CROSS-REFERENCE TO RELATED APPLICATIONS 
       [0001]    The present patent application is a continuation-in-part of, and claims the benefit of priority under 35 U.S.C. §120 to, U.S. patent application Ser. No. 29/567,827 filed Jun. 13, 2016, entitled “LIE-FLAT MATTRESS PAD”, the entirety of which is incorporated by reference. 
     
    
     BACKGROUND OF THE INVENTION 
       [0002]    Long-haul and international flights are a modern day necessity. Non-stop transoceanic and transcontinental flights often provide little opportunity for passengers to adventure beyond their assigned seats. Many airline seats may be adjusted to permit the passenger to partially recline, and some seats even permit the passenger to lie down completely horizontally. However, industrial airline seats are made to withstand thousands of hours of use and may not be ideal for passenger comfort while resting or sleeping. 
         [0003]    It would be advantageous to develop a multi-purpose lie-flat mattress pad for use in long-haul flights that improves passenger comfort. 
       SUMMARY OF THE INVENTION 
       [0004]    The invention is an improved mattress pad. The inventive mattress pad is made of multiple layers of fabric and fill to provide softness and air-flow to the user. Identical or different fabrics may be incorporated for the top and bottom of the mattress pad; the middle layer may be a single layer or may be symmetrically-configured or asymmetrically-configured component layers. It is a goal of the invention to provide a mattress pad that exhibits different air-flow characteristics to the user depending on the mattress pad orientation and therefore facilitate changes to the passenger&#39;s comfort and temperature. 
         [0005]    It is a goal of the invention to provide a mattress pad that can lie flat on a horizontal or inclined surface. It is a further goal of the invention to provide a mattress pad with a slip-resistant surface to reduce and prevent slipping of the mattress pad on horizontal or inclined surfaces. 
         [0006]    It is a goal of the invention to be lightweight and compact to save space on an airplane. It is a goal of the invention to serve multiple purposes including a mattress pad when placed flat and a pillow when rolled up or folded. In preferred embodiments the mattress pad includes a pocket so the pad may be secured within the pocket in a compact configuration for use as a pillow and for ease of transport. It is a goal of the invention for the mattress pad to be made of materials that are easily laundered. 
         [0007]    These and other features, aspects and advantages of the present invention will become better understood with reference to the following description and claims.

Preferably the intertwined thermoplastic filament or thread layer is between about 19.0 mm and about 25.5 mm. 
         [0026]    The mattress pad bottom layer comprises an air-permeable fabric. The bottom layer comprises at least one component layer. The bottom layer fabric may comprise natural or synthetic materials, or blends of natural and synthetic materials; the bottom layer fabric may comprise one or more of the following: cotton, silk, wool, rayon, wood cellulose, lyocell, linen, flax, hemp, jute, polyester, polyamide, nylon, polyvinyl chloride, polyethylene, polyethylene terephthalate, polyaramid, ethylene vinyl acetate, polyethylene vinyl acetate. In one embodiment the bottom layer comprises cotton fabric; in one embodiment the bottom layer is 100% cotton; in one embodiment the bottom layer comprises polyester fabric; in one embodiment the bottom layer is 100% polyester; in one embodiment the bottom layer is a cotton/polyester blend; in one embodiment the bottom layer is 60% cotton and 40% polyester by weight. In one embodiment the bottom layer comprises polyester fabric; preferably the bottom layer comprises polyester microfiber. In one embodiment the bottom layer comprises polyester mesh fabric. In a preferred embodiment the bottom layer comprises a fabric that is between 60 GSM and 110 GSM; preferably the bottom layer comprises an 85 GSM 100% polyester microfiber fabric. In one preferred embodiment, the bottom layer has a thread count between 160 and 200; in a preferred embodiment, the bottom layer has a thread count of 180. 
         [0027]    In a preferred embodiment the outside surface of the bottom layer is treated with a slip-resistant material to reduce or eliminate movement between the mattress pad and the airline seat or other surface upon which the mattress pad is laid. Patterns of a slip-resistant material such as lines, waves, dots, grids, or geometric shapes may be added to the outside surface of the bottom layer. The slip-resistant material increases friction between the mattress pad and the surface upon which it is placed, for example leather or plastic of an airline seat, and so movement of the mattress pad is resisted against the application of an exterior force. The slip-resistant material may be a polymer, such as vinyl, and more preferably an elastomer. The slip-resistant material may be applied to the bottom layer before the mattress pad layers are secured to form the final mattress pad or may be applied to the exterior surface of the bottom layer after the mattress pad layers have been secured together. The slip-resistant material may be applied by appropriate printing, spraying, painting, or screening methods. 
         [0028]    The top, middle, and bottom layers are secured together to form the mattress pad. In a preferred embodiment the layers are quilted together. Quilting is preferred as it creates pockets in the mattress pad for loft and air flow. Quilt stitches using straight lines or free motion may be used; examples of quilt stitches include parallel lines, horizontal lines, diagonal lines, curvilinear lines, crosshatch patterns, chevron design, onion design, geometric shapes, diamonds, triangles, squares, trapezoids, parallelograms, rectangles, hexagons, circles, ovals, spirals, zig-zags, repeating or non-repeating patterns thereof, or combination thereof. Preferably the layers are secured together with a chevron or diamond quilt stitch. 
         [0029]    Additional transverse stitching may be included in the mattress pad to facilitate, for example, laundry processing, packing, and/or storage. Lines may be quilt stitched across the width of the mattress pad to facilitate folding of the mattress pad. The mattress pad may have one or more than one transverse stitch line; the mattress pad may have 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 transverse stitch lines. Transverse stitch lines may be evenly distributed along the mattress length or may be at variable intervals. In one embodiment a single stitch line is positioned at the halfway point between the mattress pad top edge and bottom edge to facilitate folding the mattress pad in half; in one embodiment stitch lines are positioned at the ⅓ and ⅔ points between the mattress pad top edge and bottom edge to facilitate folding the mattress pad in thirds; in one embodiment stitch lines are positioned at the ¼, ½, and ¾ points between the mattress pad top edge and bottom edge to facilitate folding the mattress pad in quarters. In one embodiment stitch lines are positioned at intervals corresponding to the length of the pocket; in one embodiment where the pocket length is 20% of the length of the mattress pad, stitch lines are positioned at the 20%, 40%, 60%, and 80% points between the mattress pad top edge and bottom edge. Transverse stitch lines may be included in the mattress pad regardless of whether the mattress pad includes a pocket. The presence of transverse stitch lines does not adversely impact the rollability of the mattress pad. 
         [0030]    Optional fabric binding may be used around the perimeter of the mattress pad to secure the layers together. In one embodiment the fabric binding comprises the same material as the top layer; in one embodiment the fabric binding comprises the same material as the bottom layer. In a preferred embodiment binding comprises a fabric that is between 130 GSM and 210 GSM; preferably the fabric may be 130 GSM, 135 GSM, 140 GSM, 145 GSM, 150 GSM, 155 GSM, 155 GSM, 160 GSM, 165 GSM, 170 GSM, 175 GSM, 180 GSM, 185 GSM, 190 GSM, 195 GSM, 200 GSM, 205 GSM, or 210 GSM; preferably the binding comprises a 170 GSM polyester fabric. 
         [0031]    Preferred mattresses of the invention have a cotton top layer and a polyester microfiber bottom layer, however, cotton/polyester blends may be used. For example, a top layer may be made of a cotton and polyester blend having 60% cotton and 40% polyester by weight. In one embodiment, the top layer is made of a cotton/polyester blend where the warp comprises cotton yarns and the weft comprises polyester yarns. 
         [0032]    Optionally the mattress pad has a pocket at one end that is built into the outside surface of the bottom layer. The pocket is preferably made of a flexible mesh fabric that is open on one side. The mattress pad may be stored inside this pocket folding the mattress pad or by rolling it up from the opposite end then tucking the pad inside of the pocket; in one embodiment the mesh pocket may be pulled around the mattress pad to secure the pad within the pocket. With the optional pocket incorporated into the construction of the mattress pad, the need for a separate storage pouch or device is eliminated. The pocket width spans the width of the mattress pad; the pocket length is between about 10% and about 33% of the length of the mattress pad; more preferably the pocket length is between about 15% and about 20% of the length of the mattress pad. Preferably the pocket length is 10%, 11%, 12%, 13%, 14%, 15%, 16%, 17%, 18%, 19%, 20%, 21%, 22%, 23%, 24%, 25%, 26%, 27%, 28%, 29%, 30%, 31%, 32%, or 33% of the length of the mattress pad; in a preferred embodiment the pocket length is 16% of the length of the mattress pad. The pocket length may be adjusted based on the fabric of the pocket—a fabric having little potential for stretch may need to be a larger % of the length of the mattress pad compared with a fabric having a large potential for stretch. In one embodiment the pocket is made of a high-stretch material and has a length less than 16% of the length of the mattress pad; in one embodiment the pocket is made of a low-stretch material and has a length of more than 16% of the length of the mattress pad. 
         [0033]    When the mattress pad is rolled up and secured in the optional pocket, the product may be stored securely and easily for travel. The rolled-up mattress pad may be used as a pillow, for example, a neck roll pillow, a lumbar support pillow, or side support pillow. 
         [0034]    Mattress pad size may be chosen to accommodate specific surface sizes or user sizes. Preferred embodiments are sized to cover at least a portion of an airplane seat. Preferred embodiments have widths between about 380 mm and about 1140 mm, and lengths between about 1200 mm and about 2400 mm. One preferred embodiment has a width of about 500 mm and a length of about 1270 mm; another preferred embodiment has a width of about 610 mm and a length of about 1524 mm; another preferred embodiment has a width of about 1040 mm and a length of about 1960 mm. 
         [0035]    Mattress pad thickness is dependent upon the thickness of the component layers. The majority of mattress pad thickness will come from the cushioning middle layer. The thickness of the mattress pad is preferably between about 5 mm to about 80 mm; preferably the mattress pad thickness is about 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, 20 mm, 21 mm, 22 mm, 23 mm, 24 mm, 25 mm, 26 mm, 27 mm, 28 mm, 29 mm, 30 mm, 31 mm, 32 mm, 33 mm, 34 mm, 35 mm, 36 mm, 37 mm, 38 mm, 39 mm, 40 mm, 41 mm, 42 mm, 43 mm, 44 mm, 45 mm, 46 mm, 47 mm, 48 mm, 49 mm, 50 mm, 51 mm, 52 mm, 53 mm, 54 mm, 55 mm, 56 mm, 57 mm, 58 mm, 59 mm, 60 mm, 61 mm, 62 mm, 63 mm, 64 mm, 65 mm, 66 mm, 67 mm, 68 mm, 69 mm, 70 mm, 71 mm, 72 mm, 73 mm, 74 mm, 75 mm, 76 mm, 77 mm, 78 mm, 79 mm, or 80 mm. 
         [0036]    The mattress pad may be constructed so that the cross-section of the mattress pad appears to be the same whether oriented with the top layer facing upwards or downwards. Such “symmetrical” construction would provide the user with the same air flow characteristics regardless of whether the mattress pad is oriented with the top layer facing the user or with the bottom layer facing the user. Symmetrical construction also facilitates mattress pad construction by eliminating the need for unique order of materials from top layer through to bottom layer. In one embodiment of symmetrical construction, the top layer and bottom layer are made of the same fabric; in a preferred embodiment the top layer and bottom layer are comprised of 85 GSM polyester microfiber fabric with a thread count of 180. In one embodiment of symmetrical construction, the middle layer comprises a single layer (layer Z); in another embodiment of symmetrical construction the middle layer comprises an odd number of component layers (layer Y-layer Z-layer Y); in another embodiment of symmetrical construction the middle layer comprises an even number of component layers (layer Y-layer Z-layer Z-layer Y). In one embodiment of symmetrical construction the middle layer is a single layer of viscoelastic polyurethane foam (memory foam) having a density of 40 D with perforated holes; in one embodiment of symmetrical construction the middle layer is comprised of three component layers—a layer of viscoelastic polyurethane foam (memory foam) having a density of 40 D with perforated holes sandwiched between two layers each made of 190 GSM polyester bonded batting. 
         [0037]    In a preferred embodiment the mattress pad is constructed so that the cross-section of the mattress pad appears different whether oriented with the top layer facing upwards or downwards. This “asymmetrical” construction would provide the user with different air flow characteristics and comfort depending on whether the mattress pad is oriented with the top layer facing the user or with the bottom layer facing the user. Asymmetrical construction may be accomplished by (1) utilizing different materials for the top layer and bottom layer with symmetrically-configured middle layer; (2) utilizing different materials for the top layer and bottom layer with asymmetrically-configured middle layer; or (3) utilizing the same materials for the top layer and bottom layer with asymmetrically-configured middle layer. For asymmetric construction, if the top layer and bottom layer are made of the same material then the middle layer must be asymmetrically-configured. 
         [0038]    In one embodiment of asymmetrical construction, the top layer is different from the bottom layer, and the middle layer comprises a single layer (layer Z); in another embodiment of asymmetrical construction the top layer is different from the bottom layer, and the middle layer comprises an odd number of component layers (layer Y-layer Z-layer Y); in another embodiment of asymmetrical construction the top layer is different from the bottom layer and the middle layer comprises an even number of component layers (layer Y-layer Z-layer Z-layer Y). In one embodiment of asymmetrical construction the top layer is different from the bottom layer, and the middle layer comprises an odd number of component layers (layer X-layer Y-layer Z); in another embodiment of asymmetrical construction the top layer is different from the bottom layer and the middle layer comprises an even number of component layers (layer Y-layer Z-layer Y-layer Z). In one embodiment of asymmetrical construction the top layer is the same as the bottom layer, and the middle layer comprises an odd number of component layers (layer X-layer Y-layer Z); in another embodiment of asymmetrical construction the top layer is the same as the bottom layer and the middle layer comprises an even number of component layers (layer Y-layer Z-layer Y-layer Z). 
         [0039]    Preferred mattress pads of the invention have asymmetric construction. Preferred mattress pads utilize different fabrics for the top layer and bottom layer along with an asymmetrically-configured middle layer comprising at least two component layers; preferred mattress pads utilize different fabrics for the top layer and bottom layer along with an asymmetrically-configured middle layer comprising at least three component layers. Preferred mattress pads of the invention utilize different fabrics for the top layer and bottom layer along with an asymmetrically-configured middle layer comprising at least three component layers, one layer of which comprises viscoelastic polyurethane foam and one layer of which comprises polyester batting.

       EXAMPLES 
     Example 1 
       [0045]    The following example is meant to be illustrative and prophetic only. In this example a mattress pad is constructed of a top layer, a middle layer comprised of four component layers, and a bottom layer. 
         [0046]    The top layer comprises 200 GSM 100% polyester mesh fabric. 
         [0047]    The middle layer comprises (1) a first component layer made of 190 GSM polyester batting positioned adjacent to the mattress pad top layer and adjacent to (and above) the second component layer; (2) a second component layer made of 80 GSM polyester non-woven fabric positioned adjacent to (and below) the first component layer and adjacent to (and above) the third component layer; (3) a third component layer made of 6.5 mm thick memory foam having a density of 40 D with perforated holes positioned adjacent to (and below) the second component layer and adjacent to (and above) the fourth component layer; and (4) a fourth component layer made of 185 GSM siliconized polyester bonded batting positioned adjacent to (and below) the third component layer and adjacent to the mattress pad bottom layer. 
         [0048]    The bottom layer comprises 85 GSM 100% polyester microfiber fabric having a thread count of 180. The bottom layer further includes a repeating pattern of elastomeric dots on the outside surface as a slip-resistant backing. 
         [0049]    The layers are quilted together with a chevron quilt stitch. A 170 GSM polyester microfiber binding is used around the perimeter of the mattress pad to provide a 10 mm border. 
         [0050]    A stretch mesh tuck pocket is secured to the mattress pad at the top end of the bottom layer. The pocket is stitched on three sides—the top side, left side, and right side—so as to leave the bottom of the pocket open to receive the rolled-up mattress pad. The pocket spans the entire width of the mattress pad, and is about 16% of the length of the mattress pad. 
       Example 2 
       [0051]    The following example is meant to be illustrative and prophetic only. In this example a mattress pad is constructed of a top layer, a middle layer comprised of three component layers, and a bottom layer. 
         [0052]    The top layer comprises 200 GSM 100% polyester mesh fabric. 
         [0053]    The middle layer comprises (1) a first component layer made of 100 GSM polyester batting and positioned adjacent to the mattress pad top layer and adjacent to (and above) the second component layer; (2) a second component layer made of 6.5 mm thick memory foam having a density of 40 D with perforated holes positioned adjacent to (and below) the first component layer and adjacent to (and above) the third component layer; and (3) a third component layer made of 270 GSM polyester batting positioned adjacent to (and below) the second component layer and adjacent to the mattress pad bottom layer. 
         [0054]    The bottom layer comprises 85 GSM 100% polyester microfiber fabric having a thread count of 180. The bottom layer further includes a repeating pattern of elastomeric dots on the outside surface as a slip-resistant backing. 
         [0055]    The layers are quilted together with a chevron quilt stitch. A polyester microfiber binding is used around the perimeter of the mattress pad.
