Trois Couronnes Princess Mattress
The Trois Couronnes Princess luxurious spring mattress uses a spring block of 6 coils of cylindrical independent springs, electrically hardened, as the base of the mattress. This provides protection against warping and allows the manufacturer to give a lifetime warranty on the spring units of its mattresses.
Zoning is ensured by a multi-zone algorithm of springs of 3 degrees of tension with individual mattress formulation.
The dense and even surface of the mattress combined with the elasticity of the spring block makes this mattress especially stable and provides the necessary ergonomic support.
The fillings are composed only of high quality materials: Talalay natural latex, 5th generation shape memory material, rigid latex foam, organic cotton, camel hair, cashmere, tussa silk mixed with bamboo viscose, hypoallergenic Tencel fiber (Lyocel).
Winter-summer function:
Side 1: untreated long-fibre mulberry silk tussa layer and bamboo viscose (summer).
Side 2: Camel hair and cashmere (winter).
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 21 to 23 cm. As the mattresses are handmade, the height may vary slightly
