As long as it's not *too* comfy. The armchair I park myself in (to veg out in in front of the telly) suffered a broken spring, and it's now treacherously deep; visitors have to be warned that it's difficult to escape its embrace.
People always seem to get it wrong about soft chairs and beds; possibly it's a race memory from when His Lordship was the only one who could afford deeply-stuffed matresses.* Research shows that a soft chair increases reported comfort levels, but also increases observed rates of fidgeting. Nowadays we pay extra for deep-stuffed matresses, then pay extra again for orthopedic ones.† *The* most comfortable beds I've ever slept in have been simple standard Uni-issue ones: a four-inch Dunlopillo matress over plywood slats.

† No, I don't just mean gravel, or the earth of one's homeland.
