How to Wrap a Mattress for Moving and Storage

Two things ruin a mattress in storage, and neither one is dirt. The first is standing it on its side for weeks, which lets the springs and foam settle sideways into a shape they don't come back from. The second is sealing it in plastic while it's even slightly damp, which is how you get mildew inside a mattress you cannot open up and clean.

So: a proper mattress bag, taped closed, stored flat. Here's the full method.

What you need

• A mattress bag sized to your mattress. They're a few dollars at any moving supply or hardware store. Get the right size — a queen bag on a king is worse than nothing.
• Packing tape. Not duct tape, which will pull the surface fabric when you remove it.
• A second person. Genuinely. A king mattress is not a solo job and this is how people hurt their backs.
• Optionally, a cardboard mattress carton if it's an expensive mattress going into long storage.

Step 1: Strip it and let it dry

Take everything off — sheets, protector, topper. Then vacuum the surface and both sides with the upholstery attachment, edges and seams included.

Now leave it in a dry room with air moving over it for a few hours. If you've spot-cleaned anything recently, or the mattress has been in a room with a swamp cooler or a damp garage, give it a full day. A mattress holds more moisture than it looks like it does, and sealing that in is the mistake that costs you the mattress.

Don't do this in a garage on a humid morning in a coastal city. Do it inside.

Step 2: Bag it

1. Stand the mattress on its long edge, with one person holding it.
2. Slide the bag over the top corner and pull it down. Bags are easier to pull down than to push on.
3. Work the corners into the corners of the bag. Don't leave the mattress diagonal inside a baggy sleeve — loose plastic snags and tears.
4. Lay it flat, fold the open end over like you're wrapping a gift, and tape it shut.
5. Tape the seams too. Run tape along the length of any seam in the bag. Dust and insects get in through seams, not through the plastic.

If you're storing more than a couple of months, put a few silica or desiccant packs inside the bag before you seal it. Cheap, and they handle whatever residual humidity is in there.

Step 3: Store it flat

This is the rule people break, because flat takes floor space and on-edge doesn't.

Innerspring mattresses: stored on their side for months, the springs take a set and the edge support sags. You'll feel it.

Memory foam and latex: worse. Foam is essentially a very slow liquid. Left on its edge for weeks, it will develop a permanent lean, and there is no fixing it.

Pillow tops: the top layer compresses toward whichever side is down. On edge, that means the padding migrates to one long side.

So: flat. Ideally on top of something rather than directly on a container deck.

Step 4: What it sits on and what sits on it

• Get it off the floor. A pallet, a few 2x4s, or the flat top of a dresser or box layer. Anything to keep it off a deck where condensation collects.
• Nothing heavy on top. A mattress is not a shelf. Bedding, pillows, lampshades, empty suitcases — fine. Boxes of books — no. Weight left on one spot for months leaves a dent.
• Nothing sharp near it. Bed frame rails, table legs, and the corners of headboards will punch through a bag on the first bump. Blanket-wrap the frame or keep it on the other side of the container.

The box spring, frame and headboard

Box springs are rigid, so they're the one piece you can stand on edge without harm. Bag it the same way and let it be a divider wall in the container.

The frame: bag the bolts and hardware in a ziplock and tape it to a rail, or better, tape it inside a drawer of the dresser that's going in the same load. A frame with no hardware is a trip to the hardware store on a day when you have no time.

Headboards, especially upholstered ones, get a moving blanket, not plastic. Fabric under sealed plastic is the same mildew problem as the mattress.

Getting it out of the house without wrecking it

• Carry it on edge, store it flat. On edge is fine for the ten minutes it's moving; it's only a problem as a resting position.
• Don't bend it. Folding an innerspring damages the springs. Some foam mattresses tolerate a gentle bend for a doorway, but don't crease it.
• Doorways. Two people, one at each end, tilt and pivot. Take the door off the hinges if it's tight rather than forcing it.
• Don't drag it. The bag will shred on stucco, concrete and thresholds.

This is one of the real advantages of loading into a container in your own driveway: you carry the mattress twenty feet and set it down, instead of hauling it into a rental truck, driving it across town, and wheeling it down a facility hallway. Same principle as wrapping a couch for moving — the fewer times a big soft thing gets handled, the better it comes out.

The moisture question in a container

A sealed steel container is dry inside, but it's not climate managed, and anything you put in damp stays damp. So the rules are simple:

• Never bag a mattress that isn't fully dry. This is the whole ballgame.
• Desiccant packs inside the bag for anything over a couple of months.
• Off the deck, on a pallet or a layer of boxes.
• If you're near the coast, hanging moisture absorbers in the container itself are worth the few dollars.

Should you even store it?

Blunt answer: a mattress that's already eight or nine years old, sagging, or that you were planning to replace anyway is not worth storing for six months. You'll pay to store it and then replace it on the other end.

A good mattress that's two or three years old is absolutely worth wrapping properly. So is anything you paid real money for.

If you're storing a whole bedroom, the mattress is the piece that determines the layout — it goes in flat, near the top, on a solid layer, and everything else works around it. The general method is in how to load a storage container, and sizes are in what fits in each container size.

Short version

Vacuum it, dry it fully, bag it in a real mattress bag, tape the seams, add desiccant, store it flat and elevated, and put nothing heavy on it. Do that and it comes out of a six-month store exactly the way it went in.
