An improved topper pad for a mattress unit wherein the topper pad is positioned on an inner spring unit and has extending outwardly from its peripherial edge a preformed lip or welting encompassing the top portion of the topper pad. The inner spring unit is covered with ticking positioned on the topper pad so its edges abut the welting. A strip of trimming fabric covers the welting and overlaps the edges of the ticking panels, the trimming fabric and the ticking panels being sewn to the welting at its base, thus, constructing a mattress unit with an attractive border which looks like fabric-covered rope and which prevents shifting between the topper pad and the ticking panels. |
