Lianrou Mattress machinery uses a special structure of ultrasonic technology for welding, 100% without the use of hot melt adhesives or other glue for bonding. Moreover, the firmness of the ultrasonic welding technology's seams is much higher than that of hot melt adhesive bonding, which is environmentally friendly and healthy, meeting the environmental protection standards of the United States, Japan, and Europe. It is suitable for mattress manufacturers to create high-end, environmentally friendly, glue-free mattresses and detachable mattresses.

2. High comfort

Compared with other springs, box springs are softer and more flexible, featuring high breathability, high resilience, and resistance to deformation. They can provide better comfort in mattresses and are often used as the comfort layer in high-end mattresses.

3. Good support

As a filling material, the support of box springs is better than that of sponge and latex. It can flexibly extend and contract according to the human body's curves and weight, evenly support all parts of the body, keep the spine naturally straight, relax and stretch the muscles, and reduce the number of times one turns over during sleep. Mattresses that use box springs are usually paired with other springs to form a double-spring support system, further enhancing the quality of the sleep experience.

Common double-spring support systems, such as independent pocket springs + box springs. Each spring tube of the independent bagged spring can extend and retract independently. The springs do not affect each other and have strong anti-interference ability, which can create a comfortable and quiet deep sleep experience. The box spring is highly sensitive to force and can respond quickly to the slightest movements of the body, capturing the subtle sleep movements to keep the spine healthy and relaxed. At the same time, each spring supports independently, precisely adjusting the mattress's support level, protecting the waist and spine, and providing a quiet and comfortable sleep. Therefore, some baby mattresses use box springs to better support the baby's body and care for the baby's growth and development.
