OMG this is GREAT!
I am a 285 lb male  at 5'9&#34;, and I have a real problem driving more than 3 hours due to back pain. This is like riding on a cloud! Not only VERY comfortable, but it is not hot like foam cushions (or regular car seats) can become!  It is just the right size, but leaves you little room if you don't sit on it squarely. I can see people who have larger back-sides finding it too small, but, as I said, I am 285 lb at 5'9&#34;.<br /><br />I can see people who weigh 350+ may not get as much comfort as others, due to their weight. They may want two.
