With a comfortable bedroom and a Simmons, it is necessary to consider the bedding: the mattress or sleeper. A bed is just a place to rest, but lying on a naked Simmons without any mattress is like having a stage without any props, it is impossible to sing. Mattress has become an important tool to assist sleep. Modern people talking about the mattress will definitely think of three major pieces: pillows, sheets and quilts, which can be said to be the three major elements of bedding. We may want to analyze the role of these three elements. Pillow on the role of sleep can not be underestimated, “high pillow without worry”, “a pillow yellow beam” these idioms are related to the pillow. From ancient times to date, the raw materials used as pillows are endless and varied. For example, stone, bamboo, wood, fabric, etc., while its contents include cotton, cotton, mung bean bark, buckwheat bark, feathers, chemical fiber products and so on. The choice of pillow varies from person to person, and there are no strict rules. Most people are willing to use down pillows, because sleeping on them is soft, comfortable, durable and easy to wash, but people who are allergic to feathers can not use, otherwise it will cause an allergic reaction. Chemical fiber products pillow is also good, soft, comfortable, but unfortunately poor breathability, the head is prone to sweating people are not suitable, and long after use will become hard, not easy to expand. Pillowcase with cotton or chemical fiber products are available, but the pillowcase to cotton fabric is better. The height of the pillow depends on personal preference, but too high or too low pillow will cause excessive cervical bending, easy to appear “pillow”. Bed sheet to cotton is the best, taking its absorbent and easy to dye, but after washing to iron is its disadvantage. Chemical fiber products, if blended with cotton, is both absorbent and do not need to iron the advantages, more practical. There are many kinds of quilts, the most commonly used is cotton, but also available silk cotton, camel hair, down and so on. Down has the best warmth and is lighter, so it is more popular. In summer, towel quilts are often used, which are highly absorbent, comfortable and fluffy. Blankets are suitable for use in spring and autumn, but the weight is too heavy is a disadvantage, and they are often used as additions to quilts in China, not the main bedding category. As for bedspreads and so on, they are just decorative items and have little to do with sleep, so they will not be introduced. If you want to have a restful sleep, please pay attention to the texture, material and workmanship of the pillows, sheets and quilts.
