Summarize this article:

When selling a used mattress, you are likely to net a much lower price than the original retail value—even if the mattress is in new or like-new condition. People looking to buy a used mattress are hoping to get a good deal, so they will not be willing to shell out retail prices. However, determining the original retail value can provide a good starting point for figuring out the market value of your mattress. If your mattress is in new or nearly new condition, try selling it for roughly 70-80% of the original retail price. If you are unable to sell it for that much, you may need to reduce the price even further. Do some research on websites like Craigslist and eBay to get an idea of the typical price range for used mattresses like yours. Look at mattresses of roughly the same size, age, brand, and condition. This will give you a realistic idea of what you can expect to get for your mattress. Age and wear will have a significant impact on the value of your mattress. If your mattress is more than a couple years old or has any obvious stains or damage, you will likely not be able to get very much for it. A mattress that has been slept on every night may also sell for less than a barely-used mattress from a guest bedroom. Used furniture calculators can help you get a ballpark idea of how much your mattress may be worth on the resale market. These calculators take into account factors such as the condition, brand, age, and original price of your item. While you ultimately may not be able to sell your mattress for the price suggested by the calculator, these calculations can provide a helpful starting point for setting a reasonable price. Try a calculator like Bluebookfurniture.com or the Aptdeco.com furniture calculator. Once you have an idea of the average resale price range for mattresses like yours, decide on the minimum you are willing to accept. For example, if mattresses similar to yours sell for between $250 and $400 on eBay, set your minimum price at $250. If you are unable to sell your mattress for the price range you settled on, you may need to reassess your minimum and go lower.

Summary:
Look at the original retail value of your mattress. Compare your mattress to similar used mattresses for sale online. Take your mattress’s age and condition into account. Use an online furniture value calculator to get a ballpark figure. Decide on a minimum price.
