That's a very nice looking chair.
The professional approach is to use a microphone to measure where you are having reflections and at what frequency, then install the appropriate material in the appropriate place to mitigate it. You might ask what reflections do you actually have that need fixing before spending on this. Putting panels around randomly may not help, or could even make it sound weird, unless the room really echos a lot.
Having a measurement microphone is good anyway, since you can calibrate the frequency response and phase much more easily.
In a room that rings obviously, just installing any sort of absorbent material anywhere can really help. Your comfy chair probably makes a difference.
The first recommendation usually is to put a thick rug on the floor if you don't have a carpet, but you sit so close that you may not be having an issue with that. It's also common to put some foam in the corners where the speakers are so they aren't instantly making reflections off the wall. Reflections that arrive later than the direct radiation from the speaker are actually less important than the ones that come together at the same time, so that corner is important.
In general, sitting close to your speakers does a lot to mitigate acoustic problems in a room, and it's one of the reasons people think studio monitors sound so good. Some of those speakers really are exceptional, but they have the advantage of being used close-up, and having less distortion because they just don't have to play as loud compared to if you sat meters away.
