Key Features

Levels the Space Beneath You

FlatCore uses a vehicle-shaped support base to compensate for the RAV4’s folded-seat incline, creating a flatter sleep surface than a standard pad placed directly on the cargo floor.

Hybrid Support That Feels More Like A Real Bed

Air alone can feel bouncy. Foam alone can bottom out. FlatCore combines air structure with supportive foam cushioning, giving you stable, hotel-like comfort that upgrades car camping from “good enough” to genuinely restful.

Built-In Pump. No Outlet Hunting

Skip the extra pump, loose cords, and campsite power scramble. The rechargeable built-in pump inflates and deflates fast, so you can turn your RAV4 into a sleep setup in under two minutes.

Soft-Touch TPU For Nights Inside The Car

Your sleep surface should feel like outdoor performance gear, not a plastic pool float. FlatCore uses skin-friendly TPU with a smoother handfeel, so your car bed feels cleaner, quieter, and more comfortable after a long day outside.

Packs small, because gear space matters.

Camp chairs, coolers, duffels, recovery gear, layers, food, water — the trunk fills up fast. FlatCore packs down like a large gym bag, saving space without making you choose between better sleep and the rest of your kit.

Open the hatch. You’re at basecamp.

Wherever the day ends, your RAV4 becomes a place to reset. Stretch out, recover from the miles, and wake with the energy to hike farther, drive longer, and do it all again tomorrow.

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."
