Abstract: The Mattress Wrap Bedding System holds bedding in place over deep mattresses. Standard-sized mattresses are accommodated including twin, full, queen, eastern king and California king. Easy changing of the bed clothes is achieved for deep heavy mattresses. Mattresses using this system can be on box springs, other foundations, platform beds, futon beds, and other flat surfaces such as steel bed platforms in truck cabs. Mattress wrap bedding includes four major components. Bedding is designed to be connected to ribbons on the mattress sides. Adjustable ribbons connect the bedding to an anchor. Bedding anchors include under-mattress, mattress cover, mattress, bed frame, and platform bed anchors. Connectors and fasteners make up the fourth major component. A smooth outer appearance is achieved for the bedding ensemble so that bulges do not appear under blankets, coverlets, quilts and comforters. Mattress wrap bedding includes bottom sheets, mattress pads, other mattress toppers, and top sheets also.
