Down Filling
Down filling offers unparalleled softness and luxury, making it a top choice for those seeking plush comfort.
1. Pure Down (Goose Down/Duck Down)
- Features: Fluffiness ≥600 (used in high-end models).
- Advantages: Extremely soft, breathable, and can be fluffed back into shape.
- Disadvantages: Requires regular airing to prevent odor, and it is very expensive.
2. Down Cotton (Feather Silk Cotton)
- Features: Blend of down and fiber (down proportion ≤50%).
- Advantages: Cost-effective, close to down in feel and softness.

Down filling is ideal for those who prioritize softness and are willing to maintain the material’s fluffiness. It’s best used for those looking for a luxurious, comfortable sofa.
Fiber Filling
Fiber filling provides a budget-friendly, lightweight option with a range of options for varying firmness.
1. PP Cotton
- Features: Hollow polyester staple fiber, fluffy and soft.
- Advantages: Lightweight, low cost, and commonly used for temporary cushion fillings.

- Advantages: Environmentally friendly, mildew-proof, and great for cushion surfaces.
- Disadvantages: Weak support, often needs to be combined with foam for added support.
Fiber fillings are a great choice for temporary or softer cushions and provide a good balance of comfort and affordability.
Latex Filling
Latex offers exceptional durability and support, with both natural and synthetic variations available.
1. Natural Latex

- Springs and Foam Hybrid: Combines the comfort and resilience of foam with the support of springs.
- Spring-Coil Hybrid: Offers extra durability and a cushioned feel, perfect for those looking for a more traditional feel with added support.
Hybrid fillings are great for people who want the benefits of different materials, such as the softness of foam and the support of springs, creating a versatile, comfortable seating experience.
