Yes, this is most definitely a SCAM. Our $1k Simmons Beauty Rest began to sink 18 months after purchase.
After talking to the retailer and getting an inspector out, the mattress was deemed defective and replaceable, so they offered a new one. However, suddenly with 5 years still left on our warranty they will not replace because there is a "slight discoloration" on the opposite side of the bed. We used recommended $100 gortex mattress covers since new keeping this mattress in absolute TOP condition. It looks so good that the 3rd part inspector they sent out marked it as clean.
They are a HORRIBLE company that has zero ethical sensibilities. Stay away from their faulty products and BS warranty.
Monetary Loss: $1000.
