A practical walkthrough for setting up the HEST Dog Bed for Rivian in your vehicle and keeping it fresh through camping season, with fit checks and cleaning steps.

Quick answer

Unroll the HEST Dog Bed for Rivian, place it in the cargo area or on a seat, and let the memory foam expand. After trips, spot clean or vacuum the cover and air-dry it fully before rolling it back up. Check that the bed sits flat and does not block seat latches or cargo anchors.

Why fit matters more than size alone

The HEST Dog Bed for Rivian is designed to fit in all Rivian vehicles, but every dog settles differently. A bed that slides on a smooth cargo floor or bunches against a seat back can make your dog restless. Before you commit to a spot, test the bed in both the cargo area and the rear seat with your dog's normal posture in mind. If your dog likes to stretch out, a flat cargo floor usually works better than a contoured seat. If your dog curls up, a seat may keep them closer to you and reduce sliding.

Cleaning without breaking down the foam

Memory foam should not go in a washing machine or dryer. For routine dog bed care while camping, shake out loose dirt, vacuum the surface with a brush attachment, and spot clean stains with a mild soap and damp cloth. If the cover is removable on your model, follow the care label; if it is not, keep the foam out of standing water. After any damp cleaning, let the bed air-dry completely in a shaded, ventilated area before rolling it up. Storing it damp is the fastest way to get mildew smell.

Rolling and storing between adventures

The HEST Dog Bed for Rivian rolls up easily for portability, but rolling it tightly for long-term storage can compress the foam. For daily use, a loose roll is fine. For off-season storage, keep it unrolled or only loosely folded in a dry place. If you already carry a HEST Foamy mattress and Camp Pillow, the HEST Foamy Duffel 120L is built to carry a full HEST setup including a Foamy mattress, pillow, and bedding, so it can also hold a rolled dog bed alongside your sleep gear. That keeps dog gear and human gear in one place instead of loose in the trunk.

Setup and care steps

Unroll and let the foam expand: Take the HEST Dog Bed for Rivian out of its rolled state and lay it flat in the cargo area or on a seat. Give it a few minutes to regain full loft before your dog uses it. Checkpoint: if the foam still looks compressed after 10 minutes, it may have been stored rolled too tightly for too long.
Test placement with your dog: Put your dog on the bed in your preferred spot. Watch for sliding, bunching, or blocking of seat latches, cargo anchors, or the tailgate. Adjust forward or back until the bed sits flat. Common mistake: placing the bed over a cargo floor tie-down or seat hinge, which can create a lump under the foam.
Secure for travel: If your dog tends to pace, tuck the bed against a seat back or cargo wall so it cannot slide forward. Do not place it on top of loose gear that can shift. Checkpoint: with the vehicle parked, push the bed sideways. If it slides more than a few inches, reposition it.
Clean after every trip: Shake out dirt, vacuum the surface, and spot clean with mild soap and a damp cloth. Avoid soaking the memory foam. Let it air-dry completely before rolling. Common mistake: rolling up a damp bed, which traps moisture and causes odor.
Store loosely between adventures: Keep the bed unrolled or loosely folded in a dry, ventilated space. If you use a duffel, put the dog bed in first and avoid compressing it under heavy gear. Next step: if you also carry a Foamy mattress and pillow, use the HEST Foamy Duffel 120L to keep your full setup together.
