Chair

Increased area of contact and weight distribution for everything aft of butt...i.e., ottoman or something else for resting entire length of legs and thighs at a slightly elevated height than butt (spread the weight)...

I’m forced to cut my listening sessions short due to lower back pain (chronic, result of an old injury)

I’m using a Stressless Max.  Very comfortable recliner but what I like most is that the back and seat can be adjusted separately. So if I’m doing some serious listening, I can leave the seat parallel to the floor and lower the back so it’s not right behind my head and therefore won’t impact the sound.

I have this nice black leather recliner i had bought for my mother over 15 years ago. from Macys.It was a,present and it has,held up very well and thats my relaxing, music chair.

I have sat in authentic and replica Eames chairs and find them uncomfortable, and I really don't like the style. I have owned Ekornes Stressless recliners and they are extremely comfortable, but that headrest definitely negatively affects SQ. I currently use a plain Jane rocking chair, and love it. It's comfortable, but not "fall asleep in it" level.

I've had 6 back surgeries, the last one a 12 hour marathon.

The best thing is to get up often. I seldom sit for more than 30 minutes at a time.
