What Shape of Headrest is the Most Comfortable?
1 Answers
For adults, the length of a pillow should be between 40~60cm, while those over 70cm provide more noticeable and comfortable side support for the head. The width should preferably not be less than 30cm to ensure that both the head and neck are properly supported during sleep, providing adequate support for the cervical spine. Below is relevant information about headrests: Introduction to Headrests: Automotive seat headrests, also known as neck rests, are auxiliary devices designed to enhance the comfort and safety of car passengers. Classification of Headrests: Seat headrests are categorized into fixed and adjustable types. In high-back seats, the headrest is integrated with the seatback and is non-detachable. These high-back seats are primarily used in buses, such as coaches. In low-back seats, the headrest is separate from the seatback and is attached using single or double pins inserted into sockets on the seatback. These low-back seats are commonly found in passenger vehicles, such as sedans. Low-back seat headrests can be either adjustable or fixed, with adjustable types further divided into manual or electric adjustments for height and angle. Most passenger vehicle headrests are adjustable to better fit the neck and back shape of the occupant, improving safety. Some luxury sedans feature front-row headrests with electric four-way adjustments (up, down, forward, backward). In economy models, headrests are typically manually adjustable or fixed, with manual adjustments often limited to height. From a safety perspective, adjustable headrests are preferable to accommodate passengers of different heights.
