sitting properly

Body: 

I admire Kristine that she can sit for hrs either on her heels or crosslegged.
I have quite bad arthritis in both knees and those postures just don't work for me.
Can someone direct me as to what is the best posture, pelvic wise for sitting on a chair or couch?

Hi doglovertoronto,
Generally speaking, not many chairs or couches are designed to facilitate us sitting in anything resembling supportive posture. Most allow us to slump backwards, losing the lumbar curve and sitting more on our sacrum than our sitting bones.
Can you invest in one of those exercise balls? Those are fantastic for posture, there is no way to slump on them, and your knees should benefit as well. If you must sit on a chair or couch, arrange pillows and firm support to help keep you in posture. It takes some ingenuity but it is possible (I love the hot water bottle in my car, I can keep it filled with just the amount of water to perfectly support my lumbar curve while driving).
Good luck ;)

Thanks so much for all the good advice.I will look into an exercise ball
In the car I was able to bring the seat right up straight so I don't slouch back but at home, the couch , like all the couches have that downward motion.

Also try a low, wide stool. I have an old-timey milking stool that I use on occasion. Any kind of seating can work if you are toward the front of the seat, pulled up in posture and relying on your own spine to keep you there. After a while, you will feel quite comfy even without using the seat back. :-)

I often sit on the forward edge of the couch--that helps. then i don't worry about slumping back. also good wood chairs work.
if i want to relax, i lie down on the couch and spread out. if i feel bad i even do that at people's houses. no one seems to mind--but then i do have fabulous friends ;-)

I use the pedestal off an old office chair with a piece of horizontal plywood on the top and an old sofa cushion on the top, as an office chair. At social functions I prefer a dining type chair, but a foot stool or rock wall works just fine. You can forget squishy sofas and armchairs. Perching on the edge is the only way to use them, unless you do Kiki's trick of reclining in Renaissance splendour, dripping in velvet and diamonds. Dream on!

I was in an ergonomics shop the other day, buying a split keyboard (to sort out my dicky wrist), and spied a saddle stool. It is a gas lift job and it has a big fat, adjustable, padded saddle seat. See http://www.ergolink.com.au/proddetail.php?prod=SSSAYA&cat=38

Has anyone used a stool like this?

I can really feel the difference when I sit on our soft couch. We have a plain hard wood rocking chair that I sit in now instead of the couch. My problem is at work. The office chair is just not good! I will try a hot water bottle in the car, too. Do the exercise balls really work for sitting?

that is one cool stool!
I love it.
I have no idea if it would be comfy but I know it would be worth a try if I had to sit all day.

I love it, too...looks divine...
