The following specification particularly describes the invention and the manner in which it is to be performed:

POSTURE SUPPORT MATTRESS
TECHNICAL FIELD
The present subject matter generally relates to a mattress, and more particularly, relates to a posture support mattress.
BACKGROUND
People nowadays are paying more and more attention to physical and mental health. One of the most important elements in assuring physical and mental health is the quality of sleep. The quality of sleep includes various factors, out of which sleeping posture is one of the most important factors. A lot of people face back aches and discomfort due to incorrect posture during sleep.
Body needs support in two ways when we sleep. The first and foremost is the support to the spine. The spine needs to be in the natural shape during sleep for a healthy spine. The mattress should provide enough support to the muscles when we toss and turn to avoid the stress on the spine.
Second aspect of support is to avoid pressure point generation. Pressure points are locations on the body where an individual feels discomfort while lying down. It occurs when the weight of the body is pressed against a firm surface. The soft tissues get pinched between the mattress and bone, which restricts blood flow. Sleeping on such a mattress can result in pressure point discomfort forcing a person to toss and turn more frequently than usual resulting in a night full of disturbed sleep, a morning awakening of aches and pains, and a tired feeling the entire day.
There are different sleep positions in which people sleep of which two types are very common, i.e. sleeping on back and sleeping on side. Both these sleeping postures conditions/postures need to be supported differently to give adequate support

to the spine to retain its natural shape and to avoid stress being developed in the contact points. The need of providing different firmness to support the different parts of the body is a known fact and this has been already been attempted by the major mattress makers across the world. They are generally called 3 zone mattresses, 5 zone mattresses and 7 zone mattresses. Further, people have different preferences for the "feel" of a mattress, varying from very firm to very soft. These preferences may differ from the level of support that would provide the best sleep posture. An occupant sitting in a bed would require a different softness or firmness for comfort and correct support than an occupant lying prone or on one side. In addition, the correct firmness would vary depending upon the particular occupant using the bed. None of the existing mattresses are made with a view of catering to a particular occupant.
Hence, there is a need for a mattress which can help in getting a comfortable sleep, provides correct posture during the sleep and overcomes the aforementioned and other challenges related to sleeping posture.

DETAILED DESCRIPTION
The embodiments of the present subject matter are described in detail with reference to the accompanying drawings. However, the present subject matter is not

limited to these embodiments which are only provided to explain more clearly the present subject matter to the ordinarily skilled in the art of the present disclosure. In the accompanying drawings, like reference numerals are used to indicate like components.
Described herein is a posture support mattress, designed to support the posture of the body while we are asleep. Body needs support in two ways when we sleep. The first and foremost is the support to the spine. The spine needs to be in the natural shape when we sleep for the better health of spine. The mattress should also provide enough support to the muscles when we toss and turn to avoid the stress on the spine. Second aspect of support is to avoid pressure point generation. Pressure points are locations on the body where an individual feels discomfort while lying down. It occurs when the weight of the body is pressed against a firm surface. The soft tissues get pinched between the mattress and bone, which restricts blood flow. Sleeping on the wrong mattress can result in pressure point discomfort forcing you to toss and turn more frequently than usual resulting in a night full of disturbed sleep, a morning awakening of aches and pains, and a day feeling tired and not at your best.
There are different sleep positions in which people sleep of which two types are very common. They are sleeping on back and sleeping on side. Both these conditions need to be supported differently to give adequate support to the spine to retain its natural shape and to avoid stress being developed in the contact points.
The posture support mattress disclosed in the present subject matter has been described facilitating both the positions of sleep (sleeping on back and sleeping on side). Further, the posture support mattress is able to support the weight of the person sleeping on it.
The posture support mattress in accordance with the present subject matter takes into consideration, weight of the person while developing the mattress. The

firmness of the material used in present posture support apparatus is designed based on the weight of the occupant for providing adequate support to the body posture of the occupant in order to deliver comfortable and disturbance-free sleep.
FIGURE 1 illustrates a perspective view of a posture support mattress 100 comprising top two layers configured to support an occupant’s body when the occupant sleeps on the back in accordance with an embodiment of the present subject matter. In an embodiment, total thickness of the top two layers is 50 mm.
FIGURE 2 illustrates a perspective view of a posture support mattress 100 comprising a core layer configured to support occupant’s body when the occupant sleeps on the side in accordance with an embodiment of the present subject matter. Different zones of occupant’s body are shown in said figure, that is, a) head and neck, b) shoulder/chest and back, c) lumbar, d) pelvic and e) legs.
FIGURE 3 illustrates an exploded view of a posture support mattress 100 in accordance with an embodiment of the present subject matter. As shown in FIGURE 1, top two layers comprise a total thickness of 50 mm and are designed to support the occupant’s body when the occupant sleeps on the back. The top layers comprise a first top layer 102 and a second top layer 104.
The first top layer 102 and the second top layer 104 can be made up of a plurality of foam grades in different embodiments. For example, the first top layer 102 and the second top layer 104 can be a combination of super soft and firm foam. Further, in another embodiment, the first top layer 102 and the second top layer 104 is a combination of super soft foam and memory foam. However, it is to be understood that the above top layers’ foam grades are exemplary and not limiting in any way. Further, it is clear to person skilled in the art that any similar foam type known in the art can be used to form aforementioned top layers.

The first top layer 102 is super soft foam for cushioning while sleeping on back. The second top layer 104 is comparatively firmer foam for providing support while sleeping on back. The types of foam used to construct the first top layer 102 and the second top layer 104 are chosen based on the firmness/softness required to provide enough contouring along the natural shape of the body while the user sleeps on back. The softness or firmness of the first top layer 102 and the second top layer 104 required for said function vary based on the weight of the person sleeping. If the type of memory foam is chosen without focusing on the body weight, a light weight person may feel the posture support mattress 100 as too hard and a heavy weight person may feel the posture support mattress 100 too soft. Thus, the memory foam material is selected after conducting multiple trials with people of varying weight. It is not logical to arrive one material specification which is good for both light weight persons and heavy weight persons.
In an embodiment, the users/persons are categorized into following three categories:
• Light weight body - 30 to 60 Kg
• Medium weight body - 50 to 90 Kg
• Heavy weight body - 80 to 110 Kg
Thus, the posture support mattress 100 is designed into three different variants for the aforementioned weight categories with material suiting to support a light weight person, medium weight person and heavy weight person respectively. The materials combination and construction is configured to confirm to the firmness required for three predefined weight categories. However, the above broad weight categories are just exemplary and the present subject matter is not limited to the above

three weight categories and relates to customized posture support mattress having different combinations of material for different persons.
Further, the posture support mattress 100 comprises a core 106 designed in segments with materials of different firmness to support the occupant’s body shape when the occupant sleeps sideways. While standing, the entire weight of the human body is excreted downward, but while sleeping the weight is excreted downward in a distributed way. There are 5 major points of contact through which the weight is excreted downward. These are the points where pressure point gets generated, if the support of the mattress is more than required. Pressure points are locations on the body where an individual feels discomfort while lying down. It occurs when the weight of the body is pressed against a firm surface. The soft tissues get pinched between the firm surface and bones, which restricts blood flow. The 5 major points are head, shoulder, lumbar, pelvic and leg. Further, sleeping on a wrong mattress can result in pressure point discomfort, forcing a person to toss and turn more frequently than usual resulting in a night of disturbed sleep due to tossing and turning, a morning awakening of aches and pains, and a day feeling tired. The posture support mattress 100 takes into account the weight and body type of a user and maintain uniform pressure distribution to avoid pressure point generation.
Figure 4 illustrates average weight distribution through different zones of human body calculated from average body segment data. There are 5 different zones namely zone 1 (120) - head and neck, zone 2 (122) - chest and back, zone 3 (124) -lumbar, zone 4 (126) - pelvic and zone 5 (128) - legs. The zone 1 constitutes 8.23 %, zone 2 constitutes 24.71 %, zone 3 constitutes 16.1 %, zone 4 constitutes 38.21 % and zone 5 constitutes 12.86 % of the body weight.

Thus, to provide the appropriate support and prevent the creation of pressure points onto different zones of the body, the core 106 is positioned below the second top layer 104. While a user sleeps on his side, the natural shape of the body requires a contouring which goes beyond the first and second top layers 102, 104 to support the spine alignment and avoid pressure point generation. Here, because of the human body structure, the shoulder area and hip area need more penetration and rest of body parts needs support in reverse direction. Hence, the core 106 comprises different segments using materials with different firmness or softness. The core 106 includes a first core segment 108, a second core segment 110, a third core segment 112, a fourth core segment 114 and a fifth core segment 116. When a user sleeps on his side, the first core segment 108 supports the head portion, the second core segment 110 supports the shoulder, the third core segment 112 supports the lumbar portion, the fourth core segment 114 supports hip portion and the fifth core segment 116 supports the legs. The aforesaid configuration is based on multiples trials and experiments with different people having different body weights and types. Further, the posture support mattress 100 comprises a bottom layer 118 positioned below the core 106. The bottom layer 118 is positioned to provide support to the entire structure of the posture support mattress 110 lying on said bottom layer 118 and is made of highly durable material.
In an embodiment, the first core segment 108, the third core segment 112 and the fifth core segment 116 are made of foam. Further, the second core segment 110 and fourth core segment 114 comprise soft springs. The bottom layer 118 is made of hard polymers or hard foam to act as the holding structure and for longer durability. Moreover, similar to the first and second top layers 102, 104, the core 106 is also comprises 3 variations suiting to support three broad different weight categories.

However, it is evident to a person skilled in the art that the type of materials used to manufacture the posture support mattress 100 is indicative and not limiting. Further, any suitable materials known in the art which can show the aforementioned properties can be used to manufacture different layers and segment of the posture support mattress. Also, the above broad weight categories are just exemplary and the present subject matter is not limited to the above three weight categories and relates to customized posture support mattress having different combinations of material for different persons.
Although the invention has been described with reference to specific embodiments, this description is not meant to be construed in a limiting sense. Various modifications of the disclosed embodiments, as well as alternate embodiments of the invention, will become apparent to persons skilled in the art upon reference to the description of the invention. It is therefore contemplated that such modifications can be made without departing from the spirit or scope of the present invention as defined.
