What Is the Best Way to Store a Mattress?
Sep 4, 2026 / Alyssa Duranty
Store a mattress by cleaning and drying it fully, placing it in a fitted mattress bag, and laying it flat on a clean, level, raised surface. Keep boxes, furniture, and uneven weight off the mattress, and leave enough room to retrieve it without moving unrelated items.
A storage unit can help when a mattress, bed frame, furniture, and moving boxes take up more room than you want to use at home during a move, renovation, or transition between homes.
Mattress Storage Essentials:
- Clean and dry the mattress fully before storage.
- Remove sheets, mattress pads, pillows, and other bedding.
- Use a fitted mattress bag or mattress box during moving and storage.
- Store the mattress flat on a clean, level, raised surface.
- Keep the mattress off the floor.
- Avoid placing boxes, furniture, or uneven items on top.
- Move larger mattresses with help when practical.
- Measure doorways, hallways, elevators, and the storage-unit entrance before moving.
- Use climate-controlled storage when comparing options for fabric-covered mattresses and bedroom items.
Mattress Storage at a Glance:
What Is the Best Way to Store a Mattress?
The best way to store a mattress is to clean and dry it, place it in a fitted mattress bag, and lay it flat on a level surface. Storing a mattress flat can help it maintain its shape during a longer storage period.
Remove bedding, mattress pads, and other accessories before packing. Use a fitted bag that matches the mattress size, and secure loose bag edges without taping directly to the mattress.
How Should You Clean a Mattress Before Storage?
Clean a mattress before storage by removing bedding, vacuuming the surface, and treating small spots according to the mattress manufacturer’s care guidance. Use minimal liquid during cleaning so the mattress can dry fully before storage.
Use this process:
- Remove sheets, mattress pads, pillows, and blankets.
- Vacuum the mattress surface, seams, and edges with an upholstery attachment.
- Spot-clean small areas according to manufacturer guidance.
- Blot the surface instead of soaking it.
- Leave the mattress in a well-ventilated indoor area until fully dry.
- Check seams, edges, and quilted sections for remaining moisture.
Do not place a damp mattress into a bag or storage unit.
How Can You Move a Mattress Without Bending It?
Move a mattress with another person when practical, especially for queen, king, and California king mattresses. Larger mattresses can be difficult to guide through doorways, stairwells, elevators, and corners without bending or dragging them.
Before moving day, measure:
- Mattress length, width, and height
- Doorways and hallways
- Stairway width and turns
- Elevator dimensions
- The route from the bedroom to the vehicle
- The route from the vehicle to the storage unit
A mattress can stand on its side briefly during loading or unloading. For longer storage, lay it flat whenever possible.
Is a Mattress Bag or Mattress Box Better?
A mattress bag and mattress box can both work during a move or storage project. The better option depends on the move distance, available packing supplies, and whether the mattress will travel near other furniture.
Use a mattress bag when you need a lightweight cover for a clean, dry mattress. Consider a mattress box when the mattress may move near furniture, walls, doors, or other items during transport.
Should You Store a Mattress Flat or on Its Side?
Store a mattress flat for longer storage. A flat position supports the mattress across its full surface and can help prevent leaning, bowing, or uneven pressure.
Stand a mattress on its side only temporarily while moving it through a doorway, loading it into a vehicle, or unloading it. Do not fold a mattress unless the manufacturer specifically states that it is foldable.
What Should You Put Under a Mattress in Storage?
Place a mattress on a clean, dry, level, raised surface. A pallet, mattress rack, platform, or other stable base can keep the mattress separated from the floor while supporting it evenly.
Before placing the mattress, check that the base is:
- Clean and dry
- Level and stable
- Large enough to support the full mattress
- Free from sharp edges and protruding hardware
- Away from walls with visible moisture concerns
Keep the top of the mattress clear. Do not place furniture, boxes, or uneven items on it.
How Should You Store a Mattress With a Bed Frame?
Store a mattress with a bed frame by disassembling the frame when the manufacturer’s instructions allow it. Keep rails, slats, headboards, footboards, and hardware grouped together in a designated bedroom-furniture area.
Place screws, bolts, brackets, and other hardware in labeled bags. Store bed-frame components beside the mattress, not on top of it.
Use labels such as:
- Bed Frame Hardware
- Bedroom — Mattress and Bed Frame
- Queen Bed Slats
- Headboard and Footboard
- Bedroom Furniture — Retrieve Soon
Should You Use Climate-Controlled Storage for a Mattress?
Climate-controlled storage can be useful for mattresses made with foam, fabric, springs, natural fibers, and layered materials. High heat and changing humidity can affect foam, fabric covers, adhesives, and internal mattress materials over time. Humidity can also contribute to moisture-related odors when a mattress is packed away before it is fully dry.
More than 90% of Public Storage properties offer climate-controlled units. These units are designed to help maintain more consistent temperature or humidity levels than non-climate-controlled storage.
Clean and dry the mattress fully, use a fitted mattress bag, place it flat on a raised surface, and keep heavy boxes and furniture away from it.
Do You Need Drive-Up Storage for a Mattress?
Drive-up storage can be useful for a mattress because mattresses, box springs, bed frames, and bedroom furniture can be large and difficult to carry through hallways or elevators. Vehicle access near the unit can shorten the distance between your vehicle and the storage space.
More than 45% of Public Storage properties offer drive-up access units.
Choose drive-up storage when you plan to:
- Load a mattress directly from a vehicle
- Move a box spring, bed frame, headboard, or dresser
- Make several trips during a move or renovation
- Store bedroom furniture with the mattress
- Retrieve the mattress without carrying it through a long building route
Measure the mattress and the longest bed-frame component before reserving. Use the Public Storage size guide to compare available unit sizes and leave room for a clear walkway.
How Should You Organize a Mattress in a Storage Unit?
Organize a mattress in a designated bedroom-furniture area. Keep the mattress flat, place bed-frame pieces beside it, and arrange boxes so they do not press against the mattress bag.
How Should You Prepare a Mattress After Storage?
Prepare a mattress after storage by moving it into a clean, dry room, removing the bag, and allowing the mattress to air out before adding bedding. Inspect the mattress surface, seams, and edges before placing it on a bed frame.
Vacuum away any dust if needed, then add a clean mattress protector and bedding. Follow manufacturer guidance if the mattress has changed shape or has a noticeable odor.
Store a Mattress With a Clear Plan.
A mattress is easier to store when it is clean, fully dry, covered with a fitted bag, and laid flat on a raised, level surface. Keep uneven weight off the mattress, organize bed-frame components nearby, and leave a clear route for moving it when needed.
Find a Public Storage location near you to reserve climate-controlled storage or drive-up storage for mattresses, bed frames, bedroom furniture, and moving boxes.
A clear mattress-storage plan makes the next bedroom setup easier to organize.
