Why are there four pillows on hotel beds?

Entering a hotel room and discovering a bed with four pillows may seem excessive at first sight. Yet this well-thought-out disposition combines aesthetics, comfort and practicality. But why such a choice?

The presence of several pillows on a hotel bed contributes to a warm impression of luxury and welcome. A well-stocked bed gives a feeling of visual comfort, creating an inviting and cosy setting. However, their role goes far beyond the decorative aspect.
