I selected this walker because it is very plain and has only two wheels instead of four for stability. No brakes are required and it is fairly light in weight. My Mother needs a walker with a seat, but her eyesight and strength level make it difficult to set or release brakes. With this model she can just turn and sit, which is all we need. The adjustable hight level is set by pressure and doesn't lock with a pin as I expected. The walker was delivered in a week.
