Yup...sorta! I have two Brute Lites...(they're for heaver people) more room..I have one old one, maybe 10 yrs old and a new adjustable model. They are both the finest you could ask for, in all regards..lite weight, probably the lightest you can buy, at least the lightest and the strongest....they don't shift or squeak, and they are solid! I modified mine with padded straps, but you can get by with what they come with...other than that, they serve me well for nigh on ten years, with no need of repair....
I would get the Baby lite that you are interested in, but I weigh about 220, and they wouldn't fit right about the belly...you need enough room to be comfortable..and these are comfortable...I can sit relaxed all day and feel great!
If you're small, go for the Lite, if in doubt, call the manufacturer and ask him, he's a small businessman who's interested in feedback and will help you out.
