Caterpillar Sofa Cushion is a modular sofa cushion that is derived from the Japanese tatami concept and is designed to meet the diverse needs of modern living spaces. Its core structure is made of high-density polyether foam and polyester cotton, providing balanced support and comfort. The external covering material is mostly high-quality technical suede, which has good breathability and wear resistance. In addition, some products are equipped with adjustable backrests and non-slip bases to improve stability in use. Due to the modular design, users can combine them according to space layout and personal preferences to meet personalized needs.
Features
Contour structure fits the curve
Caterpillar Sofa Cushion adopts a multi-segment arc contour design, with an overall segmented structure that conforms to the natural curves of the human back, waist and legs, with a larger support area and contact points that disperse pressure. Under the equivalent support area, this structure can increase the contact area by about 18% compared to traditional flat cushions, thereby effectively reducing unit pressure, alleviating the force on the spine, and reducing muscle fatigue caused by long-term sitting and lying. This design is suitable for situations where the back and waist need to be supported for a long time.
High-resilience foam filling
The product is filled with high-resilience foam with a density of 45D. The foam rebound rate exceeds 60%, which is about 40% higher than the recovery capacity of ordinary 35D sponge after compression. This value means that the foam can recover its original shape faster under short-term and continuous pressure, reducing collapse and deformation, and is suitable for long-term use. After 30,000 cycles of pressure testing, the thickness loss rate of high-density materials is less than 5%, maintaining structural integrity and ensuring that users still have stable support after long-term use.
The outer layer fabric is soft and wear-resistant
The outer layer of Caterpillar Sofa Cushion is made of short-fiber polyester blended fabric, with a breaking strength of more than 350N. After 15,000 times of wear resistance testing by Martindale, there is no obvious pilling or fiber breakage on the surface. This type of fabric has a tight structure and a yarn density of more than 200T. Its tear resistance and durability are suitable for daily household use. The surface of the fabric feels soft and has low friction, which is suitable for use in direct contact with the skin, while taking into account durability and comfort.
