Look at the outer edge, the seat opening and the points where the seat meets the bowl. A contoured seat has a distinctive outline, such as a figure eight with narrowed sides. A notched seat has a recess that can clear a raised ceramic surface or a built-in fitting. A seat can have both features.
Figure-eight outlines, violin profiles and classic curves
Dolomite Antalia
The sides narrow between two broader ends, forming a figure eight. The range also included a close-coupled bowl with a ceramic cistern.
Kerasan Retrò
The wider front and narrowed sides give the seat a violin profile that follows the bowl’s mouldings.
Vitruvit Old Time / Sovereign
The two ends have different widths. The larger lobe sits at the back, where the bowl is widest.
Flaminia Efi
A figure-eight profile stretches along an elongated bowl, giving the seat different proportions from other classic ranges.
Hidra Ellade
The soft curves of the bowl carry through to the seat, with a less sharply defined waist.
GSI Antea Old
The top has a figure-eight outline and the bowl body has pronounced steps. The model page covers Antea Old.
Recesses around the seat opening
Vincenti Antica
Recesses along the inner edge of the seat follow the ceramic. The figure eight is visible in the opening.
Simas Sinthesis
A central recess makes room for the retractable spray in the combined toilet and bidet.
Rear and front cut-outs
FACIS/GSI Cadore
The shaping at the back follows the raised ceramic and the change in the level of the seat support.
Flaminia Valentine (tipo vecchio)
A C-shaped rear cut-out clears the raised part of the bowl on the older Valentine.
Dolomite Zagara 3P
The notch is at the front. The three-piece design also includes a rear cover strip.
