Will a approx. 7 foot long couch fit into a Honda Odyssey, with both
 

passengers seats down? Don't tell me to measure it, I know that....I don't have the ability to measure the trunk space in the Honda right now.

A couch that is overall outside dimension 7ft. will fit in an Odyssey. So it all depends on how much approximating you've been doing. Get a ruler.It also depends on the other dimensions. That is; how tall is your couch and how deep it is from front to back.
