If you feel the need , but also can buy, but the long-term sleep air bed not only the body's normal state is not good bones , but also because air bed gas barrier property , the pad bedding gathered a large amount of water vapor, so that will make people sleep humidity environment is too large , not only for sleeping & ldquo; comfort & rdquo; has a great impact , but also people are likely to suffer from bone and joint rheumatism class , so I do not advocate long-term use of air bed .
