What changes when you move up
More or different comfort material can make the top of an adjustable-air mattress feel noticeably plusher even before you change the air setting. That is why the best model is not automatically the most expensive one.
How to choose
Choose the lower-numbered option if you prefer a more direct, less cushioned surface. Move toward the plusher option when you want more material between you and the adjustable support core.
What not to over-read
Merchant feel labels are useful orientation points, not objective firmness scores. Body size, sleep position, sheets, protectors and the chosen air setting can all change how the bed feels.
