Question: how much should i sell a used queen size mattress for?
Answer: Generally speaking, a used mattress will command a resale price that is roughly equivalent to 20% to 30% of the original product price. If a mattress originally costs $1,000, then expect to resell it for $200 to $300; if the original cost is $2,000, then the resale price will probably fall between $400 and $600.
