Is one example of this PLB (looking at their mattress specs from your previous post). Is this why they separate the 14-15 ILD Talalays as mattress toppers? So the toppers can be replaced as necessary without having to refurbish the entire mattress?
I was debating getting a custom mattress and thought about having 15 ILD Talalay as the final comfort layer, but would I be better off just leaving that out of the mattress, and getting it as a separate topper?
Thanks
