Hi mjester,
Mattress design and “theory” can sometimes be counter intuitive and some layer changes can have surprising results.
Part of the reason for this is the partly subjective nature of people’s experiences on a mattress, part could be from differences in the firmness of Dunlop latex layers, part of it could be the different types of “softness” that some people are more sensitive to (see post #15 here), and part could be for other reasons that aren’t as obvious.
In some cases and for some people for example … using firmer layers on the bottom of a mattress can “force” more of the compression to the top of the mattress which some people will perceive as softer.
The good news is that you had the foresight to purchase a component mattress which gives you some good fine tuning options after a purchase (instead of making an “all or nothing” purchase) and to deal with a manufacturer who goes out of their way to help their customers and has a history of doing everything possible (within reason and what is possible of course) to make sure their customers are happy.
For the minority of people who need to make changes to their layering with a component mattress it can sometimes be a little frustrating but it’s worth it in the end to find the combination that you will do best with.
Again … I’m looking forward to any further updates you have the chance to share.
