update: successful SN method
SN should work with almost every big name brand, they all request a picture of mattress tag, look around your local marketplaces (facebook/craigslist) and ask seller for a picture of the tag, then check the model on the tag and create a POP for that model. they will also request a picture of mattress with a tape/ruler but just send a normal picture of mattress and keep insisting for a replacement till they fold.

you could also do the donation method with some companies like tuf and needles and avacado. if you request a return you could ask to donate it instead, they will ask for proof of donation but you could go to goodwill and get a blank one for donating anything
