Hi passat,
I switched your post to your previous topic with the same title.
I would need to know the details of what is inside a mattress you are considering. If you can find out the information listed here from the retailer and post it on the forum I’d be happy to make some comments about the quality of the materials or any possible weak links in any of their mattresses you are considering.
The better options and possibilities I’m aware of in the Olympia area are listed in post #5 here.
There is more about pressure mapping systems in post #4 here and post #2 here. In general I would treat them as an aid but they wouldn’t be the primary basis for my choice … especially if they are only linked to a specific line of mattresses.
