I have a Trane furnace.

One of the heat registers in my livingroom is underneath my sofa.
There are two registers in that room.

Is it safe to completely close off the register, or would it be better
to leave it open a tad?

I am not sure if this could damage my unit, and thought I would get some
expert advice here.

Many thanks.
