Pillowtop/panel attachment gusset with ruffled corners

A mattress having a panel on one side of a mattress innerspring, a gusset attached generally about a perimeter of the panel, the gusset made of a piece of material folded about a length dimension, wherein the gusset is attached to the panel proximate to a fold in the gusset material, a first edge of the gusset opposite the fold attached to a perimeter of the panel, a second edge of the gusset adapted for attachment to another panel, and corners of the gusset having one or more pleats forming a ruffled gusset corner.

A pillowtop mattress having a mattress innerspring defining two parallel and spaced-apart support surfaces and an orthogonal sides between the support surfaces, the innerspring being covered by a panel over each support surface and a border over the orthogonal sides, perimeter edges of the panels being joined to edges of the border to encapsulate the innerspring in upholstery material,

• a gusset sewn about a perimeter of at least one panel, the gusset being in the form of a continuous strip of material which is folded along a length dimension and sewn proximate to the fold to the panel so that first and second edges of the gusset opposite the fold are generally aligned with a perimeter of the panel,
• the gusset having one or more pleats at corners of the panel, the pleats forming a ruffled gusset corner whereby the first edge of the gusset opposite the fold is configured for attachment to the perimeter of the panel, and the second edge of the gusset configured for attachment to an overlying pillowtop panel, whereby the gusset attaches a pillowtop encapsulated by the pillowtop panel to the panel covering the mattress innerspring to form a pillowtop mattress.
