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.

Comfort should not take longer to set up than the drive.
