Hi mdc1022,
I’m not personally familiar with the mattress no.
The most important part of the “value” of a mattress purchase is how well it matches your specific needs and preferences in terms of PPP (Posture and alignment, Pressure relief, and Personal preferences).
Outside of the suitability of a mattress … the next most important part of the “value” of a mattress purchase is the quality of the construction and the materials inside it. The name of the manufacturer on the label means nothing because all manufacturers have access to similar materials and make a wide variety of mattresses and some may be worth considering and others I wouldn’t consider at all. To me the most important factor of a “brand” is how transparent they are and how willing they are to disclose the information you need to make an informed choice (see this article for a listing of the top 15 manufacturers).
In the case of Comfort Solutions (King Koil) … they are a licensee brand made by different private factories across the country (who may each make their mattresses differetly) and some of their licensee factories are more transparent than others. No matter how suitable a mattress may be for you when you first purchase it … if it uses lower quality materials in the upper layers then these materials can soften, compress, or break down too quickly relative to the price you paid and the loss of comfort and support which is the reason you purchased it in the first place isn’t covered by any warranty. I would keep in mind that a warranty only covers defects and has little to nothing to do with the useful life of a mattress.
Outside of suitability and durability … the other parts of your personal value equation that are most important to you (including the price of course) would also be an important part of the “value” of a mattress purchase.
To me … “brand shopping” is among the worst ways to choose a mattress because knowing the name of the manufacturer doesn’t tell you anything about what is inside the specific mattress you are considering.
Mainly to prevent consumers from making meaningful comparisons between different stores that carry the same mattress under a different name so when they tell you they will “beat” any price on the same mattress … there are none that are the same.
