FIELD OF TECHNOLOGY

[0001] The present invention relates to the field of sleep improvement technology, including, but not limited to the use of such technology in the hospitality industry. Specifically, the invention relates to a sleep system including a set of textile products that, based on their composition, construction, and relative positioning with one other, can improve the quality and comfort of the sleep environment, including over an extended period of time. The invention further relates to a sleep system that can be incorporated with existing mattresses and/or decorative bedding.

Additionally, the invention includes methods of improving the sleep environment using the inventive sleep system.

BACKGROUND

[0002] Scientists have observed that many critical functions take place during sleep. During deep sleep, the body repairs muscles and tissues as well as cellular damage, releases growth hormones, reduces blood pressure and thus cardiovascular work, boosts the immune system, and replenishes energy reserves. During REM sleep, the brain processes, stores, and organizes information, assisting in memory and learning. Long periods of sleep are needed to obtain sufficient deep sleep and REM sleep to maintain such functions.

[0003] Significant research has been undertaken to identify which conditions are necessary to both fall asleep and remain asleep. The conditions associated with the“sleep chamber” in particular have been studied at length. The“sleep chamber” is the space formed between the sheet that is placed on top of the mattress/mattress topper (hereinafter a“fitted sheet”) and the flat sheet that covers a person when they are lying in bed. Both the layers of bedding below and above the sleep chamber affect the conditions within the chamber and impact the quality and comfort of sleep. While a person is at rest, the heat and water vapor emitted from the human body significantly increase the temperature and relative humidity of the sleep chamber over time.

[0004] Ideally, conditions in the sleep chamber would keep the temperature at or below human body temperature and maintain a relative humidity of 65% or less throughout the sleep period. Unfortunately, most bedding does not allow for air breathability and permeability and fails to absorb water vapor adequately. Over time, this creates a sleep chamber that is hoi, humid, and not conducive to restful sleep.

[0005] To solve the heat and humidity issues of the sleep chamber, many suggest using a new mattress that contains cooling materials and components and/or is made using construction methods that assist with air flow . Replacing a mattress, however, is a significant expense and creates mattress-related environmental waste, some of which may be toxic, particularly for memory foams. For hotels and other hospitality locations, mattress replacement may not be suitable for these reasons as well as other reasons. In particular, most hotels have an eight to ten year replacement cycle for mattresses— since the quality, composition, and functionality of the mattresses can vary greatly with age, it may be difficult to determine which mattresses should be replaced. Additionally, in the hospitality industry, it is common to use mattress encasements that completely cover the mattress with near air-tight materials that encumber any air-flow and cooling technology that the mattress may have been designed to create. These encasements eliminate any moisture absorption which is a critical component of maintaining an optimal sleep environment within the sleep chamber.

[0006] There is a need for a sleep system that improves the comfort and quality of the sleep environment by maintaining optimal temperature and humidity conditions inside the sleep chamber. There further is a need for a sleep system that does not require the replacement of the mattress to reach the goal temperature and humidity conditions inside the sleep chamber. There also is a need for a sleep system that provides a consistent level of comfort and quality of the sleep environment regardless of the underlying mattress.
