I have heard people have good success with the pickup return method.

Most mattress companies have free trials and free returns. Use it for 2-3 weeks and make a return, say you don’t like it. They’ll hire a third party company that recycles / donates the mattress. When they come to pick it up tell them that you decided you’re gonna keep it.

Tell the mattress company they picked it up and you’re waiting for your refund.

This would work if they didn't ask for pick-up confirmation. In my country they do exactly how you described but they also want proof of the pick-up (by the 3rd party company) in order to issue a refund
