Wood and wood-based materials are used for the supporting substructure, which ensures the long-term stability of the furniture. Elements that have to withstand more stress are made of hardwood and softwood. Wood-based materials such as chipboard are used as surfaces such as the rear wall.

2. Seat structure

NOSAG springs, also known as steel wave springs, are stretched over the seat frame as an elastic basis. When you sit down, the spring base gives way in a targeted manner. After getting up, the springs return to their original position in a stable form.

3. Basic padding

The comfort of LETTA is already recognizable in the look. This continues in the seat. Instead of the basic version with polyether foam, you can opt for a cold foam with a fixed degree of hardness or a flame-retardant basic upholstery. Cold foam surpasses polyether foam even further in its adaptability and air permeability.

4. Back padding
