Latex Bliss-Nutrition vs others based on quality only.

Hi TD-Max,

You are certainly asking the right questions to help you narrow down your choices.
WG&R furniture is the retailer local to you that carries the PLB but they are also the factory that makes it for the region. They are still making the old version and have no specific plans to switch so for now it seems unlikely that you would find a place to test the new version.

You could always add a thin topper if it became necessary.

They do have very low cost layer exchanges but as you mentioned the layer thicknesses and ILD’s are slightly different (they are “one step” up for their soft and medium which is not a large jump). Layer thickness also acts in a similar way to layer softness so more thickness does make a layer (or a mattress) feel softer which would “close the gap” yes.

Mainly for two reasons. First they have several suppliers which may not have exactly the same ILD rating for soft, medium, or firm so the range is a catchall that fits different material choices (2- 3 ILD would not be perceptible for most people) but also because ILD is never an exact number and there is a range firmness levels both across the surface of a layer and between different layers that are rated the same ILD (see post #6 here).
