    • 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.
    • 描述了具有倒置的顶板/边框接缝的床垫,以及在边框上接合的可选的附加装饰绳。 倒置的接缝将顶板固定到床垫盖的边界部分,以消除在常规接缝顶部接缝中发现的凹凸和折痕。 可以通过消除对昂贵的台式带边缘封闭机和/或熟练的操作者的需要来减少制造成本,因为倒置的接缝可以用传统的缝纫机或甚至手工缝合缝合。 或者,传统的带边缘机器可以用较少技术的劳动力和/或减小的带/接缝材料使用,因为所有的缝合和缝合都被倒置的接缝隐藏在床垫内。
