Remember those weird chairs they had in the 80's, they were supposed to be good for your back? There was a slab for your butt that slanted towards the floor, and another slanted slab for your knees? I liked the slant, it DID feel good on my back and I sat up straight, but I didn't like the weight on my knees after a few hours. I HATE those adirondack chairs for that reason- they're slanted wrong and are too hard to get out of.
