Our quick opinion
Treca is a French bedding company founded in Paris in 1935. More than 85 years later, the brand continues to handcraft its mattresses in its Parisian workshop, using natural materials and artisanal techniques passed down through generations. The Triomphe is their iconic model - the one that has stood the test of time and remains an absolute reference in the premium segment of French bedding.
After 6 weeks of rigorous testing, here is our complete verdict.

The Treca legacy: 85 years of French know-how
Before diving into the technical features, it is important to understand what makes Treca unique. In a market dominated by box mattress brands launched in the 2010s, Treca represents something radically different: over 85 years of artisanal know-how, 100% French manufacturing, and a philosophy that prioritizes durability and quality materials above all.
Treca artisans learn their craft for several years before touching a single spring. Each mattress goes through about 50 steps of manual production. This is in stark contrast to the industrial production of online brands.
Composition and materials
The Triomphe is a traditional spring mattress with natural filling:
Structure from bottom to top:
1. Mattress base - Durable cotton fabric forming the base 2. Biconical springs - 1.8 mm tempered steel springs in a coil shape (wider in the center, tapered at the ends) 3. Filling layer - Carded natural wool (500 g/m²) for thermal insulation and comfort 4. Natural latex layer (3 cm) - Natural latex for surface comfort and elasticity 5. Finishing layer - Carded cotton for the final touch 6. Cover - Jacquard woven damask cotton fabric, non-removable (professional cleaning)
Total thickness: 25 cm
The biconical springs: Treca's expertise
Biconical springs (or "biconical" in bedding jargon) are a technology very different from pocket springs used in modern mattresses. Instead of being individually encased in fabric pockets, Treca's biconical springs are:
- Hand-interlaced with spiral clips, creating a homogeneous block
- Wider in the center (diameter 7-8 cm) and tapered at the ends for a progressive effect
- Made of 1.8 mm tempered steel - significantly thicker than springs in mainstream mattresses (1.2-1.4 mm)
This construction creates homogeneous and firm support, without the transition zones that can sometimes be felt with pocket springs. The sensation is that of a "full" and uniform support surface.
Comfort and sensations
First impression
Upon opening, the Triomphe emits a slight scent of natural wool and latex - perfectly normal and characteristic of quality natural mattresses. The first sensation upon contact is that of a firm yet welcoming surface: the natural latex layer slightly softens the firmness of the springs.
The Triomphe has a well-defined character: it is a firm mattress that supports without enveloping. If you are looking for the "cocooning" feel of Tempur memory foam, look elsewhere. If you want solid, precise, and elegant support, you are in the right place.
Back position
Exceptional. The Triomphe in its firm version is among the best back mattresses we have tested. The lumbar dip is perfectly filled by the biconical springs that adapt precisely to the curvature of the spine. No morning pain after 6 weeks of testing.
Side position
Very good, with a slight nuance: the natural latex layer properly absorbs pressure from the shoulders and hips, but very light side sleepers (under 65 kg) may find the firm version slightly too rigid. The medium version is then preferable.
Stomach position
Excellent for stomach sleepers: the firmness prevents the pelvis from sinking, keeping the spine in its natural alignment.
Thermal regulation: the advantage of natural materials
The wool + cotton filling of the Triomphe offers remarkable thermoregulating properties. Natural wool is hygroscopic (it absorbs moisture) and thermoregulating: it keeps cool in summer and warm in winter, which is particularly useful for sleepers with variable temperatures.
The natural latex layer, naturally breathable, complements this regulation. The result: the Triomphe is comfortably cool in summer and warm in winter - a balance that few synthetic mattresses manage to replicate.
Durability: investing for 20 years
The durability of the Treca Triomphe is its strongest selling point. The 1.8 mm tempered steel biconical springs do not deform over time. Natural materials (wool, cotton, latex) do not degrade as quickly as synthetic foams.
Treca guarantees the Triomphe for 10 years. In practice, many customers have used their Treca for 15, 20, or even 25 years. When broken down to the cost per year of use, the Triomphe becomes one of the most economical mattresses in the premium market.
