Quilted mattress cover with inverted seam
View Patent ↗A mattress having an inverted top panel/border seam, with an optional appended decorative rope welting on the border is described. An inverted seam secures the top panel to the border portion of a mattress cover to eliminate bumps and creases found in conventional welted top seam. Manufacturing costs may be reduced by eliminating the need for an expensive table-mounted tape edge closure machine and/or skilled operators, since the inverted seam may be flay sewn with a conventional sewing machine or even hand-stitched. Alternatively, a conventional tape edge machine can be used with less-skilled labor and or reduced tape/welting material, as all of the stitches and welting are hidden inside the mattress by the inverted seam.
1. A mattress covering having an inverted seam, comprising:
a top panel having a perimeter edge and a finished side; and
a border having a perimeter edge and a finished side,
wherein said border is attached to said panel, with said finished side of the panel in direct contact with said finished side of the border, along the perimeter edge of at least one of the panel and the border to form the inverted seam, and wherein said inverted seam is sewn flat.
2. The mattress covering of claim 1 , wherein said inverted seam is obscured from view from said finished sides of said panel and said border.
3. The mattress covering of claim 1 , wherein said inverted seam further includes a tape encompassing said attached border and panel on a side opposite the finished side of the border and panel.
4. The mattress covering of claim 1 , further comprising
a decorative welting attached to said finished side of said panel and said border proximate to said inverted seam.
5. The mattress covering of claim 1 , further comprising
a core around which the covering may be placed and having a plurality of springs and the mattress covering includes at least one flange having two ends, with one end attached to the inverted seam and the other end secured to a spring.
6. The mattress covering of claim 5 , wherein the mattress core includes a plurality of springs and a tray encompassing the springs.
7. The mattress covering of claim 6 , wherein the tray is made of a foam material.
8. The mattress covering of claim 1 , further including a bottom panel which is attached to a peripheral end the border.
9. A mattress covering having an inverted seam, comprising:
a top panel having a perimeter edge and a finished side;
a border having a perimeter edge and a finished side; and
a decorative welting attached to said finished side of said panel and said border proximate to said inverted seam,
wherein said border is attached to said panel, with said finished side of the panel in direct contact with facing said finished side of the border, along the perimeter edge of at least one of the panel and the border to form the inverted seam.
10. A method of forming a mattress covering having an inverted seam, comprising:
arranging a panel on a mattress, said panel having an unfinished side facing the mattress, a finished side opposite the unfinished side and forming a sleeping surface, and a perimeter;
positioning a border having a perimeter, a free perimeter and a finished side in such a way that the perimeter of the border is positioned proximate to the perimeter of the panel and the finished side of the panel faces the finished side of the border; and
securing said border to said panel along said perimeter edge of at least one of the panel and the border by at least one of sewing, flat-sewing, gluing, heat-setting and stapling to form the inverted seam,
wherein said finished side of the panel is in direct contact with said finished side of the border.
11. The method of claim 10 , and further comprising attaching a decorative welting to said finished side of at least one of the panel and the border proximate to said inverted seam.
12. The method of claim 10 , further including applying a tape so as to encompass the folded border and panel and sewing along the perimeter edges through the tape, the border and the panel.
13. The method of claim 10 , further including applying a tape so as to encompass the border and panel and sewing along the perimeter edges through the tape, the border and the panel.
14. The method of claim 10 , further including folding the border over the inverted seam and a side of the mattress, so that the finished side of the border faces outwardly away from the mattress, thereby obscuring the inverted seam from view from said finished sides of said panel and said border.
15. The method of claim 10 , further including securing a second panel to the free perimeter edge of the border so as to enclose the mattress between the panel, the second panel and the border.
