Core Design Details

Key Features

The floor isn’t flat. This is.

Model Y rear seats fold with a slope. FlatCore is shaped to take that slope out of the night, so you’re not sliding toward the hatch or building a platform in the dark. Just a level place to sleep, already fitted to the car.

Quiet against skin. Tough enough for camp.

The surface feels closer to technical gear than a plastic air bed. Smooth, low-noise, and easy to live with inside a closed cabin, whether you’re sleeping in base layers, a bag, or sharing the space with a dog after a long day outside.

Support you can sleep on.

Air gives the structure. Foam takes the edge off. Together they make a surface that doesn’t bounce like a pool float or sag like soft foam. It feels steady, quiet, and comfortable enough to make the second day better than the first.

No extra pump. No extra step.

The pump is built in, so setup doesn’t depend on loose cords, adapters, or digging through the frunk after dark. Inflate in about 80 seconds, adjust by feel, and deflate when it’s time to move.

Packs down before the rest of camp goes in.

Space disappears fast in a Model Y. Chairs, cooler, duffels, water, layers, tools. FlatCore compresses into its carry bag and fits in the frunk or cargo area, leaving room for the gear that makes the trip worth taking.

Camp Mode keeps the air right. FlatCore fixes the ground.

The Model Y already makes a good shelter. FlatCore makes it a better place to sleep. Fitted to the cargo area, level where it needs to be, and ready for the woods, the coast, the desert, or wherever you stop for the night.

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."
