Yes infinite screaming is on here
Your new sofa is sactional, so it can stack in a small area
Old sofas can be tilted up on end to be out of the way
If the snow doesn't stop them 1-800-Got Junk will carry the old sofas out and away for a fee
A flattened Amazon Box, in a pinch, makes a nice doormat to sop up slush from shoes
Anything else?
Stand the sofas up in the middle of the room, put the sactional boxes in the middle of the room.
Lovesac is like lego, so until you try to make it sofalike its smaller.
I've only seen a lovesac in the commercials, and they show people easily moving the parts around.
YT confirms what I thought, each piece is in its own shipping box, so shouldn't be 200 lbs in 1 huge box.

I think you can handle the pieces.
I will also note that a cup of cocoa or coffee on a cold day might encourage the fed ex guy to move the extra 15 feet to put the boxes in the garage for you.
