Jonker mattress features

Insert materials are described in the order they are placed in the mattress for each two sides

Pure viscose fire retardant fabric

Human skin is our natural connection to the environment. It loves to touch natural materials which have a positive effect on the body, creating the ideal conditions for climate and temperature. Inside the heart of the tree trunk, cellulose is found, a pulp of the structural polysaccharide. After special treatment, it offers us unique gloss fibers from which high quality fabric is produced.

Viscose is a very durable fabric which offers great comfort during movements. Also, it has a sensation of embracing the body harmoniously so it is highly requested in textile production. The PURE VISCOSE fabric has excellent heat-regulating properties. Indeed, its structure “traps” the air, providing a natural insulating environment, as it can absorb up to 40% of moisture while reducing static electricity.

Produced according to the specifications of the European OEKO TEX STANDARD 100 & slow flammable.

Fiber wave lana

Eco-wool layer. It contains no chemical resins and glues, it is fully recyclable and hypoallergenic. A exclusively patented product technology is its structure, as the fibers are arranged in sinusoidal order, thus forming a set of waves having a horizontal arrangement. This ensures a great flexibility, excellent restoration and durability, even under high compression conditions.

Double high-resilience foam HR

The state-of-the-art high quality foam with its open cellular structure allows breathing inside the mattress and at the same time because of its high density ensures maximum performance Its behavior provides high elasticity, excellent recovery and durability even after years of use. A double layer of material is used on each side of the mattress.
