Hi Kmfl98,
In a two sided mattress and with a good design … this would be a very durable mattress and a mattress that is “finished” on both sides is certainly a value bonus as well. How well it feels and performs as well as all the other parts of a mattress purchase that are important to you (see post #2 here and the post it links to) would also be a significant part of it’s “value”. You can see some of my comments about a similar mattress that uses 1.5 lb polyfoam at the end of this post. Everything is relative to what else is available to you and you are certainly correct that this would be much better quality/value than the mainstream mattresses you could buy in this price range although $1600 is also in the range of some one sided latex hybrid mattresses so it really does depend on what is most important to you in your personal value equation.
I can tell you that you are looking at better quality and value than the large majority of people end up purchasing a major brand or a mattress sold at a chain store but whether it is the “best” available to you only you can decide and will depend on what else you are comparing it to and what is most important to you.
