The bedsheet-tucking tool kit consists of at least one bed-mattress lifter and at least one bedsheet tucker. The lifter has a handle and an insertable portion, the distal end of which tapers in the direction away from the handle. A stopper provided between the handle and the tapered portion limits insertion of the lifter to a position in which the bedsheet can fall behind the inserted portion. At its bottom, the lifter has a flared wing-like portion that maintains stability of the lifter in the inserted position. In order to increase friction between the bottom of the lifter and the boxspring mattress, a small portion of the bottom surface of the lifter is coated with a thin rubber-like coating. This protects the lifter from popping out from the inserted position. The handle may be coated with a rubber film. The tucking tool is made in the form of a spade with a rounded knob-like handle and a flat tucker blade.
