Quality maintenance of pillows

Most of the common pillows on the market are filled with ordinary sponge, memory foam, cotton, etc. This type of pillow is easy to deform after being used for a long time, and its elasticity also deteriorates, which cannot support the normal physiological bending of the human body. Usually you can try to fold the pillow in half, and then let go. If the pillow snaps back to its original shape immediately, and the pillow core has no obvious crease, it means that it is in good condition. If it rebounds slowly or easily leaves creases, it means that the elasticity has deteriorated, and it cannot even provide enough support for the head and neck, which will affect sleep and bone health, causing insomnia, stiff neck, cervical spondylosis, etc. .
