1. Frame

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

Comfortable to lean on and elastic for the back. High-quality polyether foam is used for the backrest due to these material-typical advantages. The foam also convinces with good ventilation.

5. Fine padding

The soft padded fleece mat adapts snugly to the contours of the body when you sit down. The protective layer between the cover and the foam is the last piece of padding under the fabric or leather cover and provides additional padding for the seat and backrest with the finishing touch.

6. Cover

Bright yellow, calm beige or timeless grey? A wide range of cover materials in over 600 variants, from artificial leather to fabric in different designs are available for your individual selection. Give the sofa its own character.

7. Armrest

There are three different armrest variants to choose from. A 10 centimeter, 15 or 20 centimeter wide armrest can be added to the living area as desired.

8. Feet

The standard height of the feet is 10 centimeters. Choose from the base materials aluminium, chrome, wood or metal. Optional casters can also be attached for easy repositioning.
