Yeah loads of people just sit around in VR. Seen the full body guys in VRC? They manage just lying down, let alone seated. 
Quest 2 is the most cost effective way in. Pretty cheap, but you pay in getting ZUCCED since you need a facebook account and to tie it to that so they can watch you hug your friend. You can play PC VR with it using a cable or over good wifi connections.
Non zucced options are pretty sparse at the low end since zuccsets OWN the low end so hard there's no market until you hit enthusiast.
