somewhat stupid question re: sliding glass doors

[Slow Play Ray]

i tried google and got sick of wading through crap. everything i could find is only answering half my question, so i am turning to the OOT collective.

i bought new furniture the other day, but i think the couch may not fit through any of my doors. i say i think they may not because i won't actually own the house for another week, so can't get in to measure. but i would like to know now what i may be getting into. anyway, the place does have a sliding glass door. so my question is, if it becomes necessary, will i be able to remove both the sliding and stationary portions of the door to get the couch in, and then safely replace them?

thanks in advance for any advice.
