How to Clean and Store Your HEST Memory Foam Mattress Pad

Quick answer

Clean your HEST memory foam mattress pad by spot-treating stains with a mild soap and damp cloth, then air-dry it completely before storing. Never soak the foam or put it in a washing machine. Once dry, roll or fold it loosely and keep it in a cool, dry place away from direct sunlight and heavy compression.

Your HEST memory foam mattress pad is built for years of outdoor comfort, but a little care between trips goes a long way. Memory foam is not machine-washable, so the goal is to remove dirt and moisture without saturating the foam or trapping dampness inside.

This guide walks through the exact steps for cleaning, drying, and storing your pad. Follow them and you will protect the foam's supportive feel, avoid mildew, and make setup faster every time you camp.

Why memory foam needs a different cleaning approach

Memory foam is an open-cell material. If you soak it, water gets inside the cells and can take days to dry, which creates the perfect conditions for mold and odor. That is why washing a camping mattress pad made with memory foam is a spot-cleaning job, not a laundry job.

The same logic applies to heat. Hot water, dryers, and direct sun can break down the foam structure over time. Keep every step gentle and room-temperature, and your pad will keep its shape and rebound.

• Never submerge memory foam in water or put it in a washing machine.
• Avoid harsh chemicals, bleach, and abrasive brushes.
• Always dry completely before storing, even if it feels dry on the surface.

Gather the right supplies first

You do not need a specialty kit. A mild dish soap or gentle laundry detergent, two clean microfiber cloths, a spray bottle of plain water, and a soft-bristle brush cover almost every situation. For odors, a light sprinkle of baking soda works well and vacuums or brushes off easily.

If your pad has a removable cover, check the care tag before doing anything else. Some covers can be machine washed on cold and air-dried, while others should be spot-cleaned like the foam itself. When in doubt, treat the cover as gently as the foam.

• Use only a few drops of soap in a bowl of cool water.
• Keep a dry towel nearby to blot excess moisture immediately.
• Work in a shaded, well-ventilated area, not in direct sun.

Step-by-step cleaning routine

Start by unzipping or removing the cover if your model has one, then shake the pad outdoors to remove loose dirt and sand. Vacuum both sides with a brush attachment, or use a soft brush, to lift dust from the surface. Mix a few drops of mild soap into cool water, dip a microfiber cloth, wring it out until it is barely damp, and blot stains from the outside in.

Rinse the cloth with clean water, wring it again, and wipe away soap residue. Do not rub hard; blotting protects the foam surface. For stubborn spots, repeat the blotting process rather than adding more soap. Once clean, press a dry towel over the damp area to pull out as much moisture as possible.

• Common mistake: using a soaking-wet cloth. It should feel damp, never dripping.
• Checkpoint: if the foam feels wet to the touch, you used too much water.

Drying without damaging the foam

Lay the pad flat on a clean, dry surface in a shaded, airy spot. A drying rack or a couple of chairs works well because air can move around both sides. Flip the pad after a few hours so the underside dries evenly. Depending on humidity, full drying can take 24 to 48 hours.

Never use a dryer, a heater, or direct sunlight to speed things up. High heat can warp memory foam and weaken the bond with the drop-stitch base on models like the Hest Sleep System. If you are in a hurry, point a room-temperature fan at the pad instead.

• Common mistake: storing the pad while it still feels cool or damp in the center.
• Checkpoint: press the thickest part of the pad. If it feels cold or clammy, keep drying.

Storing your camping mattress pad between trips

Once the pad is completely dry, roll or fold it loosely. Tight, long-term compression can leave creases in memory foam, so avoid strapping it down harder than necessary. Store it in a breathable cotton bag or a loosely closed storage sack rather than a vacuum-sealed plastic bin, which can trap moisture.

Keep the pad in a cool, dry, dark place such as a closet or gear shelf. Avoid hot garages, damp basements, and direct sun. If you store it under other gear, place it on top or against a wall so it is not crushed. For long storage, check it every few months and air it out if needed.

• Common mistake: storing a damp pad in a plastic bin, which invites mildew.
• Checkpoint: label the storage bag with the date you put it away so you can rotate gear.

Keeping accessories and companion gear clean

Your pad works as part of a system, so clean the pieces that touch it. The HEST Pump is packable and easy to use for fine-tuning firmness on the drop-stitch base of the Sleep System; wipe it with a damp cloth and let it dry fully before packing it away. The HEST X KOA Camp Pillow has a removable cover on many models, so check the tag and spot-clean or wash it according to the instructions.

If you use a Foamy Seat Cushion or the HEST Dog Bed For Rivian, give those the same treatment: blot stains, air-dry completely, and store loosely. Keeping every piece dry and clean prevents odors from spreading between items in your gear bin.

• Clean the pump and pillow at the same time as the pad so nothing goes into storage damp.
• Store small accessories in a mesh bag so air can circulate.

Your 6-step HEST mattress care routine

1. 1. Shake and vacuum: Remove the cover if possible, shake the pad outdoors, then vacuum both sides with a brush attachment or soft brush. Checkpoint: no visible grit or sand left on the surface.
2. 2. Spot-clean with a barely damp cloth: Mix a few drops of mild soap in cool water, wring the cloth until it is barely damp, and blot stains from the outside in. Common mistake: soaking the foam. It should never feel wet through.
3. 3. Rinse and blot: Wipe away soap residue with a clean damp cloth, then press a dry towel over the area to pull out moisture. Checkpoint: no soap film or suds remain.
4. 4. Air-dry flat in shade: Lay the pad flat in a shaded, ventilated spot and flip it after a few hours. Allow 24 to 48 hours depending on humidity. Common mistake: using a dryer or direct sun, which can damage the foam.
5. 5. Roll loosely and store breathable: Once fully dry, roll or fold the pad loosely and place it in a cotton bag or loosely closed sack in a cool, dry, dark place. Checkpoint: the pad feels completely dry in the thickest part before storage.
6. 6. Refresh every few months: During long storage, unroll the pad, air it out, and check for dampness or odors before your next trip. Next step: if you notice a musty smell, repeat the spot-clean and drying steps.

Product facts that affect care

• Hest Sleep System: The flagship mattress pairs temperature-resilient memory foam with a supportive, durable outdoor-ready drop-stitch base, and comes with a packable memory foam pillow. The drop-stitch base should be cleaned and dried separately from the foam top, and the included pillow needs the same spot-cleaning care.
• HEST Pump: The HEST Pump is packable and easy to use for fine-tuning firmness and adjusting air on the drop-stitch base of the Sleep System. Wipe the pump clean and dry it fully before storage so it does not introduce moisture or grit to the base next trip.
• HEST X KOA Camp Pillow: The HEST X KOA Limited Series Camp Pillow is a collaboration with KOA and features a camp print on the best-selling Camp Pillow. Check the care tag before cleaning; spot-clean the foam and follow the cover instructions to preserve the print and loft.

A few gentle habits keep your HEST memory foam mattress pad fresh, supportive, and ready for the next trip. Spot-clean promptly, dry completely, and store it loosely in a breathable spot. Your future self will thank you on the first night out.
