Mattresses In most cases, you should steer clear of old mattresses and box springs at the thrift store. Mattresses naturally gather things like allergens and dust mites from the previous owner, and you'll never know what caused a stain. The bed bug risk is also always a worry. Apart from being gross, mattresses also conform to the first owner's body and sleeping position. This will leave the bed lumpy and uncomfortable for you.
