One of the best parts of sleeping in your car is that you aren’t carrying your bed on your back. So, you can splurge on heavier, cushier mats, pillows and blankets. Fold your back seats down flat to create a bed space. In the Jeep, we use the inflatable queen mattress from Intex, which is a super affordable option that fits myself, my husband, and my young son. Pair it with sheets and blankets in the summer, or a sleeping bag in winter. For a smaller car and when it’s just me and my husband, we tend to use my camping set up of REI Co-op Stratus sleeping pads along with the Exped Dual Sleeping Bag, which perfectly fits the Stratus sleeping pads.
