Much has been written in this forum about the proper posture people should assume when one is supposed to kneel in a church building with no kneelers.
I have never heard any discussion as to what people ought to do if there are no seats and it is a time of the Mass where sitting is the proper posture.
Should/must one stand? Is it possible to bring one’s own chair? Is it permitted to sit on the floor? (I have a hard time imagining most people would want to do so but…)
I’m sure we’ve all seen plenty of people standing in the narthex of the Church (for all kinds of reasons.) I have often seen ushers bring chairs to people who are out there because they have young children or because the Church is very crowded. But I am really wondering about church setups (say a historic church)? where there simply aren’t ANY furnishings provided.
