the Ekones Stressless is an excellent chair for lounging. i use one for TV watching, have owned 3 or 4 over time, and really like it when i have the back reclined. but for listening to stereo it’s not ideal, in that mostly it cups the sound around your head, and it does place the weight on your tailbone when your head is at the tweeter height. so it’s a 2 hour chair for serious listening.
there are Ekones Stressless chairs with lower back rests that don’t cup the sound, but the tailbone issue remains. so it’s compromised.
OTOH a perfect chair/zero gravity chair from the relax the back store, with a fixed back and thigh support and a weight transfer for your lower legs unweights your tailbone, so you can sit in it indefinitely. some ’perfect’ chairs have issues with also cupping the sound, but my perfect chair has a narrow back rest and head pillow and so reflects sound away from your ears so no tonal shift.
i’ve owned my ’perfect chair’ since 1999, 24 years now. i can and do listen for 12 straight hours with it. i’ll be buried with it.
