How To Store A Mattress: Expert Tips For 2026

Store your mattress flat, clean, dry, sealed, climate-controlled, and lifted.

You want your mattress to feel great after storage, not lumpy or musty. I have helped dozens of clients put beds away for moves, remodels, and long trips. In this guide, I explain how to store a mattress step by step. You will learn what to buy, where to put it, and mistakes to avoid. If you want clear, proven advice on how to store a mattress, you are in the right place.

Why proper storage matters

A mattress holds weight and moisture over time. If you store it wrong, it can sag, mold, or smell. Some damage cannot be fixed.

Foam and springs shift if the bed leans for weeks. Plastic can trap moisture. Heat and high humidity speed up wear. When you know how to store a mattress, you protect your back and your money.

Most makers warn that poor storage can void a warranty. Storing flat, clean, dry, and supported is the safe path. That is the core of how to store a mattress.

Supplies checklist for how to store a mattress

Get your tools ready first. This saves time and keeps the bed safe during the move and storage.

Mattress storage bag or full encasement that breathes
Heavy-duty tape for sealing edges
Furniture sliders or a dolly
Mild fabric cleaner and a spray bottle
Vacuum with upholstery tool
Baking soda for deodorizing
Silica gel packs for moisture control
Clean sheets or moving blankets
Pallets or a platform to lift off the floor

Tip from the field: Skip thin, crinkly plastic for long storage. Use a breathable encasement and add silica gel. Use thick plastic only for short moves.

Step-by-step: how to store a mattress the right way

Follow these steps to do it once and do it right.

Check the label and warranty. Some brands list storage rules. Storing upright long term or using plastic may void the warranty.
Deep-clean the surface. Vacuum both sides. Spot clean stains with mild cleaner. Sprinkle baking soda, wait 8–12 hours, then vacuum again.
Dry fully. Let it air until bone dry. Sunlight is fine for a short time, but avoid long UV exposure.
Bag and seal. For long-term, use a breathable encasement or storage bag. Tape seams closed. For short trips, a thick plastic bag is okay, but open it once stored.
Add moisture control. Place silica gel packs inside the bag near corners. This reduces condensation risk.
Move with care. Do not fold unless the maker allows it. Foam can crease. Use a dolly. Keep it flat while moving when you can.
Store flat on a platform. Use pallets or a slatted base. Keep 4–6 inches off the floor for airflow.
Keep it clear. Do not stack boxes on top. Weight can cause dents and coil shift.
Control climate. Aim for 60–70°F and 30–50% humidity. Avoid attics, damp basements, and metal sheds.
Check monthly. Look for moisture, tears, or pests. Replace silica gel if needed and keep the area clean.

This is the safest, proven way for how to store a mattress. It prevents sag, mold, and odor.

Best places and conditions for how to store a mattress

Climate control matters a lot. Foam and fabric hate heat and damp air. A steady, cool, dry room works best.

Good spots:

Climate-controlled storage unit
Spare room with AC and a dehumidifier
Clean, dry garage with sealed floor and a dehumidifier

Avoid:

Attics and sheds with big heat swings
Unsealed basements with damp floors
Outdoor storage without climate control

If you must use a garage, raise the bed high and use a vapor barrier under the platform. A fan on low helps with airflow. These tips are core to how to store a mattress in tough spaces.

Storage tips by mattress type

Not all beds act the same. Here is how to store a mattress by type.

Innerspring

Store flat with light support across the whole base.
Do not bend or tie it to fit a car. Coils can kink.

Memory foam and polyfoam

Store flat. Never fold unless the maker says you can.
Foam can crease and may not bounce back if bent for long.

Latex

Store flat and cool. Heat ages latex faster.
Use a breathable cover. Latex traps moisture if sealed in plastic.

Hybrid

Treat like foam and springs. Keep flat and well supported.
Do not put weight on top.

Futon and roll-up pads

Air out, then roll loose with a breathable strap.
Check monthly and re-roll to avoid flat spots.

These details matter when planning how to store a mattress for months or longer.

Short-term vs long-term: how to store a mattress safely

Short-term storage (under 2 weeks)

You can store it on its side for a few days. Keep it secured and straight.
A thick plastic bag is fine. Open it once stored to breathe if longer than a week.

Medium-term (2 weeks to 3 months)

Store flat only. Use a breathable encasement.
Add silica gel packs. Check every 4 weeks.

Long-term (3+ months)

Use climate control and a breathable encasement.
Keep off the floor with even support. No weight on top. Inspect monthly.

I once stored a queen upright for 3 months during a remodel. It looked fine, but the edge softened and felt wavy. Since then, I only store flat. That experience shapes my advice on how to store a mattress.

Mistakes to avoid when you store a mattress

Save yourself a headache by skipping these common errors.

Leaning upright for months. This causes sag and tilt.
Sealing in plastic for long storage. Moisture gets trapped and grows odor.
Stacking heavy boxes on top. This dents foam and coils.
Storing on the floor. Floors collect moisture and pests.
Skipping cleaning. Odors set in and are hard to remove later.
Ignoring climate. Heat and humidity shorten mattress life.

These traps explain why people ask how to store a mattress the right way. Avoid them and you will be fine.

Ongoing care while your mattress is stored

Check on the bed now and then. Small moves can prevent big damage.

Inspect the bag for tears or loose tape.
Swap or dry silica gel if it has turned pink or clear.
Wipe dust from the platform so airflow stays open.
Rotate the mattress 180 degrees every 1–2 months if it is flat. This evens pressure points.

This simple routine is a key part of how to store a mattress for the long haul.

Unwrapping and reusing after storage

Bring it back to life the right way.

Move it to a clean, dry room. Keep it flat.
Open the bag and let it breathe for 24–48 hours.
Vacuum both sides with an upholstery tool.
Deodorize with baking soda if needed. Vacuum after a few hours.
Inspect for signs of mold, pests, or sag. If you see mold, do not sleep on it.
Place it on a supportive base. Add a breathable protector.

If you stored it flat and dry, it should feel like new. This end step matters as much as the start in how to store a mattress well.
