Why is it often discouraged to flip many modern foam or hybrid mattresses?

Answer

Flipping can disrupt the internal layers and damage the support structure

Modern mattresses are frequently engineered with complex, distinct layers, such as a top comfort layer and a bottom support core. Unlike older mattresses made of simple, uniform stuffing, these beds are designed with a specific orientation in mind. Attempting to flip a modern layered mattress compromises the intended ergonomic alignment and the integrity of the internal components, which may accelerate wear or cause permanent damage to the mattress architecture.
