Theoretically, a high-backed chair puts the back in play as a reflective surface that will adversely affect sound. The reflections will cause all kinds of cancellations and reinforcement of different frequencies, and so, it is best to use something with a low back.
In reality, I personally like my high-backed reclinging chair, which is similar to the Ekornes chair. I have no problem with the sonic effect of using that chair -- the sound actually seems more focused when I use that chair.
