If your mattress is still in clean, usable condition, you might want to try reaching out to local charities. Churches and shelters may take a gently used mattress off your hands, although you may have to transport the mattress yourself. Otherwise, a junk hauling service should be able to take away your mattress. You might also want to check if your new mattress includes white glove delivery. That’s where the delivery team will not only set up your new bed but remove your old mattress and donate or dispose of it.
