Release time:
2026/01/15
The choice of cushion core filling material primarily depends on the intended use and specific requirements. Below is a comparison of common materials:
1. Pearl cotton
Features: Excellent resilience, becoming fluffier with each use; relatively high cost.
Applicable scenarios: Suitable for areas with frequent contact, such as small cushions and lumbar pillows.
2. Shaped cotton
Features: Unique design, good service life and elasticity; however, some manufacturers may use scrap materials bonded together to cut costs, which can compromise quality.
Applicable scenarios: Suitable for areas requiring shaped support, such as sofa cushions.
3. Spray-glued cotton
Features: Excellent plasticity; the longer the fibers, the better the quality. It reduces friction between the fabric and the sponge, enhancing the smoothness of the seating experience.
Applicable scenarios: Suitable for large pillows and cushions.
4. Doll cotton (PP cotton)
Features: Soft and comfortable texture, provides support for the spine, typically made of 3A fine filaments with a density of 30. It feels smooth and silky to the touch, is relatively inexpensive, and offers excellent warmth retention.
Applicable scenarios: Suitable for areas requiring soft support, such as pillow cushions.
5. Down filling
Features: Excellent fluffiness, comfortable seating experience, resistant to deformation over long-term use; however, slow rebound and high production costs—typically used in combination with foam.
Applicable scenarios: Suitable for areas that require long-term comfortable support, such as sofa cushions.
6. Memory foam
Features: Offers precise support, ideal for both office and automotive settings.
Applicable scenarios: Suitable for areas requiring precise support.
7. Hollow cotton
Features: High cost performance and easy machine-wash maintenance.
Applicable scenarios: Lumbar support suitable for office and automotive environments.
Summary: Choose based on the intended use scenario—for example, select pearl cotton for small pillows, molded foam or spray-adhesive cotton for sofa cushions, memory foam or hollow fiber cotton for office and car settings, and down or velvet pillows for bedroom headboards.
