I have a TiLite chair, an AeroX. At this point it is a backup for me and I have only really used it once. However, when I was shopping I compared it to an Invacare chair and preferred the Ti product. In the case of chairs, that is all that TiLite does. My chair is attractive, extremely light, well balanced and well made. The rep I worked with made a huge difference in getting exactly what I needed, but it meant I had to pay full price. Honestly, his expertise was worth it because there are so many little details to be considered in order to get a chair that fits you and how you want to use it. The chair is probably only about 22 pounds and would be lighter if I had a fixed front end instead of the swing away option.
As far as what others think, my philosophy is that if people are bothered then that is their problem. I've found that most people are helpful and kind. (Maybe because I am female, who knows?) I think it is more important for us to get out and be seen, even with our disabilities, rather than let ourselves be swept under the rug. Everyone has some kind of disability. Ours are just more noticeable. Get out there and do things and don't let anyone hold you back!
