What distinguishes a smart mattress from an earlier adjustable bed?

It uses new data to refine output autonomously (closed-loop)

The fundamental engineering breakthrough defining the smart mattress is the implementation of a closed-loop feedback system. An older adjustable bed, such as those that allowed manual head or foot elevation or even early airbeds like the Sleep Number, operates on a simple input-output basis: the user inputs a setting, and the bed adjusts the pressure or position accordingly. A true smart mattress elevates this by performing an additional, critical step: it measures the immediate outcome of its action, such as pressure distribution or body position, using sensor arrays. This new data is then autonomously fed back into the system's algorithms to refine and correct the adjustment in real-time, ensuring continuous, self-guided optimization for uniform comfort.
