The right measure

A permanent quest

The rider must

Be in the right place in the saddle (naturally and without effort) in order not to overload the horse's forehand. To make appropriate requests to his horse according to his level of education.

The horse requires

Have the saddle in the right place on his back to balance your load and free your shoulders. To give useful answers and mobilize its forces in the movement.

This harmony is necessary to obtain Relaxation, Balance and Lightness.

These results are indispensable in all Equestrian Disciplines. 

Most of the equestrian peoples have realized it instinctively.

Dr Dominique Giniaux, inventor of equine osteopathy, explained it scientifically. 

We have been building our saddles for over 40 years in this spirit.

Brand History

Inspiration Observation Respect Modern Forerunner


Inspired by the horse people, their position on the back of the horses used (for centuries) for work such as moving, raiding, war,...


Reinforced by the observations of famous "Men of Horse" (Baucher, l'Hotte, Dr Giniaux, d'Orgeix...). Gaston Mercier himself as a professional rider, rethought the saddle Tree in the early 1980s.


Respectful of the good positioning of the rider and the horse.


Resolutely modern (the market still offers wood and steel), in Hi-tech materials (carbon, epoxy, etc. ...) obtaining a precursor product that is still a school in the 21st century.

Light, resilient, thin, this saddle Tree is the soul of Gaston Mercier Saddles !

D13 Concept

Following these precepts, we build saddles that rectify the imbalance that the rider's weight can represent. (General l'Hotte)

  • Our saddles position you, without effort, about 8 to 9cm behind the market saddles. 
  • They place you on the 13° dorsal, the keystone of the spine, the most supportive point. (Dr Giniaux) 
  • They free up your horse's shoulders and facilitate thoracolumbar mobility (lowering of the hips) 


Increased motor skills and muscular relaxation of the horse. The recovered balance facilitates the exercises of the horse and thus allows the rider to better feel the sensations.
