Tesla Mattress for Car Camping

Camper Mode

Best Mattresses For Sleeping In Your Tesla

Now that “camper mode” has been released, you can maintain your climate and stay at your ideal temperature while charging all your devices, so you are able to catch the beautiful sunrise the next morning!

The automaker wrote about “Camp Mode” in the release notes:

Your car can now maintain airflow, temperature, interior lighting, as well as play music, and power devices when Camp Mode is enabled. To enable Camp Mode, tap the fan icon at the bottom of the touchscreen and set ‘Keep Climate On’ to ‘CAMP’ while your car is in ‘PARK.’

The Tesla Model 3 Is Short on Space

  • Model 3 Cargo Space: 43.6 ft³ with seats down
  • Model Y Cargo Space: 68 ft³ with seats down

Due to the fact that the space in the Tesla Model 3 is limited, it is important to have a mattress that maximizes the available space. It is not possible to have a mattress that is too big, otherwise you will run out of space for yourself.

Dreamcase And TESMAT Mattresses Are Designed Specifically For The Model 3 and Model Y

Dreamcase and TESMAT mattresses are made specifically for the Model 3. They’re all-electric and sleep space-saving, but sleep comfortable.

The Model 3 is a very unique design which requires a matching unique mattress.  Both mattresses were designed to support the Model 3 and Model Y, ensuring comfort and rest while protecting the car’s sensitive interior.  Protecting your new asset while maximizing you enjoyment is our objective.

When you fold down the seats in the Tesla Model 3 to make room for the mattress, there are some exposed metal parts (the seat hooks) inside the vehicle. A big concern that both TESMAT and Dreamcase have not yet solved is the likelihood of bumping into the exposed metal at night.

It can potentially result in general inconvenience, or in more severe cases injury.

I think it could be another great add-on if they manage to offer some kind of rubber or fabric that covers the exposed area and protects your body from harm.

How much does it cost to ship the Dreamcase internationally?

I went to the Dreamcase website and calculated the shipping costs to several different international destinations. Dreamcase is based in Kranj, Slovenia and is part of the Internet and mail order industry.

United States

Shipping to the United States costs approximately €69,00 or $84.46 USD, as of this writing.


Dreamcase ships to Canada and prices start at $106.31 Canadian dollars with UPS Express Saver to Ontario, Canada.


UPS standard to UK, France, Italy, Germany and other European countries starts at €33,14 or £29.50.

How much does it cost to ship the TESMAT internationally?

With the TESMAT ordering system I calculated the shipping costs for various international destinations.

TESMAT is based in the United States and shipping is free to most states, but shipping costs apply to states outside the continental United States. Shipping to Alaska or Hawaii costs about $65.97 with USPS Priority Mail or $97.63 with FedEx 2Day.


TESMAT has many shipping options to Canada and prices start at 40 Canadian dollars with FedEx Ground to Ontario, Canada.

Final Thoughts

In Bjørn Nyland’s review of the Dreamcase for the Model 3, he mentions that the set up was a bit clumsy for him. He also mentions that the box of the Dreamcase weighs about 20 kilograms! Yes, that’s incredibly heavy, and it means picking up the box is anything but pretty.

However, my experience with the TESMAT in three parts has made it much easier for me to set up by myself. In addition, the three Z folding rows from TESMAT squeeze easily into its bag and are extremely light. I had absolutely no problems unpacking and packing it thanks to the magnetic clasps.

Another disadvantage of the Dreamcase, as mentioned by Bjorn, is that the pillows being too stiff. Although they contain memory foam, they still feel far too hard for comfort.

TESMAT does not come with pillows. Although you can buy a decent pair by spending just a little more without worrying about overspending, as the mattress is already much cheaper than the Dreamcase.

The TESMAT case is not only lightweight and easy to carry, but also waterproof, so you don’t have to worry about water dripping into the trunk from above when washing your car. And, as already mentioned, it can also be used as a cooler for your drinks, as it’s made of an insulating fabric.

These two products are designed for different people with different needs. TESMAT easily fits in the sub-trunk due to it being designed in three parts. While the Dreamcase does not fit in the sub-trunk.

However, the latter is constructed in a single mattress that unfolds into your bed. They both do an excellent job in their marketing to really capture the stargazing with each car camping setup and beautiful camping spots!

In my opinion, TESMAT is the low-cost and space-saving winner. It will always be my choice in Tesla camping gear. You’re looking at approximately a $528 USD (or €450ish) difference between the memory foam mattress alone.

If you really want to splurge, I recommend you spend the extra $55 USD (approximately €46) for their complete car camping kit which will give you the memory foam mattress & carrying case, sheets and privacy screen (YouTube Setup Video) for your windows.

To be honest, TESMAT is really hard not to recommend. If you are thinking of buying a mattress for your Tesla Model 3 or Model Y, try the TESMAT first. Depending on your hotel budget, you will get your investment back immediately in 2-5 nights, while supporting a small US based company.

Whichever way you go, I recommend folding down the rear seats and making sure you have enough headroom before placing an order. Both products extend to the back of the front seats to give you an idea of how much space you have to work with.

I hope I’ve given you enough information to help you choose a mattress for your Tesla 3 / Y. Leave a comment below if you’ve ever camped with your Tesla. And if you haven’t started yet, I suggest you start Tesla camping today and share your experience with me.

I see these new bed options as a spin-off of Vanlife. #teslacampmode?

Can the three separate mats move out of place while I’m sleeping?

Absolutely not! They will stay put throughout the night since they have Velcro at the bottom which makes them cling to the layer of carpet on the back of the rear seats. Plus, the elastic fitted bedsheets that wrap tightly around the rear seat head rests and underneath the sub-trunk help keep everything in place and completely stable.

Exactly how big is the TESMAT mattress? How tall a person can it easily accommodate?

The exact size of the TESMAT is 75 inches. It is twin sized. A 6 foot 3 inch tall person can easily lie down on it on their back tip to tip. Plus, when you’re lying down on it, your body weight will make the mattress extend past the end a little bit past the rest of your rear seats’ headrests.

Will TESMAT work with my Tesla Model S or X?

Though TESMAT is currently optimized for Tesla Model 3 and Y, you can still fit it inside Model S or X.

Does TESMAT ship internationally?

Yes, it ships around the world. You can enter your shipping address at the checkout to have a look at the shipping cost.

How many amps do I need to stay at a comfortable temperature overnight with the HVAC ON?

5-12 Amps: I have tested using just a standard wall outlet and while this may help reduce the overall range loss overnight, you likely won’t gain any range during your car camping night. You very well will lose range if you’re running the HVAC system. I attached a graph below to illustrate using 12 amps below.

Odds are if you stay overnight at an RV park you can request access to either 30 or 50 amp outlet for charging your EV vehicle. You will us up some of the range gains by running the heating (more so) or cooling (less so) but you won’t need to worry about losing range unless you crank the heat.

Alternatively, you can charge your car up to 90% before you are ready to sleep and remain within 100-125 miles from a Tesla Supercharger, if you’re attempting this during the colder months in a Model 3.

How long does it take to charge my Tesla?

50 AMPS (via NEMA 14-50 or NEMA 6-50):
Model S: 23mi per hour
Model 3: 30mi per hour
Model X: 20mi per hour
Model Y: 29mi per hour

30 AMPS (via NEMA 10-30 or NEMA 14-30):
Model S: 17mi per hour
Model 3: 22mi per hour
Model X: 14mi per hour
Model Y: 21mi per hour

This is information taken directly from Tesla Motors while not using the HVAC system. Keep in mind these numbers will be greatly reduced if you’re trying to keep your cabin cooler (less reduced) or warmer (more reduced) while you’re sleeping on the TESMAT.

Charging Information from TeslaMate

This shows what happens when you connect a Model 3 with 12 amps of charging power while running the heat to the 70s and listening to Bluetooth music over the stereo. The outside temperature was 50F and saw a range loss: 67.57 to 64.15 (3.42 mi loss) over this 1-hour test.
