Could someone (anyone) explain any secrets they may be aware of for getting a sofa that is measured as 37" High x 44" Deep x 90" Wide through a standard size 36" Wide x ??" High doorway?

Also realize the legs are probably 3" of the overall height but not sure whether they are removable and there is also a pair (front & back) in the middle.

Physics says it can not be done; but that what they said about 'dark matter and dark energy'.
