In contrast, the AS4 may cater to those who prioritize a soft mattress feel. Customer reviews show varied preferences, indicating that personal experiences may significantly influence satisfaction levels.
Durability: Both models utilize high-quality materials, but the construction of the AS3 may provide better long-term durability for users requiring more support. The AS4, while comfortable, may wear faster under heavier use conditions.
