Can you sleep in a Rivian R2?
OfficialYes — people sleep in the cargo area with seats folded. Rivian sells a purpose-built HEST Foamy for R2 (78 × 25 × 3.9 in open). That is manufacturer-confirmed for the vehicle. The calculator below is a separate geometry estimate against community cargo tape (~75 in floor length seats folded, ~41 in between wheel wells, ~31 in height).
Calculated: likely does not fit
Geometry says tight or short vs the ~75 in community seats-folded length, while the SKU is still sold for R2. Prefer the manufacturer confirmation for purchase; use the calculation as a length/width warning for generic mattresses.
Limiting axis: Width between wheel wells — need 78 in, about 41 in available.
