Bonnell spring units are made from cone springs mutually connected by convolution. For mattresses we are using high quality patented steel wire with diameter 2,2 and 2,4mm. Each spring is separately treated to keep its resilience and prevent break apperance.
Bonnell spring units are progressively reacting on pressure firstly soft and than with increase of burden harder and harder. Advantages of mattresses made with bonnell spring units are: good airflow, stableness, strength and durability.
SUPPORT bonnell spring unit overlayed with ecological termofixed felt is progressively reacting on pressure firstly soft and than with burden increase harder and harder.
REINFORCEMENT mattress edges are reinforced by the PU foam.
COMFORT PU foam sheets are softening mattress pressure on the body.
