Ah, Volvo seats from the 80s!! They were considered 'perfect sitters' by many around here!! Hah! (Almost) been there, done that!!
Chairs vs sofas - big difference between those.
Chairs - my best task seater is the HM Aeron - mine is approaching 25yrs old, and still works nearly like new.
Best comfy chair has been a LazyBoy recliner - leather, and huge....problem is, I can never manage to stay
awake in the silly thing....but will likely be the one that's left for me at the End of Days, after I've been forced to sell off all the Good Stuff:>
Dining room, also Eames shell style (I also still have 4 of my parents orginal fiberglass (blue!) ones from the 50s...darned near indestructable!) are surprisingly comfy.
Sofas - much bigger aesthetic impact, not to mention audio.
I like the 'spindly' looking Eames designs, but the Stickley stuff isn't bad (less good for audio) either.
Big, overstuffed, and soft...no thanks; my back is bad enough without having to try to get in and out of one of those things!!
You pays yer money and takes yer cherce.....
