Since the arena burnt, I had to go take a lesson at another barn from my trainer. I was assigned a lesson horse and chose among the few saddles one that fit the best. It was indeed a good fit, but OH MY... how uncomfortable it was! My back was hurting it was so hard and... non springy. When my trainer asked me to do posting trot without stirrups I thought my pelvic bone was going to break or something.
So, what are those saddle marks/models you rode in and made you think you were riding in heaven?
I have no clue what brand the saddle was, though wouldn't be surprised if it was a cheap starter saddle, but it made me awfully miss my usual lesson saddle. I don't know what mark it is either, but it's so comfortable.
