hips above knees, knees below hips…tomato tomatoe 
over the weekend i took a 1-1/2" piece of PVC pipe and cut it to about a 10" section and just bungee-corded it around my desk chair with the lumbar pad in front of it to give it extra support…so far it feels great.
Cost: Nothing

5.) I have 2 lumbar supports; but neither keep their shape for long…thinking of buying a 1-2" dia PVC tube to insert inside one of these “support” devices[/quote]
OK, I’m looking at the same back pillow I’ve used since 1995, no exaggeration. It is the Back-Huggar by Bodyline Comfort Systems. I keep one in my car and one stays with my desktop at the apt.
Needless to say, I highly recommend this particular product:
i have one that is just like that, depends what is on the inside (just like with women! lol) but this one i have sucks…i sit against it and it flattens. maybe i should cut.

I wonder if the brand actually does matter in this case.
Good point though, I’ve never been much higher than 215lbs yet so that could be part of your problem.
