AI Technical Summary

Technical Problem

Traditional sofas use down or foam filling materials, which result in poor breathability. They are prone to moisture and stuffiness after long-term use. The uneven filling material causes the sofa surface to sag and deform, making it unable to effectively release pressure, affecting user comfort and health.

Method used

Elastic honeycomb panels are used as the skeleton filler, and airflow channels are formed through drainage tubes extending between the contact surface and the skeleton connection surface. Combined with the compression deformation curve of the thermoplastic material, the pressure is evenly distributed, and the skeleton filler is stabilized by the connection structure. The design is ergonomic and streamlined.

Benefits of technology

It improves the air permeability and comfort of the sofa, evenly distributes pressure, reduces fatigue caused by sitting for a long time, avoids filling displacement and deformation, and extends service life.
