Abstract: At least one furniture upright vertical posts or legs inserted into at least one opening in at least one furniture horizontal span (shelf, top, frame) to retain the span horizontally. Each post diverges from its apex to its base. Each opening is bounded by interior facing walls that diverge downward to complement divergence of the post at an elevated region of the post. The retention of the span at the elevated region of the post arises because of the complementary divergence, which restricts relative movement of the span relative to the post to only allow lifting of the at least one span relative to the at least one post and prevent the span from moving sideways relative to the post at an elevation of the elevated region and prevent the span from being lowered further along the post past the elevated region.

Abstract: A method of making a pillowcase and a pillowcase having a cavity that accommodates therein a pillow and having a pocket within the cavity that accommodates therein a neck support cushion. The pocket may have an opening that is fully accessible after folding the pillowcase inside out. The opening may be closed by a releasable fastener, such as fabric strips that tie to each other into knots across the opening.

Abstract: A pillowcase having a cavity that accommodates therein a pillow and having an open pocket within the cavity that accommodates therein a neck support cushion. The open pocket has a slit that is fully accessible after folding the pillowcase inside out. The open pocket may be closed by a releasable fastener, such as fabric strips that tie to each other into knots across the slit.

Abstract: A pet brush with a cleaning element for removing hairs from the brush after use. The cleaning element of the brush includes a plate with openings through which the bristles protrude. When the plate is lowered, any hairs entwined in the bristles are pushed by the plate to the tips of the bristles where they are removed. The brush also has a post mechanism to adjust the cleaning element to various intermediary positions, effectively adjusting the length of the bristles for use of the brush.
