How to move a sofa with a length of 208 and a width of 80 out of a door with a width of 73 and a hei

After drawing and analyzing, the straight edge of the sofa is longer than the beveled edge of the door, if you can't get out horizontally, either dismantle the sofa, or consult the sofa seller, they should often deal with this kind of thing.

If you can't get in the door, you have to enter through the window and hang it with a rope.

I only know the length and width of the sofa, but I don't know the height (the height of the back of the sofa), and I don't know what objects are blocking the side of the door, and what the angle is (you can try to move away), first, if the height of the back of the sofa is less than the width of the door, try to pass obliquely and sideways: the side of the sofa width 80 is parallel to the side of the door height 183 or at a certain angle (when less than 45 degrees), and the long side is perpendicular to the door or less than a certain angle, you can enter; Second, if the height of the backrest is equal to the width of the sofa 80 is greater than the width of the door 73 (this is the limit of design and aesthetics), then put it down to the side, the least side of the sofa H (thickness), according to the principle of vertical isosceles triangle and the Pythagorean theorem, calculate that H is, it is far less than the width of the door, as long as the inverted and inclined angle is appropriate, it will definitely be able to enter. (Unless there's something behind your door to block it) as shown below

You can try using the triangular method to see if you can come out...

Wondering how you moved in.

Move out as you move in! It is estimated to be disassembled!

Is the sofa height 73, if not, you can go out with a turn.
