Hi DeputyDawg,
No … their convoluted layer is 28 ILD which is more durable than softer ILD’s and the convoluting gives it a softer feel than the same ILD in a solid layer.
Generally no with a quilted cover but the convoluted layer can also be used with either side up.
All the layers of a mattress interact together and the 2" convoluted layer is only part of the comfort layers in combination with the layers below it (particularly the next layer down) so the choice of layers underneath the convoluted layer would be an important part of your choice.
It depends on the specific materials and components but with latex which is very flexible anything up to about 12" or so would generally be fine and even something a little thicker would still bend easily with the adjustable bed although it wouldn’t bend quite as easily as a thinner mattress.
One of the challenges of a site like this is that you have more and better choices to choose between and when you are down to final choices between “good and good” (which you are) and there is no clear winner or any “mistakes” in terms of quality or value then it’s really a matter of deciding between all the objective, subjective, and intangible factors that are the most important part of your personal value equation and making the “best judgement” choice that you feel best about.
