Driver's and passenger seats only. The back has a sleeping platform that fits a full-sized futon pad. Two people can fit relatively comfortably. There is space on the platform and underneath for storage. This is a dog-friendly rental and I use my Honda for hiking and camping with my dogs. So, there is some dog hair in the floor mats that just won't come out. If you have allergies or are not a dog person, this rental might not be the best option.
