Acoustics and chair

No leather, it really is that simple. The reflection above the head area is also, right on. Stressless does offer, on special order, fabric. A lot of people have the Eames/Knoll classic chair but it suffers from leather, tilt angle and head reflection. However, it has high partner acceptance, but so overpriced. All considerations should keep the head area open, it is the most important. The sound needs to pass your ears, like the wind. As for the leather, well your beefy body will cover most of it, so don't put on your leather chaps, vest, etc. Cupholder? Well you can't have everything.

Get the Stressless chait aready mentioned and make sure the back does not go up to your ears. awesome chair and no worries about leather as your body cover about 90% of the chair so the soft leather is a non-issue with reflection.

Just don't wear your leather pants and jacket while listening.

Most important acoustically is no headrest. I had a comfy leather recliner with a high headrest which looked nice. When I changed it out for a low back chair, the sonic difference was noticeably better. I don't recall ever resting my head on the headrest anyway so no loss there.
This has been discussed many times so a check of the archives might prove useful. Or we can just do it again.

Levitation is the best solution.

I am surprised by how many dealers have those tall-back Ikea chairs that go above ear level. They always ask me why I don't sit down, but the tall back completely changes the sound. How do they not know this?
