With the quest release coming, having a rec room like seated mode would allow for people who cannot stand for extended periods of time or for people who are tired and want to play a few rounds seated to play more.
I do know it is possible to increase your height normally, but that would require changing of boundaries and you can't really consistently get the same height by doing that so that would not be good.
This could be in the form of a setting, or just an automatic toggle if your height drops below a certain point, either way any implementation of this would be great.
