Manufacture’s default

I bought a bed on December 2021, I don’t understand why am told to pay because, it’s more than a year I have purchased the bed but when buying the bed you told of a 10 years warranty, I believe the fault in the bed its a manufacture’s default, except for the stains I have on the mattress I think it would have been better if you did put a disclaimer on the warranty, rather than false advertising. Am very dissatisfied that I had to pay for poor workmanship
