Finally persuaded my other half a while ago to get rid of her sofa saddle after it ripped and all the gel leaked out! She wanted another but I managed to get her to come to the bike shop with me. After much umming and aaahing, using the arse-o-meter etc she bought one of the womens specific Spesh BG saddles…
She loves it now, and even agrees that it’s more comfortable than her old sofa one even though she swore blind at the time that she’d never be able to fit on one of those narrow(?), thin(?) saddles!!!
Well worth getting them down a proper bike shop to have a go on an arse-o-meter… they will find the saddles different for the first few rides, but then get used to them…
Oh, and it’s worth trying to make sure they are sitting properly on the saddle… ie. get them to roll their hips back and take the weight on their sit-bones, rather than their girly-bits… it’s something most blokes don’t need to worry about as things get in the way, but have noticed a few girlies, who are new to cycling, have made this mistake.
