Hi jeremyhub,
There is more about the different ways that one mattress can match another one in post #9 here but the Reverie Dream System mattress has a unique design so there won’t be other mattresses that are comparable in terms of their design.
There is more about choosing an adjustable bed in post #3 here and the adjustable bed thread that it links to that can help you decide on an adjustable bed that has the combination of price and features that are important to you.
The mattress shopping tutorial also includes this link to a list of the members here that sell mattresses online and many of them sell latex mattresses that use different types of latex with a range of different designs, options, features, price ranges, and return or exchange policies but the only other one that has custom zoning options is the Flobeds vZone mattresses.
