Can You Sleep in the Back of a Subaru Outback?

The short answer is yes!

This summer, we tried to stick close to home for the most part because of COVID. We drove to South Dakota to visit my Mom for a quick weekend to check in on her. With so much uncertainty around coronavirus, social distancing, and places being closed, my husband and I opted for car camping and sleeping in our 2019 Subaru Outback. We researched ahead of time to figure out the best set-up based on our car’s size and are sharing all the details with you!

Pablo and I like keeping it simple when car camping. We take our dog, sleeping bags, pillows, two camp chairs, camp stove, kitchen gadgets, water, food, cooler, and personal items (clothes and toiletries). Read more about the ultimate list of camp kitchen essentials we pack if you’re interested.

Can a Full-Size Mattress Fit in a Subaru Outback?

You might be wondering how to make a mattress for your Subaru Outback work with what you already have around the house… We did the same thing!

When planning our adventure to sleep in the back of our Subaru Outback, first, we just got in the back of the Subaru without a sleeping mattress or pad. Though doable, we decided it might be better not to wake up sore or stiff. Next, we grabbed an old full-size Coleman blow-up mattress and shoved it into the back of the car. It was suffocating, saying the least. The full-size air bed was too thick, barely giving us room to move, and we could hardly close the door… haha

Since this option was a no-go, we commenced an online research project consisting of “what size mattress fits in the back of a Subaru Outback?”

What Size Air Mattress Fits a Subaru Outback?

So, what size air mattress do you need for a Subaru Outback?

An air mattress with the dimensions 72” x 41” x 4” will fit the back of your Subaru Outback perfectly!

To keep sleeping in the back of the Outback comfortable and straightforward, we found a terrific inflatable mattress!

Best Subaru Outback Air Mattress

The Exped Megamat duo 10 insulated self-inflating sleep pad is the ultimate mattress for a Subaru Outback.

This mattress fits perfectly into the back of our Subaru Outback based on dimensions.

Where to Buy Air Mattress for Subaru Outback?

You can buy the Exped Megamat inflatable mattress at REI or on Amazon.

We actually purchased ours on Amazon with free Amazon Prime shipping.

Check both stores for pricing and to order the correct size – sometimes Amazon has better prices.

These mattresses sell out, so it is always good to check both stores for the correct product size.

Subaru Outback Mattress Test

On the first mattress test, we slept at a Sinclair parking lot in the middle of nowhere Wyoming literally, and it took less than 5 minutes to inflate the mattress. If you do not have time to inflate the bed, it has a little hand pump (see little grey round thing in photos).

We slept well. This air bed was comfortable for the two of us. My husband and I are 5’5” for reference, and we both fit great, especially since we can stuff a bag on each side by the doors for a little extra shoulder room.

The key to comfortably sleeping two people in the back of the car is by stuffing a duffle bag or pillow next to the doors – this makes the shoulder room wider.

This mattress is also perfect for the solo traveler.

The Exped Megamat duo 10 insulated self-inflating sleep pad will not disappoint. It will fit in your Subaru Outback (or SUV), and you will wake up rested.

We looked at so many mattresses online, and when we decided to splurge, it was worth it. That is why we wanted to write this post. I am sure lots of you want a sleeping mattress for the back of your car but are not sure about the size or cost.

Can I Use This Mattress in Other Vehicles?

Of course, as long as wherever you plan to use it has space for a 72” x 41” x 4” inflatable mattress.

This mattress works well in most SUVs or trucks.

You can also use it tent camping or rafting!

Benefits of Sleeping in the Back of Your Car

The cool thing about sleeping in the back of the Subaru Outback is it provides a sturdy shelter option instead of a tent.

You can practically turn your Outback into a camper. You can sleep on the go if you travel across the country (like at truck stops if you want).

The other good thing about sleeping in your car is that if you stay in a place you are not familiar with (like backwoods or a rest stop), you have a little more protection. If you are worried about animals or the weather, sleeping in the car offers a little more comfort.

Sleeping in the back of your car can save quite a bit of money. We are frugal, and we stay where it feels safe and convenient when we are crunched for time or money.

    I have an outback and bought the Exped Megamat 10 M size. I can leave one back seat usable as my lounge chair. I fold down the passenger backseat and middle and the megamat fits perfect for me. I am 5’6” and 60 years old female. It just came yesterday… $150 on sale! Best thing ever, like a real mattress, insulates the cold underneath, 5 year + warranty even if it gets a whole! Easy to inflate with the little hand pump, no sweat! If it doesn’t inflate by itself, just pump it up! Less than a few minutes its inflated! Very compfy, no smell! Wish I had one of these years ago! Its nothing like a blow up mattress I camped with…

    Hi and thanks for this! Do you sleep with closed windows all night, or is there a product for screening out insects?
    Thank you.

      Hi Susan! When we sleep in the mountains out West during the summer, it cools off pretty good, and the bugs usually aren’t bad, so we don’t use a screen to crack the windows. Pablo, my husband, bought a little bug mesh on Amazon with Velcro to use if needed. But we honestly haven’t needed it. If you live where it is kind of buggy, check out some mosquito mesh on Amazon that you can Velcro or easily pin over your windows or sunroof.
