Manufacturer's warranty
We bought this mattress Serta I-comfort firm hybrid mattress for $2200 from a local store in May 2024. This was a replacement for a 20-year old Denver Signature mattress. The Serta was very good at first. 2 months later it started to be too soft on my side. (It caused back pain). We turned it around, and now the other side has started to soften, 2 months later. (I’m not heavy.)We went to the [store] office in October 2024. They showed us a newer version (Extra Firm) for $1700.Also they sent a gentleman to inspect the mattress. He stretched a red rope across from one side of the mattress to the other. The middle section must dip by at least one and a half inches to qualify as defective. He even called the company. As a result, the warranty does not cover the replacement of my mattress. Who sleeps in the middle of a queen-sized mattress?!I learned not to buy any mattress without a 6-month return or exchange policy in writing. Buyers: beware of the warranty trap.Let me it clear. This is not the [local company's] fault – it is the manufacturer’s warranty that is the problem.
