I feel that the chairs are integral to the listening experience, and that people who are building listening rooms have to take their seating selection seriously. One will spend at least forty five minutes without moving sitting in this chair, and perhaps longer, given a remote control system. This is one room-aspect that can no longer be ignored.
Also worth noting: a La-Z-Boy or similar chair is such a bad idea for listening. Lean back in it, and your ears will lose the openness of a quality listening experience. Being surrounded by chair padding is not the same as listening in a "dead" room -- it's not even close.
If I'm in the market for a chair, what do I do?
Here are the basic rules from websites and books oriented towards beginning listeners: Chair Back no higher than just below the ears. That's it. That's all they give you. Do they want us to thrift-shop for our chairs?
Aspects of the Perfect Chair
I've always taken seating seriously, and most of my time selecting chairs has been for my computer desk. This hasn't been a bad thing: when in college, I spent a lot of my life in the same chair. I was glad I spent extra on it.
We can use those desk-chair concepts. What is important for a task chair? Ergonomics: sitting for long periods of time isn't bad for you. Comfort: sitting for long periods of time doesn't hurt. Mobility: you almost NEVER want a chair in the middle of the room ALL THE TIME, so the chair needs to be easy enough to move to and from your desk. This is high fidelity audio, so price isn't a factor, of course. :-)
We will add back height, since it is apparently such an issue in audio circles. And yes, it matters. Try sitting in a bowl chair and listening to some nice speakers. Your music will be as cushioned and floppy as the chair.
What does everyone else talk about?
Some folks online mention Barco Loungers, which sound like the most luxurious and overdone idea. Other folks recommend very large beanbags, and why not? They'll keep you supported and well-cushioned and mold to your shape. (Mobility is out of the picture, and size is an issue, too.) Stressless chairs, Ekornes chairs, both popular because of the comfort.
What else could I use?
Using our task-chair metric above, we could use an Aeron chair. (If you ever sit in an Aeron chair for more than a few minutes, you'll forget you're sitting. THIS is what a listening room needs!) Any nice executive task chairs with backs that support up to your shoulders are a good idea; for a long time, I had a $300 chair at Staples picked out as my dream chair. Anything like this can work, and since they almost all have wheels, mobility is a big plus. My office chair (in which I sometimes spend 3-4 hours at a time) is ideal.
Alas! The most disappointing thing is the price of a truly perfect chair. My best task chairs have cost me over $100, and I would consider those marginal listening-chair choices. If you think that's a lot, don't bother looking up an Aeron, Barco Lounger, or even any of those big fancy beanbags.
Work on finding an office chair or something designed for lounging within your budget. If you can, go to the store to test it out. Sit there for twenty or thirty minutes -- I'm not kidding. Don't get up unless the associate asks you to move. You need to test long-term butt strain, and thirty seconds won't do anything. (By the way, I've sat in Staples, Ikea, CompUSA, and other stores for thirty to forty-five minutes at a time. No one has ever asked me to leave.)
What did the AUTHOR do?
I think I've settled on a less-than-perfect option: the Ikea Poang chair. They are infinitely comfortable: I absolutely love these chairs. They are featherweights, so they're easy to push aside. Yes, the back is a little high. Yes, the chair sits a little low. The price is perfect, however, for what I'm looking for. I pride myself on my hi-fi audio system being a "budget luxury;" this chair embodies that concept. The padding isn't overthick, so it shouldn't kill my listening environment. Everyone should go to their nearest Ikea and sit in one of these. Try it. You'll like it.
(Edit: apparently, these are popular for listening rooms in dealer showrooms, probably for the mobility and comfort thing.)
As for the ultimate decision, find something especially comfortable, ergonomic, without a headrest. You'll be on the right track. Then let me know what you have. We could start a movement:
CARE ABOUT YOUR CHAIR!
