The Rivian R1S is a natural basecamp. With the rear seats folded flat, the cargo area provides a spacious, flat sleeping surface perfect for car camping. HEST makes a purpose-built Foamy specifically for the R1S — designed to fit the exact cargo dimensions so you're not guessing at sizing.
Recommended setup: Foamy For R1S
The Foamy For R1S uses the same 3.9" enhanced memory foam as all HEST mattresses — no pump, no inflation, no setup. Unroll, unclip, and sleep. Pair it with a HEST Camp Pillow for a complete sleep kit that fits entirely in your cargo area.
The R1T's truck bed was made for adventure, and with the tailgate down it becomes one of the best outdoor sleeping platforms available. HEST recommends two options depending on your height and whether you're sleeping solo or with a partner.
Recommended setup — two sleepers or tall solo: Two HEST Foamy Regulars linked side-by-side using the integrated clips create a 78" × 50" sleeping surface. With the tailgate down, this fits perfectly in the R1T bed.
Recommended setup— compact/solo: Two HEST Foamy Shorts linked side-by-side create a 64" × 50" sleeping surface, fitting within the bed without needing the tailgate down.
Storage tip: Both setups roll up compactly and fit in the R1T's frunk for transportation — keeping your truck bed completely clear when you're not camping.
The Rivian R2 is the more compact member of the Rivian family but it's still a capable car camping platform. The Foamy For R2 by HEST is designed specifically for the R2, turning the back of your EV into a comfortable, custom-fit sleep system. Built with temperature-resilient memory foam and a durable waterproof base, it rolls compact for storage in the frunk and deploys quickly when it's time to rest. Secure it between the front seat and back platform using the integrated headrest attachment. Link a second mattress to create a full double sleeping area.

Like all HEST mattresses, it rolls up using the integrated compression harness when you need your seats back — taking up minimal space in the R2's cargo area.
HEST makes a purpose-built Foamy For R1S designed specifically with the Rivian R1S in mind. It mimics the curvature of the R1S, stores in the frunk, and deploys quickly in the cargo area.
