Amerisleep AS5 vs Sleep Number 360 c2 Smart Bed: What Actually Differs
The Amerisleep AS5 is a memory foam build, while the Sleep Number 360 c2 Smart Bed is a smart bed — that single difference drives most of the cooling, motion, and feel decisions below.

The Sleep Number 360 c2 Smart Bed is the firmer of the two at 5/10 (medium), and the Amerisleep AS5 sits at 3.5/10 (medium-soft) — a meaningful enough gap that sleeper position and weight should drive the choice.

Cooling rating not available for one or both mattresses — spec not available.
Durability and edge-support ratings not available — spec not available.
Softer at 3.5/10 vs 5/10 — lighter sleepers compress less, so they typically need the softer of two options to get proper contouring.
