Komfortstufen

Komfortstufen refer to a classification system for measuring the level of comfort provided by different types of car seats and seats in general. The term "Komfortstufen" is German, meaning "comfort stages." The system categorizes seats into various levels of comfort, typically ranging from minimal to maximum.

The measurement of comfort is subjective and is usually based on factors like seat cushioning, back support, and adjustability. Manufacturers often use various materials and cushioning technologies to achieve the desired level of comfort. Seats with better cushioning, lumbar support, and adjustable headrests are considered higher in comfort level.

There are five commonly recognized levels of comfort, also referred to as "Komfortstufen":

K1: The lowest level of comfort, offering minimal cushioning and support.

K2: Provides more basic comfort features, including firmer cushioning and adjustable headrests.

K3: Step-up in comfort, with higher-density foam, increased back support, and sometimes cooling or heating functions.

K4: Higher-end seats with flexible lumbar support, and usually embedded with climate control features.

K5: The highest level of comfort, achieves enhanced ergonomics, flexibility and the highest clearance for genuine adaptation.

The extent to which these comfort stages apply to other objects, such as office chairs or mattresses, is less defined but thought to be somewhat similar in meaning.
