Designed for those who prefer a balanced, supportive feel. For general firmness recommendations based on your body type, please refer to the table.

These are cone-shaped metal springs combined with a polyurethane foam and felt base. This type of spring ensures excellent air circulation, helping to prevent moisture build-up inside the mattress. Mattresses with Bonnell springs respond quickly to changes in body position. As the springs are firmly connected to one another, they tend to move as a single unit, offering firm and uniform support.

Polyurethane foam, also known as foam rubber, is an extremely lightweight material that evenly distributes body weight and helps maintain proper spinal alignment. Its firmness and elasticity directly depend on its density. T25 polyurethane foam has a density of 25 kg/m³, which means the mattress is firmer and offers stronger support for the spine. This type of foam is also more resistant to deformation, making it a durable and supportive choice for everyday use.
