The Bonell Spring Mattresses exist on the market from a long time, however, their quality has developed a lot through the years. Currently, a protective layer of felt, coir, or polyurethane foam is applied not to let the springs outside the mattress. The springs are made of a high-quality wire and are carefully intertwined which contributes to a high level of resilience and body-fitting. Another advantage is a perfect support for your back. Each of our selection of the Bonell Spring Mattresses is made of materials that don’t let the allergens (dust, mites) through and provide a perfect ventilation at the same time, which makes them the recommended mattresses for allergy sufferers.
