Invest in a breathable, waterproof barrier — this is your first line of defense against stains, allergens, and accidental spills. Even if you’re only sleeping on it for a few nights, a lightweight, breathable shield keeps sweat, dust, and debris from seeping into the core. Choose one made of breathable, waterproof fabric to avoid trapping heat and promoting odor buildup.

Dust your mattress regularly — if you’re staying put for more than a week, spend just five minutes to run a handheld vacuum over the entire area. This removes dead skin, hair, AC repair and duct cleaning allergens that gather surprisingly fast — don’t overlook the edges and seams, where particles linger.
Keep food and beverages away from your mattress. Crumbs and spills are the primary culprits behind staining. Moisture seeps deep into padding and create hidden pockets of decay over time. Drink only plain water and consume food away from your bed.
Let your mattress air out — when you wake up, strip the sheets and let it ventilate. Sweat and humidity can get sealed in by bedding, leading to musty odors and mildew. Turn on a portable air circulator to reduce moisture buildup and keep things fresh.
Turn your mattress every few weeks — Certain models are non-flippable, but if yours allows flipping, swap ends every few weeks to avoid permanent indentations. This is especially important if you always sleep in the same spot.
Neutralize smells naturally — dust lightly across the surface of arm & hammer powder over the mattress, leave it overnight for tough odors, then use a handheld cleaner. For stubborn odors, use an odor-neutralizing gel or sachet to clean the surrounding air.
Avoid damaging conditions when not in use. If you’re moving often, avoid damp basements or garages. Cold and humidity can damage the core structure. Use a dry, flat surface and cover with a breathable cotton sheet to protect while allowing airflow.
Don’t wait for pain to act — sagging, lumps, or dipping after just a few months mean it’s no longer serving you. Don’t endure discomfort. Restorative slumber is essential for well-being, no matter how short your stay.
Stick to these practical steps, you can extend the life of any mattress — in a temporary rental — and sleep better every night.
