Throughout the history of interior design and decorative arts, few materials have managed to maintain such an intimate dialogue between functionality, durability, and sobriety as vegetable-tanned cowhide leather. Far from being conceived as a superficial covering element, true cowhide leather has been, since the early avant-garde movements of the 20th century, an architectural material in its own right.
At JoverValls, the uncompromising selection of the finest raw materials is not merely an ephemeral aesthetic statement; it defines the identity and soul of each of our pieces. Understanding cowhide leather means delving into its history, the nobility of its origin, and the artisanal discipline that transforms it: the centuries-old tradition of saddlery.
From the French Avant-Garde to Designer Furniture
The use of leather for structural and decorative purposes in high-end furniture reached its turning point in the 1930s and 1950s, thanks to great masters of French modern design. Visionary creators like Jean-Michel Frank and Jacques Adnet understood that leather brought a patina of dignity and a warmth that the cold metal of the industrial era urgently needed.
Adnet, renowned for his collaboration with legendary saddlery and leather goods firms such as Hermès, pioneered the association of leather with brass and tubular steel to create iconic pieces that are now true treasures in international auction houses like Sotheby's or Wright (as highlighted by Architectural Digest in its monograph on Jacques Adnet).

That aesthetic revolution demonstrated that leather should not be hidden behind complex upholstery over wood, but proudly displayed: firm, taut, visible, and in direct dialogue with metal. This premise necessarily demands an exceptional type of leather and a very specific way of working with it. |
The Nobility of Cowhide Leather and its Structural Behavior
For leather to play a structural role—supporting body weight in suspension and maintaining its geometry without deforming—not just any leather is suitable. At JoverValls, we exclusively select European cowhdie leather, obtained from animals raised in controlled conditions that guarantee a uniform and resistant fibrous density.
We work with the most noble part of the hide: the full grain, which retains its intact top layer without corrective sanding or plastic coatings. With a minimum thickness of 3.5 mm, this leather is among the thickest and most robust in the contemporary design landscape.
| This density gives it a powerful presence and a very particular mechanical behavior: it does not fold easily or behave like a soft fabric, but rather possesses an almost sculptural firmness. And it is precisely this robust nature that determines the hands that must shape it. |  |
The Choice of Saddlery: When Craft Defines Durability
Traditional leather crafting encompasses very distinct technical universes. While leather goods have historically specialized in manipulating thin, flexible, and folded leathers for creating bags and small garments, saddlery is rooted in a field where technical demands were absolute: equestrian harnesses, traces, and saddles.
In the saddler's workshop, the strength of a seam and the solidity of thick leather were not decorative matters; security and durability against extreme mechanical stress depended on them.
For this reason, at JoverValls, we entrust the crafting of our seats to master saddlers. Saddle leather over 3.5 mm thick demands specific treatment that only this trade masters: manual beveling and edge dyeing, hand-polishing of each edge, and the execution of seams with high-density waxed threads that pierce the leather without weakening its internal structure.

In the hands of the saddler, the leather is not conceived as a mere cover; it is mounted under direct tension on steel or brass structures, transforming the leather itself into the supporting element of the seat. |
"Worth Inherit": The Value of Noble Aging
By foregoing synthetic finishes that mask the material, vegetable-tanned cowhide leather retains its living character. The small variations in tone, slight marks, or subtle textures inherent to the animal are not flaws: they constitute the biological certification of a One of a Kind piece.
Over the years, with exposure to light and daily use, the leather absorbs the history of the space it inhabits. Far from deteriorating, it develops a lustrous and deep patina that enriches its visual and tactile presence.
This is the vision that guides every project at JoverValls: to merge the heritage of the great masters of the 20th century with the technical mastery of traditional saddlery to conceive pieces that transcend fashion trends. Designer objects created with such rigor and material honesty that they are destined to become tangible assets: pieces conceived, from their origin, to be "Worth Inherit" — worthy of being inherited and valued from generation to generation.
