Trois Couronnes Sovereign

Trois Couronnes Sovereign Mattress

The Trois Couronnes Sovereign luxurious spring mattress is based on a spring block of 12 coils of cylindrical independent springs that have been electrically hardened. This provides protection against warping and allows the manufacturer to give a lifetime guarantee on the spring units of its mattresses.

Zoning is ensured by a multi-zone spring algorithm of 7 degrees of tension with individual mattress formulation.

The dense and even surface of the mattress combined with the elasticity of the spring block provides particular stability and orthopedic support.

The mattress has been designed to preserve the dynamics of the unique spring block. This mattress does not use rigid materials which can level out the work of the professional springs; all the layers of the materials are laid in a strictly defined order.

The fillings are of only the highest quality materials: horsehair, Talalay natural latex, natural latex with shape memory, organic cotton, Mulberry silk, cashmere bamboo, hypoallergenic fiber Tencel (Lyocel).

Winter-summer function:

Side 1: Mulberry long-fiber mulberry silk and Bamboo (summer).
Mulberry silk is a silk of the highest quality, which is produced from the threads of mulberry silkworms.

Side 2: 100% cashmere (winter).
Cashmere is a valuable natural material, the healing properties of which need no introduction.

The mattress has no extraneous odors and is absolutely hypoallergenic and safe. This effect is achieved by assembling the mattress by special technology of fixing the layers without glue - vertical hand stitching.

The spring frame uses a combination of several technologies based on the Long Last Support (LLS) system - a frame made of rolled steel and a patented material with increased strength and ventilation. This kind of frame will not deform over time and increases the ventilation of the mattress, which improves the air exchange.

The height at the top of the mattress is from 30 to 33 cm. As the mattresses are handmade, the height may vary slightly
