TECHNICAL FIELD
[001] The embodiments herein generally relate to a mattress pad having multiple zones of comfort along its length. More specifically, the embodiments herein relate to a polyester fill mattress having distinct comfort zones, each particularly suited for supporting a particular portion of a human body.
BACKGROUND
[002] Mattresses pad have conventionally been constructed to provide extra cushion effect to the mattress. It also provides protection to the mattress. Conventionally the mattress pads are quilted evenly on the top to provide a flat surface. This type of mattress pad is largely homogeneous throughout, and there is no difference in structure in any particular area of the mattress.
[003] Conventionally the polyester filled mattress pad has three layers. The top and bottom layers are made up of fabric which may be manufactured using different textile materials including cotton, polyesters, silk, polypropylene or any other natural or manmade material while the middle layer is generally made up of polyester or cotton or blend of cotton polyester or goose feathers or blend of goose feathers, polyester, cotton or may include any other natural or manmade material. The middle layer is either blown filled (in case of lose fibers) or is manually/ mechanically placed (in case of garnet fill) in between the top and bottom layers. All these layers are sewn together on the edges and then all the three layers are quilted together. The quilt design includes geometric shape such as box, diamond, hexagon, etc. Finally a knitted or woven or non woven fabric is attached on the edges of the quilted piece to form the drop of the mattress pad. The purpose of drop is to make the mattress pad fit properly on the mattress. Yet the flat quilted surface of the mattress pad results in the lack of support at the various regions of the body which are required for better sleep and relaxation.
[004] The mass and distribution of a human body varies widely from head to toe, this places substantially more pressure on a mattress in areas such as the pelvic and shoulder regions than in other region. Over a period of time the structure of the mattress compresses noticeably to a greater extent in the pelvic and shoulder regions than the other areas of the mattress. Further, these compressed regions induce pain and aces in different regions of the human body. Usage of such mattress ultimately leads to discomfort in sleep and frequent tossing and turning on bed.
[005] As an alternative consumer’s usually purchase body contour mattress pad or mattress which are either made of memory foam or latex that are quite expensive. The body contour mattress pad helps in providing support to the entire body at the major areas but since these are made from latex or memory foam they are bulky, not so easy to handle and non washable. Further, they also heat up quickly during usage and often smell bad.
[006] Therefore, there is a need for a mattress pad having multiple comfort zones along its length. Further, there is also a need for the mattress pad having multiple comfort zones to support the human body and facilitate faster relaxation of the human body to induce better sleep. Furthermore, there exists a need for a mattress pad that can obviate aforementioned drawbacks.
OBJECT OF THE INVENTION
[007] The principle object of the embodiments herein is to provide a mattress pad having multiple comfort zones along its length.
[008] Still another object of the embodiments herein is to achieve multiple comfort zones on the mattress pad using wadding (fill material) and quilting patterns.
[009] Another object of the embodiments herein is to provide the mattress pad having multiple comfort zones to support the human body and facilitate faster relaxation of the human body to induce better sleep.
[0010] Yet another object of the embodiments herein is to increase sleep efficiency and provide higher level of restorative sleep.
[0011] These and other objects of the embodiments herein will be better appreciated and understood when considered in conjunction with the following description and the accompanying drawings. It should be understood, however, that the following descriptions, while indicating preferred embodiments and numerous specific details thereof, are given by way of illustration and not of limitation. Many changes and modifications may be made within the scope of the embodiments herein without departing from the spirit thereof, and the embodiments herein include all such modifications.
SUMMARY

Accordingly, the examples should not be construed as limiting the scope of the embodiments herein.
[0022] The embodiments herein achieve a mattress pad having multiple comfort zones along its length. The embodiments herein further provide the mattress pad having multiple comfort zones to support the human body at various regions and facilitate faster relaxation of the human body to induce better sleep. Referring now to the drawing, and more particularly to FIGS. 1 through FIG. 6, where similar reference characters denote corresponding features consistently throughout the figure, there are shown preferred embodiments.
[0023] FIGS. 1, 2 and 3 depict conventional mattress pad having a flat upper surface with box quilting, diamond quilting and invisible flat quilting respectively, according to an embodiment as disclosed. Conventionally the polyester filled mattress pad has three layers. The top and bottom layers are made up of fabric which may be manufactured using different textile materials including cotton, polyesters, silk, polypropylene or any other natural or manmade material while the middle layer is generally made up of polyester or cotton or blend of cotton polyester or goose feathers or blend of goose feathers, polyester, cotton or may include any other natural or manmade material. The middle layer is either blown filled (in case of lose fibers) or is manually/ mechanically placed (in case of garnet fill) in between the top and bottom layers. All these layers are sewn together on the edges and then all the three layers are quilted together. The quilt design includes geometric shape such as box, diamond, hexagon, etc. Finally a knitted or woven or non woven fabric is attached on the edges of the quilted piece to form the drop of the mattress pad. Yet the flat quilted surface of the mattress pad results in the lack of support at the various regions of the body which are required for better sleep and relaxation.
[0024] FIGS. 4A and 4B illustrate the ergonomic mattress pad with the differential wadding and quilting, according to an embodiment as disclosed. In one embodiment, the ergonomic mattress pad consists of an upper layer, a lower layer and a wadding layer disposed between the upper layer and the lower layer. The upper layer and the lower layer of the ergonomic mattress pad are made up of non woven /woven /knitted textile material which may be manufactured using different textile materials including cotton, polyesters, silk, polypropylene or any other natural or manmade material. While the wadding layer is made up of different fill weights. For example, loose fibers are filled in case of blown fill and garneted fibers are filled in case of manual/mechanical fill.
[0025] In an embodiment, all the three layers i.e. the upper layer, the lower layer and the wadding layer are quilted together to form one single non woven /woven /knitted textile material quilt cake. The quilted cake thus obtained is then attached with a knitted/ woven or non woven drop to complete the mattress pad. In one embodiment, the quilting is done in such a way that, it creates different wadding zones within the mattress pads having different elevations and quilting patterns. The mattress thus obtained has different support zones (elevated regions) which are achieved with the help of wading (filled material) of various densities (grams per square meters) and differential quilting.
[0026] In an embodiment, the wadding layer includes plurality of support zones namely, first wadding zone 101, a second wadding zone 103 and a third wadding zone 105. The first wadding zone 101 includes a predetermined thickness and length of wadding for supporting a head portion 107 and a neck portion 109 of said human body. However, it should be noted that the thickness and length of wadding can be varied based on the height and weight of the user (human). Further, the first wadding zone 101 includes a first quilt region 119 having a predetermined quilt pattern and a first non-quilt region 120. Also, it should be noted that the thickness, length and pattern of quilt can be varied based on the height and weight of the user.
[0027] In an embodiment, the second wadding zone 103 is provided with a predetermined thickness and length of wadding for supporting an upper body portion 111 and a lumbar portion 113 of said human body. However, it should be noted that the thickness and length of wadding can be varied based on the height and weight of the user (human). Further, the second wadding zone 103 includes a second quilt region 121 having a predetermined quilt pattern and a second non-quilt region 122. Also, it should be noted that the thickness, length and pattern of quilt can be varied based on the height and weight of the user.
[0028] In an embodiment, the third wadding zone 105 is provided with a predetermined thickness and length of wadding for supporting a lower back portion and a leg portion 117 of said human body, however, it should be noted that the thickness and length of wadding can be varied based on the height and weight of the user. Further, the third wadding zone 105 includes a third quilt region 123 having a predetermined quilt pattern and a fourth quilt region 125 having a predetermined quilt pattern. Also, it should be noted that the thickness, length and pattern of quilt can be varied based on the height and weight of the user.
[0029] The thickness of the wadding layer depends on the quantity of polyester fibres filled in the wadding. For example, the thickness wadding layer at the head portion 107 is within a range of 0.5 inch to 1 inch. The thickness at the neck portion 109 is within a range of 1 inch to 2 inches. The thickness at the lower back portion 115 is within a range of 2 inches to 5 inches. Further, the lengths of wadding layer at different zones can be varied. For example, the length at the head portion 107 is within a range of 6 inches to 10 inches. The length at the neck portion 109 is within a range of 6 inches to 8 inches. The length of upper body portion 111 is within a range of 8 inches to 14 inches. The length of the lumbar portion 113 is within a range of 10 inches to 15 inches. The length of the lower back portion 115 is within a range of 8 inches to 10 inches and the length of the leg portion 117 is within a range of 20 inches to 40 inches.
[0030] In one embodiment, the different comfort zones of the mattress pad are designed intelligently to provide maximum support to the human body, especially at the lumbar and the neck portions. These portions facilitates in relaxing the human body at a faster rate resulting in comfort and inducing better sleep. Thus it results in increased sleep efficiency and provides higher level of restorative sleep.
[0031] In one embodiment, based on the need of support the ergonomic mattress pad may be made of soft support or firm support by changing poly or poly blended material with a natural/ manmade fiber wadding.

Testing of the mattress pad in a Sleep lab
[0032] A clinical trial was done with the help of the conventional mattress pad and ergonomic mattress pad. Software and methodology used is as follows:
[0033] Qualitative and Quantitative EMG
[0034] Systems used: ALICE_5 and C2 I-330
[0035] Software used: Physiolab
[0036] Number of participants:10
[0037] Age:18 years to 50 years
[0038] Gender: 5 males and 5 females
[0039] Total time of recording per participant:30 minutes
[0040] Phases: 4, with pillow normal and test mattress, without pillow normal and test mattress.

Test procedure
[0041] Initially, multiple electrodes were introduced at different parts of the human body (subject), for example, three at the lower back, two at the neck portion and one at the hand of the subject. The electrodes are attached to skin of the subject using an adhesive. The subjects along with the electrodes were made to lie down flat on the regular mattress pad without pillow and a first EMG result was recorded. An electromyogram is used for evaluating and recording electrical activity produced in muscles of the human body. The subjects were then given a pillow while lying on the regular mattress pad and second EMG result was recorded. The subjects were then made to lie down on the test mattress pad (ergonomic mattress pad) without pillow and a third EMG result was recorded. The subjects were then given a pillow while lying on test mattress pad and a fourth EMG result was recorded. Ten subjects (humans) whose ages ranging between of 18 years to 50 years were considered for testing. Each subject was made to lie on the test mattress pad for 30 minutes. Test results were compiled to indicate the comparison between the conventional and test mattress pad. The table provided below indicates test results.

[0042] Test results as compiled indicate that with pillow on test mattress pad there is reduction of muscle tension in the lower back and the muscles are relaxed which helps in a better sleep quality.
[0043] FIG. 5 illustrates a graph showing the test results of EMG test conducted between the conventional mattress pad and the ergonomic mattress pad without using a pillow. FIG. 6 illustrates a graph showing the test results of EMG test conducted between the conventional mattress pad and the ergonomic mattress pad using a pillow. Both the graphs show a series of lines which are thicker and thinner at a given instant time interval. The thicker lines in the graph indicate that the muscle tension is high while the thinner line indicates that the muscle tension is low. The higher the muscle tension leads to a lower sleep efficiency. Thus from the above graphs, it can inferred that with pillow on test mattress pad there is reduction of muscle tension in the lower back and the muscles are relaxed which helps in a better sleep quality.
