A mattress cover ( 100 ) for a mattress includes a sheet ( 102 ) configured to enclose the mattress at least partially. The sheet ( 102 ) comprises an upper portion ( 104 ) to cover a top side of the mattress. Further, the sheet ( 102 ) comprises a pair of side skirt portions ( 106 ) extending from two longitudinal sides of the sheet ( 102 ), to cover two longitudinal sides of the mattress, and a pair of end skirt portions ( 108 ) extending from two transverse sides of the sheet ( 102 ), to cover two transverse sides of the mattress. A set of corner pieces ( 110 ) are stitched between the adjacent side skirt portions ( 106 ) and the end skirt portions ( 108 - 1, 108 - 2 ). The corner pieces ( 110 ) have a concave curved hypotenuse side ( 112 ).

Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority pursuant to 35 U.S.C. 119 (a) to Indian patent application Ser. No. 202421042159, filed May 30, 2024, which application is incorporated herein by reference in its entirety. TECHNICAL FIELD The present disclosure relates to the field of mattress covers. In particular, the present disclosure pertains to a mattress cover for a mattress that fits a mattress covering the sides, ends, and top of the mattress neatly and snugly and prevents the mattress cover from being easily dislodged. BACKGROUND Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art. A mattress cover is a protective bedding item that encases or fits over a mattress, shielding the mattress from stains, spills, dust mites, and allergens. The mattress cover can be typically made of materials such as but not limited to cotton, polyester, or vinyl and can be quilted for comfort or waterproof for added protection. Using the mattress cover can prolong the life of the mattress by shielding it from damage and keeping it clean. Further, the mattress cover can also be an essential component for maintaining a hygienic sleeping environment, especially for those with allergies or asthma. Existing mattress covers can have proper fitting issues. The existing mattress cover may shift or bunch-up during use, due to poor fitting, leading to discomfort to users and can potentially compromise the protection it offers. Further, the existing mattress covers may not be versatile enough to accommodate mattresses of different sizes or configurations. Furthermore, some of the existing mattress covers may not stretch or adjust enough to accommodate larger or smaller mattresses. Efforts have been made in the past to improve features and design of the mattress cover to facilitate better comfort to the users. For instance, patent document WO2008/042082A2 describes a cover assembly for a mattress that includes a first cover and a second cover. The first cover includes a top panel a bottom panel, and a continuous side panel collectively defining a cavity for enclosing the mattress. The second cover includes a top surface and a bottom surface, and is positioned over and dimensionally-sized to cover at least the top panel of the first cover. A fastener connects the second cover to the first cover along the perimeter of the second cover. However, the mattress cover disclosed in the referred document may be inefficient, due to need of extra second cover to cover the mattress. Further the referred document describes one or more zippers that extend around the perimeter of the second cover, to close the first cover and the second cover. However, frequent use and improper handling can lead to zipper damage or breakage. Further, dirt, debris, or spills may accumulate around the zipper area, requiring extra care and attention during cleaning to ensure thorough sanitation and hygiene. Furthermore, the referred mattress cover cannot be easily fitted to different sizes, and must be tailor made and specifically designed for each mattress in accordance with their size, shape, or features. There is, therefore, a need to overcome the above-mentioned drawbacks, shortcomings, and limitations associated with the existing mattress cover, by providing a mattress cover for a mattress that can neatly and snugly cover the sides, ends, and top of the mattress and prevents the mattress cover from being dislodged from the mattress. OBJECTS OF THE INVENTION A general objective of the present disclosure is to provide a simple and cost-effective mattress cover for a mattress which can overcome above-mentioned limitations of the existing mattress cover. An objective of the present disclosure is to provide a mattress cover that can allow neatly and snugly cover the sides, ends, and top of the mattress. An objective of the present disclosure is to provide a mattress cover that can be neatly and snugly fitted to a mattress with minimal efforts. An objective of the present disclosure is to provide a mattress cover that can prevent the mattress cover from being easily dislodged, such as during normal use. Another objective of the present disclosure is to provide a mattress that can facilitate a tight and secure fit, thereby preventing the cover from shifting or bunching up during use. Yet another objective of the present disclosure is to provide a mattress cover with a neat and tidy finish that can complement a bedding ensemble, thus enhancing aesthetic appeal of a bed. Still another objective of the present disclosure is to provide a mattress cover that can fit mattresses of different thicknesses. SUMMARY Aspects of the present disclosure relate generally to the field of mattress covers. In part
