Yes You'll be able to fit a full size mattress in the rear of a Subaru Outback but in order to do so You're going to need to fold down the rear seats. They will have a latch You're going to need to pull from the rear of the vehicle. Once down the mattress will fit just fine but You'll be limited to driving with just YourseLFAnd one passenger. You won't be able to fit anything bigger than this like a queen sized mattress.
