Level Sleep Surface

FlatCore helps turn sloped folded seats into a level sleep surface, correcting vehicle-seat angles that can reach up to 12°.

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.

A flatter place to sleep in your CR-V.

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. Steady rest.

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 pump. No loose parts.

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.

Compact storage for gear-heavy weekends.

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.
