Hi Dnewmansf,
It would be somewhat difficult to replicate the Beautiful exactly with a SleepEZ 13000 because the ILD’s would be different but the closest you could come with their standard layers would be two layers of soft and two layers of firm and then you would also need to use their stretch knit cover because the standard cover in the 13000 has wool quilting.
There is more about matching one mattress to another in post #9 here.
Some of the stores that sell PLB mattresses that may be worth talking to as a value reference are in post #32 here.
