My favorite listening chair is a three cushion Flex Steel sofa. Just the right amount of comfort - not too firm and not too soft. The back hits just above the top of my shoulders. With a padded ottoman, the center cushion makes a comfy place to listen for extended periods, plus enough room on the sofa to share listening with the wife or a friend.
Sometimes, during late night listening, when I get tired, it's nice to be able to curl up on a comfy sofa and crash for awhile and let the music play on.
