1. Frame
Stev sofa | Structure Cross-section of frame

The base consists of a mixture of different materials. The cross connections and load-bearing parts are made of hardwood and softwood. The division into hard or soft wood is based on the kiln density of the wood. This value depends on the location of the tree and the associated influences that influence the growth of the tree. Flat elements are made of chipboard made of glued wood chips. The panels are made from multi-layered, larger and fine chips that lie parallel to the panel plane. The entire frame construction is based on high-quality materials and guarantees strength and stability.

2. Seat structure

Nosag springs or steel wave springs are used for the seat suspension. The springs consist of a surface-refined, hardened spring steel wire. They ensure good cushioning of the upholstery and are stretched onto the frame of the upholstered furniture. The advantage of the wave base is its durability and dimensional stability. The springs give in slightly under pressure without sinking in too much.

3. Seat upholstery

The seat is padded with high quality polyether foam. The type of foam is characterized by a so-called honeycomb structure, which gives it above-average resilience and dimensional stability. Due to its elasticity, the PUR foam returns almost suddenly to its original shape when the load is removed. Optionally, the living area can be equipped with cold foam with a fixed degree of hardness or with flame-retardant basic upholstery. Flame-retardant foam is chemically processed during production, which is used to build a fire residence.

4. Basic upholstery

High-quality polyether foam with hard fiber strips is used for the suspension of the backrest. Polyether foam is one of the PUR foams and has good air permeability. Its dimensional stability and durability have a long-lasting effect on quality, which is why the foam is made for seating furniture. Due to its elasticity, the material almost suddenly returns to its original shape when the load is removed. The back is upholstered in real, which means that the back part of the backrest is also papered with the cover material. Optionally, the back can also be covered in lining material. There are two backrest variants to choose from: smooth or with drawer.

5. Fine upholstery

For the fine upholstery, a soft, thermally bonded upholstery fleece mat made of polyester fibers is used. The upholstery fleece is a protective layer that is attached between the cover and the foam and is the last cushion under the cover material. In this way, the seat is well padded and unevenness is evened out. In addition, the mat gives the seat a full appearance and improves seating comfort.

6. Cover

From flat woven fabrics, woven velours, flocked goods to swirl fleece - you can choose from over 600 different fabrics, colors, patterns and haptics. The ottoman can optionally be covered with synthetic leather. In order to guarantee maximum design variety, it is also possible to process your own individual customer fabrics.

Flat woven fabrics: Characteristic of flat woven fabrics is the unique look in jacquard patterns, which are created by combining different types of yarns and colors.
Woven velor: In woven velor, the loops of the fabric are cut open during the production of the material and dense pile threads are incorporated, which makes the surface of the material feel extra soft.
Flock velours: Flock velours is manufactured in a unique process, whereby the base fabric and pile are connected to one another with a special adhesive technique, making the material very resistant and durable.
Wirbelflies: Wirbelflies is manufactured in a very elaborate manner and impresses with its noble suede look, which is characterized by a soft grip and durability.

7. Armrest
