How to choose the size of pillow case and pillow core

The size of pillow case is usually determined by the size of pillow core. Generally, the standard size of ordinary single pillow core is 45cm × 75cm. Since the pillow core will have a certain height, you need to add about 10cm in length and width respectively on the basis of the size of the pillow core when purchasing pillow cases. For example, 45 × The size of 75cm pillow core matched with pillow case should be 55 × About 85cm.
Choice of pillow:
1. Suitable: The best pillow should be able to support the natural bending of the cervical spine and keep the cervical spine straight.
2. Height selection: The height of the pillow is not a matter of ease or the lower the better. 8-10 cm is appropriate. For those who prefer to sleep on their back, the pillow height should be 8 cm. For those who prefer to sleep on their side, the pillow height should be 10 cm.
3. Fillers in the pillow: The fillers in the pillow must be elastic and have a certain supporting force, such as buckwheat pillow and latex pillow.
4. Shape: The real name of the pillow should be "pillow neck", because we don't use it to pillow our head, but to pillow the empty part of our neck. When we sleep, we usually make the pillow into a yuan bao shape with the middle low and the sides high, and put the head in the middle depression.
Type of pillow:
1. Down pillow
The down pillow is just like the down quilt. It is light, fluffy, breathable and warm. It can support the head, shoulders and neck, and can bring good sleep experience. At the same time, because the softness of down itself is very awesome, it will not collapse, sag and other deformation phenomena after long-term use. However, the price of down pillows is generally not very low. In addition, it is difficult to clean them because they cannot be washed.
2. Natural pillow
There are only two kinds of mainstream fillers for natural pillows: buckwheat peel and cassia seed. This type of pillow is more comfortable to sleep, and the filler can adapt to the shape and position of the head, with a high degree of fit. However, natural pillows should be used in a dry environment, otherwise they are susceptible to moisture and mildew. They can be regularly placed in the sun to expose to the sun to achieve the purpose of cleaning and disinfection.
3. Memory pillow
The memory pillow is mostly made of polyurethane, which has the advantages of slow rebound and strong support, supporting the head and relaxing the shoulder and neck to some extent. Memory pillow can be said to be a popular pillow type in recent years, but we should pay attention to avoid products with poor quality when purchasing.
4. Latex pillow
Latex pillow can be said to be a popular product in recent years. It has good support, breathability and comfort, and can fit the head and neck curve to the greatest extent, so as to improve the sleep quality. Of course, these are preconditions: the real natural latex pillow is purchased. The market for latex pillows is mixed. Many businesses sell "fake latex pillows" under the brand of natural latex, so they need to polish their eyes when purchasing.
