I recently bought a Voltaire. I was up front with the rep that I was interested in used… not new. I am a very common size, and there actually were three available. I was able to get the leather type I wanted in specific, and then the used saddle was repaneled to fit my horse as well. The fitting was honestly more about the horse than it was about me. Additionally, like another individual mentioned, the rep was kind enough to check the fit on my current Dressage saddle on my horse. That saddle is an entirely different brand, and ancient. The rep didn’t mind at all though, and advised riding with a gel half pad with a little extra cushion would be fine for my horse with that saddle given the tree and shape - it fit the horse well but the old wool flocking was compressed. They told me not to bother getting the wool reflocked - it would cost a few hundred with a different unaffiliated fitter who does wool, and honestly, a good half pad would be just fine. There was zero attempt to aggressively sell me either a new OR a used Voltaire Dressage saddle… although I admittedly plan on considering and likely pursuing that in the future. The rep also checked a much older jumping saddle of mine on my horse - also a different brand and wool flocked. It didn’t fit the horse, but the rep took time to show me where the issue was, and advise on whether or not they thought it might fit another horse of mine who is less wide through the wither and shoulders. That horse was at a different barn that day - if the horse had been present, the rep was willing to check it out. Instead, they just took the time to discuss it with me and offer advice and educate me on what to look for in particular when evaluating saddle fit on the horse.
No charge for ANY of this.
I also noticed in your initial post that you mentioned you have just begun riding again as an adult, and are casually lessoning one day per week right now with this trainer. Do you own your own horse, or are you riding one of the trainer’s lesson horses? It doesn’t sound like you own a horse yet - but correct me if I am wrong. If you don’t own your own horse… was the saddle fitting only for you? Or did it also involve fitting a saddle to the lesson horse you are riding. I find it REALLY excessive that anyone would attempt to charge $450 if they weren’t fitting BOTH a rider AND a horse.
I also find it inappropriate to pressure someone just one just getting back into riding as an adult and casually doing once a week lessons to purchase a new Voltaire. if you don’t own your own horse yet… and you buy a horse in a year or two, or start riding a different horse in lessons, and the brand new saddle you just purchased doesn’t fit your new horse or a different lesson horse, you will have to sell that saddle as used, and you will be out THOUSANDS and THOUSANDS. Not fun. Buying used is definitely the correct decision for the description you provided about yourself. It’s a red flag that your trainer and this fitter aren’t telling you that, and informing you about the depreciation hit you might take immediately if that saddle doesn’t fit the next horse you ride.
I’d be polite, courteous and professional, and definitely follow up by phone with Voltaire corporate. I’d also just go ahead and look for a new trainer and barn to ride with. This does not sound like a good situation, nor does it sound ethical. Life is short and horses are expensive, and there are good trainers out there who don’t pull this sort of nonsense with clients.
