Description

RELATED APPLICATION INFORMATION

This application claims the benefit of U.S. Provisional Application 62/317,541, filed Apr. 2, 2016, which is hereby incorporated by reference.

TECHNICAL FIELD

The present disclosure relates generally to bed mattresses. More particularly, the present disclosure relates to foam bed mattresses having a plurality of slots into which a stiffening member can be inserted for the purpose of adjusting firmness.

BACKGROUND

Sleep plays an important role in a person's overall health and enjoyment of life. The quality and quantity of sleep affects the body's ability to function normally and the ability to reach peak performance. Physiologically, sleep affects brain activity, heart rate, blood flow to the brain, sexual arousal, and body temperature. Sleep deprivation shows a strong correlation to obesity, diabetes, stroke, depression, and hypertension. Restful sleep is dependent upon the level of comfort while lying prone. Concentration of pressure on certain parts of the body and/or poor skeletal alignment are been linked to restless sleep. Sleeping on a mattress or other support surface that does not properly support and conform to the shape of the body or to the spine's natural curves can significantly contribute to restlessness or inability to sleep.

Traditionally sleep systems incorporate a mattress consisting of an outer layer of fabric and padding, surrounded by a series of spring coils. The fabric is stretched tightly across the padding to hold them in place, which in many eases creates a surface that is too hard. The mattress is usually supported by a flexible box spring, thereby enabling the mattress to compress where needed. However, the stiffness of the box springs can cause It to push back against the mattress in areas of greatest compression.

More recently, foam mattresses have been developed to provide adequate support without the use of spring coils. Current foam technology can be categorized according to load bearing capacity by time and temperature variables. A standard measure of Indentation Load Deflection (ILD) or Indentation Force Deflection (IFD) is a scaled range measurement of the load bearing capacity and deformation properties of flexible foam, measured as a force required to compress the sample to a fixed percentage of the sample initial height pursuant to ASTM D3574. Rates of recovery and thermal response rates of foam samples are also measured.

Although conventional foam mattresses provide the advantage of shape conformity and thermal responsiveness, structural support is sacrificed, particularly in areas of highest load concentrations. Although changing the stiffness of a foam mattress can alleviate this problem to some degree, the optimal stiffness should be different depending on body type and weight. U.S. Bedding manufacturers tend to ignore body types and weight, and market sleep systems constructed under an inaccurate assumption that 95% of the population has the same body type.

Accordingly, what is needed in the industry is an improved mattress that can be selectively optimized to provide the desired structural support for an individual's body type and weight. Moreover, what is needed in the industry is a bedding system in which the firmness can be adjusted repeatedly, and without a significant increase In manufacturing cost.

DETAILED DESCRIPTION

Referring to FIGS. 1 and 2, a mattress system 100 is depicted in accordance with an embodiment of the disclosure. Mattress, system 100 can include a mattress 102 and one or more rigid plates 104. In one embodiment, the mattress 102 can be constructed of foam and can conform to standard mattress dimensions. For example, the mattress 102 can measure approximately: 39 inches wide by 74 inches long (twin), 39 inches wide by 80 inches long (twin extra long), 54 inches wide by 74 inches long (full), 60 inches wide by 80 inches long (queen), 76 inches wide by 80 inches long (king), and 72 inches wide by 84 inches long (California king).

The mattress 102 can include a plurality of stacked layers 106A-F. In one embodiment, there are six stacked layers 106. In other embodiments, there may be any number of stacked layers 106. Each of the plurality of stacked layers 106 can include atop surface 108 and a bottom surface 110. A plurality of interstitial pockets 112 can be defined by the respective top surfaces 108 and bottom surfaces 110 of adjacent stacked layers 106. In one embodiment, the plurality of stacked layers 106 are fused together at least at one of the head of the bed 114, the foot of the bed 116, the lateral center of the bed 118, or a combination thereof. For example, in one embodiment the mattress 102 is constructed as a unitary foam member, and the plurality of interstitial pockets 112 are cut into the side of the mattress 102, thereby forming the plurality of stacked layers 106.

In one embodiment, the mattress 102 can include a covering 120 configured to protect the plurality of stacked foam layers 106. In some embodiments, the covering 120 can include a seam (not depicted) along one edge configured to selectively enable access to the plurality of interstitial pockets 112. The seam can be scalable, for example by a series of buttons or snaps, a zipper, hook and loop fasteners, or other conventional fabric-fasteners.

The rigid plate 104 can be configured to be inserted into one of the interstitial pockets 112. The rigid plate 104 can be constructed of a rigid material, such as wood, plastic, hard foam rubber, or other conventional material with an element of rigidity. The rigid plate 104 can include one or more handles 122, configured to enable a user to more easily grip and manipulate the rigid plate 104.

In some embodiments, the rigid plate 104 is shaped and sized to fit within an interstitial pocket 112. In one embodiment, the rigid plate 104 has a shape to approximate a standard mattress size, or a half standard mattress size, with a reduction in size to accommodate where portions of the stacked layers 106 are fused together at least at one of the head of the bed 114 the foot of the bed 116, the center of the bed 118, or a combination thereof. For example, in one embodiment, the rigid plate 104 has a width of between 30-39 inches and a length of between 65-75 inches.

Referring to FIG. 3, a rigid plate 104 having a plurality of hinge sections 128 is depicted in accordance with an embodiment of the disclosure. In one embodiment, the hinge sections 128 can be living hinges. For example, in one embodiment, rigid plate 124 can be constructed of a unitary sheet having a plurality of thicknesses, wherein portions of greater thickness represent the rigid members 126 and portions of lesser thickness represent the living hinge sections 128. In another embodiment, the plurality of rigid members 126 are contained in a fabric housing, wherein the fabric housing between the rigid members 126 represents the hinge sections 128.

Hinge sections 128 can enable a user to more easily move the rigid plate, as the hinge sections can flex, particularly when going around corners within the confines of a user's residence. Hinge sections 128 can also enable a user to told portions of the rigid plate 124 over on itself, thereby doubling or tripling the thickness of the rigid plate 124 over certain portions of overlap. Such portions of overlap may be desirable in cases where greater support and additional mattress firmness are desired. For example, a user may prefer additional support under their head and/or feet, and therefore may fold a portion of rigid plate 124 over on itself in order to double its thickness prior to insertion into the interstitial pocket 112. In another example, a user may prefer additional support under their lower back, and may fold a portion of the rigid plate 124 over on itself twice in order to triple its thickness prior to insertion into the interstitial pocket 112.

Referring to FIGS. 4 and 5, a mattress system 100 including two rigid plates 104 is depicted in accordance with an embodiment of the disclosure. In some embodiments, the length of the rigid plate 104 can be substantially less than the length of the interstitial pocket 112. for example, in some embodiments, the length of the rigid plate 304 can be between 6-12 inches, between 12-36 inches, or any length that fits within interstitial pocket 112.

In some instances, a user may desire greater support under certain portions of their body, and lesser support under other portions of their body. In such instances, two or more rigid plates 104 can be inserted into one or more of the interstitial pockets 112 with a gap 130 defined therebetween. In some instances, the two-or more rigid plates 104 can be inserted into the same interstitial pocket 112. In other embodiments, particularly where differing levels of support are desired, the two or more rigid plates 104 can be inserted into different interstitial pockets 112.

In some instances, a user may desire differing layers of support across the mattress 102, with the greatest support desired across a midsection of the mattress 102. In such instances, two or more rigid plates 104 can be inserted into the one or more interstitial pockets 112, wherein the two or more rigid plates 104 have a first overlapping portion 132.

Referring to FIG. 6, a mattress system 100 including three rigid plates 104 is depicted in accordance with an embodiment of the disclosure. In some instances, a user may desire differing layers of support across the mattress 102 with several areas of greater support across a midsection of the mattress 102. In such instances three or more rigid plates 104 can be inserted into the one or more interstitial pockets, wherein the three or more rigid plates have a first overlapping portion 132 and a second overlapping portion 134.

In operation, a user can selectively customize their mattress system 100 to provide the desired structural support and firmness for their body type and weight by positioning one or more rigid plates 104 within the interstitial pockets 112 defined in mattress 102. For example, in one embodiment, a user may desire greater support uniformly across the entire mattress 102. In such an instance, the user can insert one or more rigid plates 104 in a single interstitial pocket. Placement of the rigid plate 104 in the interstitial pocket 112 closest to the top/sleeping surface of the mattress 102 will provide maximum support, while placement of the rigid plate 104 in the interstitial pocket 112 farthest from the top/sleeping surface of the mattress 102 will provide minimal support.

In instances where differing levels of support are desired across the mattress 102, two or more rigid plates 104 can be positioned in different interstitial pockets 112. For example, a first rigid plate 104A can be placed in a first interstitial pocket 112, and a second rigid plate 104B can be placed in a second interstitial pocket 112. Where no support is desired in a midsection of the mattress 102, a gap 130 can be left between the first rigid plate 104 and the second rigid plate 104. Where greater support is desired in a midsection of the mattress 102, the first rigid plate 104A and the second rigid plate 104B can be positioned such that they establish an overlapping portion 132.

Where a more complex level of support is desired, a third rigid plate 104C can be inserted into an interstitial pocket 112. In some instances, a gap 130 can be left between the third rigid plate 104C and the first and/or second rigid plates 104A/B. In other instances, a second overlapping portion 134 can be established by overlapping the third rigid plate 104C with either or both of the first and second rigid plates 104A/B.
