Hi cbcb,
I think the information I’ve included in your other thread should help (I wrote it before I saw this post).
I would keep in mind too that all the layers together are part of the quality and value of a mattress and while the gel itself is a very high quality and durable material … it’s only one of the layers and all of them together will be part of both the performance and quality, value, and durability of this mattress.
