1. The core structure of the shredded memory foam pillow is the accumulation of small pieces of foam
Filled with memory foam particles after cutting (not whole foam)
The particle size is usually like soybeans or peanuts, loose and flowing but with some support
2. Dynamic support characteristics
Particles flow automatically with head and neck pressure, filling the gaps in the body's curves
More easily shaped than traditional memory foam, with less noise when turning over
3. Adjustable personalized design
Most of them come with zipper lining, and the filling amount can be adjusted to adjust the height/softness
Suitable for people who are highly sensitive to pillows (such as those with cervical discomfort)
4. Differences from traditional memory cotton pillows
Whole piece memory cotton: one-piece molding, supporting and fixed, suitable for people who are accustomed to not deforming
Broken memory foam: flexible to adapt to changes in sleeping posture, but long-term use may cause particle breakage
5. Target audience
Suitable for: side sleepers, those who require dynamic cervical support, and those who prefer adjustable pillows
Not suitable for: people who are accustomed to super hard/super flat pillows and dislike manually adjusting the filling amount
6. Maintenance features
Not washable, can only be ventilated for mite removal or locally cleaned
After 1-2 years of use, it may be necessary to add new particles (old particles may be crushed and thinned)
