Core Design Details

Key Features

CR-V Leveling Fit

Folded seats leave gaps, height changes, and slope. FlatCore is shaped to help support the sleep surface from the cargo area forward, so you can stretch out with less improvising after a long drive.

Dense Foam Support

High-density foam adds the support car campers actually need: less bounce than a basic air mattress, more structure than soft camp foam, and enough cushion to make the next morning feel better.

Built-In 12V Pump

The pump is built into the sleep system, so setup stays simple at camp, at a trailhead, or after dark. Inflate, adjust by feel, and deflate when it’s time to move.

Gear-Friendly Storage

Coolers, chairs, duffels, water, layers, space goes fast in a CR-V. FlatCore compresses into its carry bag, leaving room for the gear that makes the trip worth taking.

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."
