Transform your Rivian R1S into a premium mobile basecamp with the only officially co-designed mattress and pillow system built specifically for electric vehicle camping. The HEST Foamy for R1S delivers home-level comfort with custom-fit memory foam that perfectly frames your R1S wheel wells—no gaps, no shifting, just premium sleep anywhere you roam.
Whether you're overlanding through the backcountry, camping at national parks, or spontaneous road-tripping, HEST's Rivian R1S mattress system turns your electric adventure vehicle into a comfortable sleeping sanctuary. With an industry-leading R-value of 8.8 and premium CertiPUR-US certified foam, this is the upgrade every Rivian owner needs.
Co-designed with Rivian and sold on their official Gear Shop. This is the only mattress Rivian trusts enough to put their name on—custom-fit for the R1S dimensions with precision-cut wheel well cutouts.
Unlike EVBASE, Amazon, and other air mattresses that deflate overnight and puncture on gravel, HEST uses two layers of CertiPUR-US memory foam. No pumps, no leaks, no 3 AM wake-ups on a flat mattress.
Custom-shaped with curved cutouts that frame the R1S wheel wells perfectly. Generic mattresses like Exped MegaMat leave gaps and don't maximize your sleeping space. HEST uses every inch.
Built-in connectors securely link two Foamy R1S mattresses together to create a full double bed with zero gap. Solo campers can use one and save cargo space. Your choice.
8.8 R-value provides superior insulation from cold cargo floors. Stays comfortable in freezing temps while air mattresses turn rock-hard and conduct cold. Perfect for winter camping in your R1S.
Rolls up compactly to store in your R1S frunk, leaving your entire cargo area free for gear, coolers, and adventure equipment. Built-in phone pockets keep devices accessible overnight.
The Rivian R1S is one of the best vehicles for car camping, with 74 inches of length when seats are folded flat, built-in climate control, and massive onboard power. Here's how to maximize your R1S sleeping space with HEST:
