What are the functions of multi-layer detachable pillow cores

source：ptdevesa.com  |  Release time：2025年10月21日
      The core function of the multi-layer detachable pillow core is to flexibly adjust the height and hardness, adapt to the sleep needs of different populations, while also considering cleaning convenience and service life.
1. Adapt to personalized sleep needs
      This is its core function, mainly achieved through the "extraction layer" to achieve bidirectional adjustment:
      Height adjustment: Adjust the number of layers according to sleeping position (low pillow for supine position, high pillow for lateral position) or height, to avoid cervical spine tilting forward due to too high pillow or hanging cervical spine due to too low pillow, and reduce the risk of falling pillow.
      Soft and hardness adjustment: The filling material of each layer of pillow core (such as memory cotton, down, latex) can be the same or different. After being pulled out, it can change the overall support feeling. For example, if you prefer a hard pillow, you can retain the high-density layer, and if you prefer a soft pillow, you can pull out several more layers.
2. Improve cleaning and maintenance convenience
      The traditional integrated pillow core is difficult to clean, but the multi-layer design solves this pain point:
      Local cleaning: If a layer accidentally gets stained (such as sweat or saliva), there is no need to clean the entire pillow core. Simply remove the dirty layer and clean or replace it separately, saving time and water resources.
      Easy to air dry/replace: The single-layer pillow core has a smaller volume, making it easier to dry completely during air drying and avoiding the growth of mold inside; Some products support the replacement of an aging layer separately without the need for overall disposal.
3. Extend the overall service life of the pillow core
      Reduce local losses and indirectly extend product lifecycle through 'layered use':
Relieve stress: During sleep, head pressure will concentrate on the upper part of the pillow core, and long-term use can easily cause the upper layer to collapse. Regularly detach and exchange the positions of each layer to evenly distribute wear and tear.
      On demand update: If a layer of filling material deforms (such as memory cotton aging or down clumping), only that layer needs to be replaced separately, which is more economical and environmentally friendly than replacing the entire pillow core.
