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 toFIGS. 1 and 2, a mattress system100is depicted in accordance with an embodiment of the disclosure. Mattress, system100can include a mattress102and one or more rigid plates104. In one embodiment, the mattress102can be constructed of foam and can conform to standard mattress dimensions. For example, the mattress102can 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 mattress102can include a plurality of stacked layers106A-F. In one embodiment, there are six stacked layers106. In other embodiments, there may be any number of stacked layers106. Each of the plurality of stacked layers106can include atop surface108and a bottom surface110. A plurality of interstitial pockets112can be defined by the respective top surfaces108and bottom surfaces110of adjacent stacked layers106. In one embodiment, the plurality of stacked layers106are fused together at least at one of the head of the bed114, the foot of the bed116, the lateral center of the bed118, or a combination thereof. For example, in one embodiment the mattress102is constructed as a unitary foam member, and the plurality of interstitial pockets112are cut into the side of the mattress102, thereby forming the plurality of stacked layers106.

In one embodiment, the mattress102can include a covering120configured to protect the plurality of stacked foam layers106. In some embodiments, the covering120can include a seam (not depicted) along one edge configured to selectively enable access to the plurality of interstitial pockets112. 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 plate104can be configured to be inserted into one of the interstitial pockets112. The rigid plate104can be constructed of a rigid material, such as wood, plastic, hard foam rubber, or other conventional material with an element of rigidity. The rigid plate104can include one or more handles122, configured to enable a user to more easily grip and manipulate the rigid plate104.

In some embodiments, the rigid plate104is shaped and sized to fit within an interstitial pocket112. In one embodiment, the rigid plate104has 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 layers106are fused together at least at one of the head of the bed114the foot of the bed116, the center of the bed118, or a combination thereof. For example, in one embodiment, the rigid plate104has a width of between 30-39 inches and a length of between 65-75 inches.

Referring toFIG. 3, a rigid plate104having a plurality of hinge sections128is depicted in accordance with an embodiment of the disclosure. In one embodiment, the hinge sections128can be living hinges. For example, in one embodiment, rigid plate124can be constructed of a unitary sheet having a plurality of thicknesses, wherein portions of greater thickness represent the rigid members126and portions of lesser thickness represent the living hinge sections128. In another embodiment, the plurality of rigid members126are contained in a fabric housing, wherein the fabric housing between the rigid members126represents the hinge sections128.

Hinge sections128can 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 sections128can also enable a user to told portions of the rigid plate124over on itself, thereby doubling or tripling the thickness of the rigid plate124over 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 plate124over on itself in order to double its thickness prior to insertion into the interstitial pocket112. In another example, a user may prefer additional support under their lower back, and may fold a portion of the rigid plate124over on itself twice in order to triple its thickness prior to insertion into the interstitial pocket112.

Referring toFIGS. 4 and 5, a mattress system100including two rigid plates104is depicted in accordance with an embodiment of the disclosure. In some embodiments, the length of the rigid plate104can be substantially less than the length of the interstitial pocket112. for example, in some embodiments, the length of the rigid plate304can be between 6-12 inches, between 12-36 inches, or any length that fits within interstitial pocket112.

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 plates104can be inserted into one or more of the interstitial pockets112with a gap130defined therebetween. In some instances, the two-or more rigid plates104can be inserted into the same interstitial pocket112. In other embodiments, particularly where differing levels of support are desired, the two or more rigid plates104can be inserted into different interstitial pockets112.

In some instances, a user may desire differing layers of support across the mattress102, with the greatest support desired across a midsection of the mattress102. In such instances, two or more rigid plates104can be inserted into the one or more interstitial pockets112, wherein the two or more rigid plates104have a first overlapping portion132.

Referring toFIG. 6, a mattress system100including three rigid plates104is depicted in accordance with an embodiment of the disclosure. In some instances, a user may desire differing layers of support across the mattress102with several areas of greater support across a midsection of the mattress102. In such instances three or more rigid plates104can be inserted into the one or more interstitial pockets, wherein the three or more rigid plates have a first overlapping portion132and a second overlapping portion134.

In operation, a user can selectively customize their mattress system100to provide the desired structural support and firmness for their body type and weight by positioning one or more rigid plates104within the interstitial pockets112defined in mattress102. For example, in one embodiment, a user may desire greater support uniformly across the entire mattress102. In such an instance, the user can insert one or more rigid plates104in a single interstitial pocket. Placement of the rigid plate104in the interstitial pocket112closest to the top/sleeping surface of the mattress102will provide maximum support, while placement of the rigid plate104in the interstitial pocket112farthest from the top/sleeping surface of the mattress102will provide minimal support.

In instances where differing levels of support are desired across the mattress102, two or more rigid plates104can be positioned in different interstitial pockets112. For example, a first rigid plate104A can be placed in a first interstitial pocket112, and a second rigid plate104B can be placed in a second interstitial pocket112. Where no support is desired in a midsection of the mattress102, a gap130can be left between the first rigid plate104and the second rigid plate104. Where greater support is desired in a midsection of the mattress102, the first rigid plate104A and the second rigid plate104B can be positioned such that they establish an overlapping portion132.

Where a more complex level of support is desired, a third rigid plate104C can be inserted into an interstitial pocket112. In some instances, a gap130can be left between the third rigid plate104C and the first and/or second rigid plates104A/B. In other instances, a second overlapping portion134can be established by overlapping the third rigid plate104C with either or both of the first and second rigid plates104A/B.
