We made FlatCore to solve the slope you feel when sleeping in a Model Y. Its shaped base compensates for the folded rear seats, creating a flatter bed with foam cushioning and adjustable air support for nights in Camp Mode.

Built to level the bed: A tapered profile fills the height difference between the folded seats and cargo floor, with no separate platform needed.

Cushioning with support: Foam softens pressure around your shoulders and hips, while air lets you adjust firmness.

Ready in about 80 seconds: The built-in pump inflates the mattress when it’s time to settle in.

Easier pack-down: The pump draws air out in about 90 seconds before you roll the mattress into its carry bag.

Made for your Model Y: Available in dedicated versions for 2020–2024 and 2025–2026 models.

Core Design Details

Key Features

A Flatter Sleep Surface

The Model Y’s rear seats remain angled when folded. FlatCore’s tapered base compensates for the height difference between the seats and cargo floor, creating a more even sleeping surface without a separate platform.

Soft Touch TPU Surface

Flexible TPU gives the mattress a softer, less plasticky feel than a basic vinyl air bed. It stays pliable when you fold and roll the mattress for storage.

Adjustable Foam-and-Air Support

Foam cushions your shoulders and hips, while the air chamber provides adjustable support. Add air for a firmer surface or release some for a softer feel without changing the mattress setup.

80-Second Inflation

Connect the built-in pump to the vehicle’s 12V outlet to inflate the mattress in about 80 seconds. There is no separate inflator to pack, connect or store after setup.

Ultra Fast Pack Down

The pump draws air out in about 90 seconds before you roll the mattress into its carry bag. Pack it away when you need the rear seats and cargo space again.

For Camp Mode Stays

Use FlatCore as your sleeping surface while Camp Mode manages the cabin climate. The mattress provides cushioning and slope compensation for overnight stops and parked rest.

What real owners are saying

Ali

2025 Toyota RAV4 XLE Owner

"Setup took two minutes, pump included, module charges over USB-C. Fit the RAV4 perfectly with no platform needed, and slept two of us by the lake like a real mattress."

David L.

2022 Toyota RAV4 Owner

"Took the whole family camping in the RAV4 for the first time. Kids were asleep before we finished making dinner, and nobody complained about the ground once."

Jordan M.

2023 Tesla Model Y Owner

"Fits the load floor perfectly, no gaps, no sliding. Woke up in the Sierras on Sunday feeling more rested than I expected from a car."

Mike B.

2020 Ford F-150 Owner

"Twelve hour shifts two hours from any job site. Now I lay the seats down, sleep in the truck, and I am back at it in the morning without the drive home."

Ingrid S.

2024 Model 3 Owner

"Drove through Jotunheimen after a week with no plans. The fit was exact, and the material held up through four nights without any issues."

Lives up to all expectations

Worth the money

Absolutely 100% worth the money. I can position if far enough forward so my feet don't feet the trunk at all (5'11 tall) while not feeling like my head is going to fall off in the front. I'd say this would be comfortable for a person 6'0 up to 6'1 without issue. Very secure, doesn't feel like you're in a car at all, feels like you're 100% on a flat surface with nothing weird underneath you. A little different but probably as comfortable as my $2,000 mattress, although I like air mattresses to begin with!

This mattress is amazing!

Already a fan of the earlier matrass, this new one is spot-on!

As the titles says, i was already a fan of the older matrass by havnby. We took it on a few nights out as parents when we didnt have the kids. We keep it in the frunk so it is always ready to go.

This new version fixed the only downside of the previous model, the slope!
Just got the matrass setup in my car, and yes, the slope is gone. The quality seems to have a little upgrade as well, the added duvet cover feels nice and premium. The added thickness of the matrass is need to counter the slope, it does however give you 'slightly' less vertical room inside the car. I gladly take this downside.

I also noticed when getting out of the car, my legs/body weight would go over the built-in fan, hope it is designed to handle that pressure, for now it seems sturdy enough. The previous model had the fan on the side.

Just a few more weeks untill our holiday, but the smile on my face knowing there is no sliding down the slope anymore will stay.

Thank you Havnby.
ps: Their customer service seems to have improved as well, they are responding in a quick and kind manner. 5 stars!

kind regards,

Scott

Worried this was overkill, but nah, this was worth it

Perfect and worth the price. I was worried this mattress would be overkill, but after sleeping on it for a week, it exceeded my high expectations. Some highlights:
- Very comfy, did not feel like a typical air mattress
- Did not notice the "gap" at the top. mattress did not sag and was well supported. Other Tesla campers I was with noted that their mattresses all had a sag issue at the head. Some folks noted they had to sleep diagonally... no issue with this mattress.
- Inflation, deflation, and refolding was a breeze. I didn't time it but I'd guess 3-5 minutes for fully setting up, or packing up. Typically rolling up a sleeping bag is a big pain, but this was effortless.

Things to note:
- Could still access the trunk side storage. Could not reach behind the driver's seat. Had to move seats forward to really maximize the space. If you're by yourself, use the space next to you to store stuff like a jacket in case you need to get up in middle of night. You can also store stuff in the passenger seat but it's a bit more challenging to reach. It's very roomy if you're just one person. If you're two, it'll be tight.

FAQ

Is this mattress made for Tesla Model Y?

Yes. It is shaped for the Tesla Model Y cargo area and helps offset the folded-seat angle while parked.

Is it good for people who need firmer support?

The 7.5-inch thickest foam section adds firm support across the sleep surface. You can slightly adjust air pressure to fine-tune the feel.

How much battery should I have before sleeping in Camp Mode?

For short next-day driving, plan to start the night around 40-50% battery or higher. For longer drives, start with more margin, especially in extreme temperatures.
