Article in English: Even if you think your mattress is old and no one will want it, others may think otherwise. List your mattress for a reasonable price on websites and/or apps like Craigslist, eBay, and Letgo and see if anyone shows interest in purchasing it. To improve your chances of attracting potential buyers, provide quality photos of the mattress and an include an accurate item description. Check with nonprofit organizations in your area to see if they can accept your mattress as a donation. Some of these organizations, like Salvation Army and Goodwill, may not be able to accept your mattress. However, it’s a good idea to check with Habitat for Humanity, local churches, homeless shelters, and thrift stores to see if they can. Mattress disposal has become quite an issue, so many retailers and manufacturers often take on the task of disposing of them for customers. If you’re purchasing a new mattress, ask the retailer if they’d be willing to take your old one and dispose of it properly. If you have access to a vehicle that can transport a mattress, roll it up, tie it down, and transport it to a local recycling center. You can drop your mattress off for free and they’ll break it down for you. If this sounds like too much of an inconvenience, you can also hire a mattress recycling service to come pick the mattress up from your home, break it down, and recycle the parts for as low as $50-100. Go to earth911.com or byebyemattress.com to find a recycling center near you.
