By far this is the most versatile chair I have ever owned. To begin with the front wheels are tucked further under the seat than most other chairs. This allows for my pant cuffs NOT to be rolled over & cause me to come to a screeching halt. Also, when the brakes are locked, the chair will not move. This comes in handy when I am placing my feet on something to tie my shoes.. The chair does not roll away. The only downside I can see is that the wheels are not covered by rubber tires. This does not provide for 100% traction when traveling over uneven ground.
