In recent years, Sino is famous for its memory pillows, although latex pillows do not account for a high proportion of its business, but Sino does not use the Thai OEM model, the latex pillows in the Chinese market are produced in China, latex raw materials are imported from Thailand, and its natural latex content is about 85%, due to the mixture of a small amount of synthetic latex, there will be a slight smell when buying, and it needs to be placed in a cool and ventilated place for a few days to disperse the smell.
 
Among Sino's memory pillow products, the most recognizable is its 4D modeling patent, which is also applied to Sino latex pillow. The protruding part of the pillow fills the hanging position of the neck, which is suitable for sleeping on the back, and the concave part of the pillow can leave space for the shoulders, and the side sleep is more stable and fitting, and the cochlear design is increased at both ends of the pillow surface to relieve the pressure on the ears when sleeping on the side, and the double-layer pillow core design can also appropriately adjust the height of the pillow. Among the many templated latex pillows, 4D is not designed to be innovative in appearance, but indeed to improve the user's sleep needs from an engineering point of view.
 
The three basic latex pillows of Sino are Lexiang breathable model, Zhixiang massage model, and Yuexiang massage model, with a price of 300-400 yuan, and the height of the pillow is decent.
