Should you buy a used mattress? How to check for bed bugs, age and wear

A used mattress is where the usual Marketplace rule, see it before you pay, stops being enough. You can see a sag or a stain. You usually can’t see bed bugs until they are in your bedroom. So the inspection matters more than the price.

Should you buy a used mattress?

For most people, no. The saving over a budget new mattress is small next to the misery of bed bugs, and no photo can rule them out. A few cases do make sense.

Health Canada is blunt about it: “Never take a mattress or sofa from a curb.” Curb finds can be great for a solid wood table (see curb alerts); a mattress is the exception. Crib mattresses come with safe-sleep rules of their own, covered in our used baby gear guide.

How to check a mattress for bed bugs

This method joins the US Environmental Protection Agency’s list of hiding places to Health Canada’s inspection steps. Ask the seller to strip the bed before you arrive, and bring a bright flashlight.

1. Lift each corner and check the underside and the edges.
2. Follow the piping and seams all the way round, top and bottom.
3. Check every tuft, button and the tag, running a fingernail or an old card along each crease.
4. Inspect the box spring: its folds and seams, and the edges where the fabric is stapled to the frame.
5. Look at the bed frame and headboard joints. EPA’s rule of thumb: “If a crack will hold a credit card, it could hide a bed bug.”

EPA’s signs to look for: rusty or reddish stains from crushed bugs, dark spots about the size of a bullet point (•) that bleed into fabric like a marker, eggs and eggshells about 1 mm long, pale yellow skins that young bugs shed, and live bugs. One spot ends the visit, whatever the price. A clean check lowers the risk without removing it, since an early infestation is easy to miss, so wrap and encase it anyway. A seller who won’t let you lift the mattress has answered for you. Sofas and chairs get the same treatment in our used furniture guide.

How to tell how old a mattress is

Read the label. In the US, the Consumer Product Safety Commission requires every mattress to be permanently labelled with the month and year it was made. Look for the sewn-in law tag, the one with the famous “do not remove” warning, and ask for a photo of it before you drive over. “Two years old” on a label dated six years back tells you about the mattress and the seller. A gap of a few months is just warehouse time.

The Better Sleep Council, an industry group, says a mattress set that is seven years old has in general “reached the end of the line”. Treat seven as the outer limit: at five, most of its life is gone, and the price should say so. No label, or one cut off, means the age is unknown. Treat it like a curb find.

Wear, stains and smells

Comfort and hygiene take minutes to test.

• Lie on it in your sleeping position for a few minutes. Your back finds a dip before your eyes do.
• Lay a broom handle across it; body impressions show as a gap underneath.
• Sit on the edge. If it collapses, you will roll toward it every night.
• Press memory foam in and let go. A dent that stays is worn foam.
• Smell the middle, where people sleep. Smoke, pets and damp soak into foam and don’t air out.
• Push the box spring at several points for squeaks, and look for cracked slats.

The Better Sleep Council lists visible sagging, tears, holes and stains among the signs a mattress needs replacing.

Is it legal to sell or buy a used mattress?

Buying one is legal, and no US federal law bans selling a used mattress. Federal rules cover how mattresses are made: flammability and the permanent date label.

Some states regulate businesses. Pennsylvania requires secondhand dealers, auctioneers, renovators and rental businesses that sell or rent used bedding to register, disinfect each item with an approved disinfectant and attach a yellow law label with their registration and permit numbers. That is aimed at businesses, so a person selling their own bed won’t have one, but a refurbished mattress from a Pennsylvania store without it deserves questions. Meta’s Commerce Policies restrict used cosmetics yet have no section on mattresses or bedding. Rules vary by state and province, and this is general information, not legal advice.

“Brand new in plastic” mattresses

Search for a queen and you will see one seller post “brand new, still in plastic” a dozen times, well under store prices. That is a business clearing returns or overstock. Some are fine. Check five things:

1. The brand and model. Look up the new price, and whether that model exists at all.
2. The photo. Google Lens shows whether it came from a brand’s website.
3. The mattress itself, before you pay: plastic not opened and taped back, label present, a recent date.
4. The warranty. Assume there is none. Tempur-Pedic’s covers only the original purchaser of a new product from an authorized seller, and it is “not transferable to anyone who subsequently purchases the product from you.”
5. The delivery. Health Canada notes that new mattresses are often delivered in the truck that carries away old ones, so an unwrapped one has travelled with strangers’ beds.

Getting it home clean

1. Wrap it at the seller’s door in a mattress bag, or plastic sheeting and tape, before it touches your car.
2. Unwrap it outside or in the garage and check it again in daylight.
3. Fit light-coloured zippered encasements on the mattress and box spring. EPA says encasements eliminate many hiding spots, and the light colour makes bed bugs easier to see.
4. Vacuum the car or truck bed afterwards.

What to pay for a used mattress

Start from what the same model costs new today, not what the seller paid. “Paid $1,800” means little four years into a seven-year life. Then subtract for the warranty that stays with the first buyer, the age, what your inspection found, and the bag, encasement and truck you will pay for. A free mattress is no bargain if it brings bed bugs. Our guides to fair prices and negotiating cover the offer itself.

Scams and red flags

Most mattress scams come down to paying before you see anything. Meta’s advice: “Never pay for an item in advance. Avoid sellers who request payment before providing the item.” Watch for a deposit to hold it or a delivery fee up front (the deposit scam), shipping only from a seller who claims to be local (shipping scams), a phone number or “text me” in the listing, gift cards or wire transfers (safer payment methods), and stock photos with no picture of the label.

Finding a used mattress near you

On a computer, Facebook Marketplace can show only mattresses you can collect, newest first:

1. Search facebook.com/marketplace for your size, such as “queen mattress”.
2. Click your location in the left column, enter your postal or ZIP code and pick a small radius.
3. Set Delivery method to Local pickup to drop shipped bed-in-a-box listings.
4. Set Sort by to Date listed so the newest come first.

In the app, these sit under Filters and can reset with each search; our local only guide has the details. Free mattresses are at facebook.com/marketplace/category/free and in Kijiji’s Free Stuff category, and the curb rule still applies (free stuff guide).

How Sift helps

Sift is a free browser extension for Facebook Marketplace. There is no account, it works right in Chrome (also Edge and Brave) on a computer, and it takes a minute to set up. It clears the noise and points at listings that need care, and the bed bug check stays yours.

• Hide shipped and partner listings (local only) removes “Ships to you” bed-in-a-box listings from every search, and a distance limit from your home puts the distance on each card.
• Require “queen”, or your size, and block topper, crib, “air mattress” and “mattress protector” (how blocked words work). Sift can hide dropshippers too.
• A seller who will only ship a mattress gets a Ships only flag, and Sift flags the other common warning signs as well, such as Pay first or Off-site contact (every flag). Mattress stores posting their stock get a Dealer tag.
• Sift marks price drops and history, shows whether a price looks fair compared with similar listings on a one-model search, and links every listing to Google Shopping and Search by image.
• Only free listings skips $0 posts that really want a price. Watch a search and new listing alerts send a desktop notification when something new passes your filters, while your browser is running.

Getting rid of your old mattress

In California, Connecticut, Oregon and Rhode Island, the Mattress Recycling Council’s Bye Bye Mattress program takes old mattresses statewide. Elsewhere, try your city’s bulk pickup or the store delivering the new one. If yours had bed bugs, bag it and write that on the bag, so nobody carries it home.
