Whether the saddle is a new saddle or a used saddle, it is a major issue for the rider because sitting on it, it plays on the quality of its position and its plate. And because the riders are all physically different, a model may be perfect for your friend but not for you (and vice versa). But we will no longer look at used saddles for sale!
The used saddle that meets your needs and that of your horse
Choosing a saddle is a difficult question. It is better not to be wrong, for the budget of course, but especially for the horse. The role of the saddle is to distribute the weight of the rider on the horse's back and to absorb shocks. A function that the saddle fills perfectly when it is well chosen in relation to the horse. The problem is that once the saddle no longer responds to one of the multiple criteria of choice, it quickly becomes an instrument of torture and the horse would be better mounted raw. So if you want to buy a used saddle then, take into account these different aspects in the purchase!
This is the second-hand market ... For everything that is expensive (or cheaper, too) it's an interesting consumption habit. In terms of riding equipment and especially the saddle, it may be worth it and the cost - but beware! There are many things to know when you start buying a used saddle without going through a professional.
So, if you buy a used saddle in a good saddlery, there is a good chance that the pros have already verified that the saddle is still in use. But if you buy it elsewhere (to an individual), it is possible that the person does not have the necessary knowledge to determine if the saddle is good for the job, especially from the point of view of safety.
