Hi TnTWalter,
You can read a little more about the different ways that one mattress can “match” another one in post #9 here.
There is also more about the specs of the PLB Beautiful here so you would need to use similar layering (type of latex, ILD, and layer thicknesses) and have a similar cover to have a reasonable approximation with another mattress.
If you talk with Shawn at SleepEz he will be able to help you choose the options they offer that are closest to the PLB Beautiful (probably S/S/F/F in blended Talalay) although this may not be the best choice for you in terms of PPP and they also don’t have the exact same layers available as part of their standard designs. The 13000 also has a good quality wool quilted cover but you may also want to ask them about using a stretch knit cover as well if coming as “close as possible” to the Beautiful is the most important part of your personal value equation even though you may not be able to have an exact match.
The Flobeds is a different design and they use a 2" convoluted latex top layer (or optionally a solid layer). They would also be well worth talking to though about which of their options would be closest to the Beautiful because they are also very knowledgeable and experienced with different latex combinations. They also have a good quality wool quilted cover.
As far as I know … Plushbeds doesn’t use Talalay latex in their support cores and they use 100% natural Talalay in the comfort layers which comes in different ILD ranges than blended Talalay and has a slightly different “feel” as well although they would also be the best source of information about which of their options they believe would come closest to the Beautiful.
