Definitions
- the present disclosure relates to the field of bedding, and particularly to contour sheets or fitted sheets that may be used to cover a mattress.
- Bedding sets typically include bed skirts, contour sheets or fitted sheets that cover the mattress, top sheets or flat sheets, blankets or duvets and pillow shams among other items.
- Contour sheets which are also known as fitted sheets in some countries, not only provide comfort, but also provide the advantage of the contour sheets being washed regularly instead of frequently washing mattresses, thereby providing equivalent effect of cleanliness and hygiene, which in turn increases user convenience and reduces associated costs and resources on a recurring basis, Additionally, these items also provide an appealing bed presentation especially with apt color combinations and designs.
- an important aspect from the point of view of aesthetic appeal, comfort and safety is how well the bedding items are laid and avert accidents due to overhanging portions that may cause tripping, loose contour sheets that come off from frequent use and fail to serve the intended purpose.
- Mattresses are generally available in standard sizes such as King, Queen, Twin, Full and the like. A lot of research has been put into modifying mattress quality to meet consumer demand for improved sleep experiences. Accordingly, the market has been flooded with different types of mattresses that have different types of fillers and thicknesses and aim to provide individualized comfort to consumers. It is noteworthy that the size of the mattress continues to be standard but these innovations have resulted in mattresses with varying depths. Likewise, sofas, couches, love seats and tuffets can have standard sized cushions but with varying depth depending on consumer preferences directed at firmness, softness, bounce, and the like. A contour sheet or fitted sheet is a critical and basic item in bedding sets that is laid over the mattress and is intended to snugly fit the mattress.
- Contour sheets can also find application in seat cushions and tuffets. With varying depths of mattresses and seat cushions available in the market today, there is a need to ensure that contour sheets are standardized for a particular size and are yet able to cater to the varying depths of mattresses or cushions available for each size.
- Contour sheets are required to be durable enough to support weight of the person(s) sleeping on the mattress or sitting on the cushion. Sleeping or sitting entails a lot of movement, tossing or turning that tend to ruffle the intended fitted look and feel of contour sheets. Loosening can result in contour sheets coming off the mattress and entangle with the top sheet causing discomfort and hazard. Elasticity provided to secure contour sheets around mattresses and cushions also become un-effective over repeated wash and use.
- the present invention in its various embodiments addresses the above and other possible needs relating to the field of contour sheets or fitted sheets.
- contour sheets which are also known as fitted sheets in some countries, and methods of making thereof.
- a contour sheet having a top surface and a plurality of side surfaces can be characterized by at least one of the side surfaces being configured to be resilient and extendible in a vertical direction, along the depth of a mattress on which the contour sheet may be spread. Having at least a portion of the side surfaces resilient ensures that the contour sheet is releasably secured in position on the mattress.
- At least a portion of the side surfaces can be provided with at least one resilient member that can be configured to be extendible along the depth of the mattress.
- the at least one resilient member can be sandwiched between one or more layers of fabric to evade exposure of the resilient members to external factors such as high temperature during laundry cycles and increase durability and effectiveness of the same.
- each of the sets can include a plurality of resilient members configured to be extendible in a vertical direction, along the depth of a mattress on which the contour sheet may be spread.
- each of the plurality of resilient members constituting the sets of resilient members can be further sandwiched between one or more layers of fabric for minimizing exposure to external factors such as high temperature that can be detrimental to the durability and effectiveness of the resilient members.
- a method of making a contour sheet having a top surface and a plurality of side surfaces can include the step of coupling at least a portion of the side surfaces with at least one resilient member that can be configured to be extendible in a vertical direction, along the depth of a mattress on which the contour sheet may be spread.
- the step of coupling can include the step of sewing the at least one resilient member sandwiched between one or more layers of fabric.
- the method of making a contour sheet can further comprise cutting a generally polygonal shaped cutout at the corners of the fabric to form an opening with at least two edges, coupling at least one resilient member along at least one edge of the opening and sewing adjacent edges of the opening together.
- the step of coupling can include the step of sewing a fabric attachment that generally conforms to the shape of the opening; the fabric attachment having at least one resilient member along at least one edge of the fabric attachment.
- FTG. 1 illustrates a schematic representation of an exemplary contour sheet provided with a plurality of resilient members disposed along mattress side surfaces in accordance with an embodiment of the present disclosure.
