Mattress spring refers to a type of spring used for internal support of a mattress, also known as a mattress spring rectangular machine. Mattress springs are generally made by bending and forming steel wires, and are mainly divided into two types: spiral springs and rectangular springs.
    Spiral spring is a common type of mattress spring, which is formed by bending steel wire into a spiral shape and used for internal support and pressure relief of the mattress. Spiral springs are generally thicker and have a diameter between 2-5 millimeters. The number and strength of spiral springs used on different mattresses also vary.
    Rectangular spring is another type of mattress spring, which is made of steel wire that has been bent and formed multiple times, presenting a rectangular shape. It is usually used for supporting high-end mattresses and can provide better support and comfort. The thickness and elasticity of rectangular springs can also be adjusted according to different needs.
    Mattress springs are usually made of high-strength, corrosion-resistant steel wire materials to ensure their strength and durability. In the production of mattresses, the number and arrangement of springs can affect the quality and comfort of mattresses. Therefore, manufacturers usually optimize design and production based on different market demands.
