Buying secondhand is a great way to save money, especially if you’re shopping for furniture, household goods, or everyday essentials. But not every used item is worth bringing home, even if the price seems too good to pass up.
Some things can hide damage, hygiene problems, or safety concerns that are hard to spot at a quick glance. Others may end up costing more than buying new once you factor in repairs, missing parts, or professional cleaning.
Before picking up your next thrift store or garage sale find, check these 12 things carefully.
1. Mattresses
A used mattress might look clean on the outside, but you can’t tell how well it was cared for or where it was stored. Dust mites, mold, stains, odors, and signs of bedbug activity can be difficult to spot just by looking at the surface.
Since you spend hours sleeping on your mattress every night, buying a new one is usually the better choice. Even a mattress that looks barely used can come with problems you won’t notice until it’s already in your bedroom.
2. Upholstered Furniture
A secondhand sofa or armchair can look like a great bargain, especially if the fabric is still in good shape. But cushions and upholstery can hold onto pet hair, odors, dust, stains, and allergens from years of use.
You also risk bringing home bedbugs or other unwanted pests. If you find a piece you really like, check the seams, cushions, frame, and underside before deciding to buy it.

3. Baby Cribs
A used crib might save you some money, but baby furniture isn’t something to buy without doing your homework. Older models may have outdated safety features, recalled parts, missing hardware, or damage from previous use.
Check the manufacturer’s name and model number against current safety information and recall notices before considering a used crib. If you can’t verify its history or confirm that it meets current safety standards, buying new is the safer option.
4. Car Seats
A secondhand car seat can be risky because you may not know what it’s been through. It could have been involved in a crash, stored in extreme temperatures, recalled, or kept past its expiration date.
Missing parts and unclear installation instructions can also create problems. Unless you know the seat’s complete history and can confirm that it meets current safety guidelines, it’s better to buy a new one.
5. Rugs
Used rugs can be a good deal, but don’t let a clean-looking surface fool you. Dirt, pet stains, odors, mold, and even pests can hide deep in the fibers or underneath the backing.
Flip the rug over, check the edges, and look for discoloration, damage, or a musty smell before you pay. A cheap rug may not feel like much of a bargain if it needs professional cleaning or has problems you discover after bringing it home.
6. Pillows
Pillows collect a lot over years of regular use, including sweat, body oils, dust mites, and allergens. They can also lose their shape and support, making them less comfortable than they appear.
Since pillows are relatively inexpensive to replace, there’s little reason to risk one with an unknown history. It’s one of those purchases where starting fresh makes more sense.
7. Used Tires
A used tire can look perfectly fine at first glance and still have problems that affect how safely it performs on the road. Uneven wear, hidden damage, previous repairs, age, and improper storage can all affect its condition.
Since tires play such a big part in your vehicle’s handling and stopping ability, don’t buy them based on appearance alone. Have a qualified tire professional inspect them before you buy, and skip any tire with a questionable history.
8. Swimwear and Underwear
Buying used swimwear and underwear isn’t everyone’s idea of a good secondhand find, mainly because of hygiene concerns. These items are worn close to the skin, and you may not feel comfortable knowing how they were previously used or cared for.
New options are often inexpensive, especially during sales, so the savings may not be worth it. If you’re shopping secondhand, this is one category that’s usually better left alone.
9. Nonstick Cookware
A secondhand nonstick pan might seem like an easy way to save money, but check the cooking surface before buying it. Scratches, peeling, chips, and worn areas can be signs that the coating has deteriorated.
If the surface is damaged, leave the pan behind rather than hoping it will still work fine. A new pan with an intact coating is a better purchase than one with an unknown condition and care history.
10. Stuffed Animals
That cute stuffed animal at the thrift store may look perfectly harmless, but soft toys can collect dust, pet hair, odors, and allergens over time. They may also have loose buttons, plastic eyes, damaged seams, or small parts that could be unsafe for young children.
If you’re buying one for a baby or toddler, a new toy is often the better choice. For older children, inspect the entire toy and check the washing instructions before bringing it home.
11. Puzzles
Used puzzles can be a fun, inexpensive find, but some pieces may be missing. A box may look untouched until you get home, open it, and discover that the previous owner lost a few pieces along the way.
Check whether the puzzle is sealed or ask the seller if all the pieces are accounted for. Nothing is more frustrating than spending hours putting a puzzle together only to find out it isn’t complete.
12. Untested Appliances
Thrift stores and garage sales often have plenty of small appliances, including coffee makers, blenders, toasters, hair dryers, and televisions. Some are barely used, but others may have worn-out parts, electrical problems, or motors that are close to giving out.
Ask if you can plug in the appliance and test it before paying. If testing isn’t allowed and there’s no return policy, think carefully about whether the low price is worth the risk.
