Real Mattress Feel

High-density foam adds the kind of steady support thin air pads cannot give. Less sag, less wobble, more sleep-after-the-drive comfort.

<2 min

Ready to Rest

The built-in pump gets the mattress ready in under two minutes, so setup still feels quick at camp.

Lie flat, even when your cargo floor doesn’t.

Folded rear seats weren’t made for sleep. FlatCore is shaped to help level out the RAV4 cargo area, creating a flatter surface for two people to stretch out, rest deeper, and wake up ready for the road ahead.

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.
