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.
2007 Honda ElementShannon's Honda1553
Shannon's awesome Honda Element is perfect if you wanna go on a road trip and have a place to sleep all in one. She has customized that back of the element by taking out the back seats and adding a platform which fits a full size futon pad that she provides perfectly. With storage underneath the platform and included window covers it makes it super comfortable to sleep in.
Shannon was very nice and the Element was in great shape. The sleeping platform came in handy as we were able to camp in the car and see the Grand Canyon. Matress pad recommended if you want to try this.
