A good starting point are the seats that come stock on high-end bikes by large brands (e.g. Specialized Bridge, WTB Volt/Silverado, Selle Italia SLR). These usually are models which work well for many people. Measuring sitbones is helpful to get the correct width. Don't need a dealer for that, you can do it yourself with a piece of compressible cardboard.
Yeti & santa cruz both use WTB saddles with their brand logo
