Business ProfileforKingsdown, Inc. USA

On 9/14/2013, we purchased a Kingsdown mattress with a lifetime warranty. I began to observe some significant changes to the mattress and decided to review the warranty. On 12/29/2023, I contacted Kingsdown Warranty team because the original seller no longer carries the product. They completed an inspection with a third party. On 1/18/2024, I received an email from Kingsdown indicating it was determined there's structural damage to the mattress and it qualifies for a replacement under the warranty terms. We were offered one specific mattress under the warranty terms which is the "closest comparable." I understand that my mattress was likely discontinued long ago. However, it was a very expensive mattress. Since it was a package with an adjustable base, I'm not able to determine the exact cost of the mattress, although I suspect it was $3,500+ retail after discounts. We invested this money due to my significant chronic back pain from injury during my military service.I would like additional information to assist with our decision-making process. From appearances, the offered mattress does not seem similar. Our bed is a eurotop and also much taller. Beyond the explicit warranty, I do believe there's an implied warranty that it would be a similar quality and price range and I would be satisfied with the new product. If I were purchasing a new product, I would have a comfort guarantee, but not with this replacement under the lifetime warranty. I'm weary because all local retailers have discontinued Kingsdown mattresses, so I'm unable to determine the quality. I'm unable to locate any additional information about the offered mattress such as reviews or its cost, except some blogs that speak very poorly of the Body Essentials lineup. I would like additional information to make an informed decision, and also consideration regarding the implied warranty that comes with this product. Why was this product chosen over others? Are there other options not being offered?
