with both my hands on the backrest as I perform an assisted squat exercise, the keyboard is to my right side.
Question: How many wheels does the chair in front of me have?
