With real wood plywood for frame materials such as metals, plastic foam with spring bandage as elastic filler material, such as surface with skin furniture made of fabrics such as cloth coated, characterized by contact with human body parts made of software materials or finishes by soft materials.
the definition of A furniture, soft pot: 1, the definition of sofa: A. Special: a spring loaded soft mat base chairs. B。 Generalized: people who are equipped with soft mat or fitted with soft contact city lie on the surface of the appliance. C。 Center: the software composition of soft mat is not necessarily the spring 2, mattresses, mattress is to ensure that consumers get healthy and comfortable sleep and use a between human body and bed, mattress material is various, different materials of mattress sleep can bring different effect. Second, the classification of soft furniture: modelling points: 1, according to the specifications single, simple and easy, many people, multi-function. 2, according to the feature points: ordinary, sofa bed, combination, intelligent massage. 3, according to the style points: American, European, Japanese and Chinese, the classification of the mattress: spring soft, filling water, air, foam latex, palm, magnetic, electric, intelligent massage. Three, soft furniture main materials: 1, wood and man-made board, metal, the main structure and basic model satisfies the requirement of modelling of sofa and strength requirements. 2, all soft sofa stents: hardness 3, part of the exposed parts: appropriate wood grain is beautiful, material is qualitative good, hardness is larger. 4, a multilayer: 9, 12, 15, 18 mm. 5, fiber board: less than 0. 4 g/cm3, medium density 0. 4 - 0. 8, 0. 8 - 0. 9. 6, metal: high strength, good elasticity, resilient, weldable calcined casting can be bent into different shapes, create all kinds of style. 7, spring: offer good elasticity, and after the pressure to withdraw, can make the soft furniture surface efface, soft furniture gives a person the degree of comfortable, how much does not depend on the number of spring, and relies on the quality of spring design. 8, plastic foam, a kind of full of gas, has sealing side loose pore structure ( Hole wall without feeling) Or even the hole loose pore structure ( The cavity is same) The lightweight plastic. Soft furniture is mainly on the soft polyurethane foam plastic, commonly known as sponge, specifications and more flexibility is good, cover on spring, craft is simpler, but the density of not less than 25 kg/m3, other parts also should be more than 22 kg/m3. 9, sponge: regular, high rebound, hole sponge. 10, foam rubber, latex after foaming treatment of elastic white foam objects; Thicker foam rubber as the weight is made in the cylindrical concave hole, the price is more expensive, commonly used in high-grade soft furniture. Four, sofa design principles: 1, sofa characteristics: comfortable, robustness and durability. 2, the structure of the sofa style: the size of the sofa structure proportion, length, size, etc. 3, stability and a sense of security: object stable rule: low center, large bottom area 4, : common symmetric form: mirror, shaft, rotary 5, seated in the main points: the legs, hips and back. 6, the Angle: the back of a chair and the Angle between the horizontal plane and sit face and horizontal plane, greater than 110 to increase support for head and neck. 7, high: foot to knee length depends on the human body. 8, seat width: determine human hips. Before and after 9, sit deep: the depth size, according to average human thigh length is 445 mm. 10, armrest height: arm surface to the vertical distance. 11, high back: human upper body namely the femur to cervical average scale.
