Thank you Jeannie. I guess I should go to the store as, other than weight, I don't comprehend the features, the pros and cons of each feature like different cushions, foot rests and so forth. I am looking for something easy to lift and store in car, safe to operate and easy to operate. I'm guess I should just look and learn!
