In modern, industrial upholstered furniture manufacture, we differentiate between the following types of upholstery:

Loose or very loose upholstery

Soft upholstery structure with no tensioning where crease formation in the covers is desirable and characteristic of the product. “Very loose upholstery” has a very soft, squashy surface. Even when new, crease formation in the covers is pronounced, which is intentional, due to construction and design. Undulation, hollow or crease formation as a result of use and depending on intensity of use cannot be avoided. In order to keep an even appearance, Stiftung Warentest also recommends regularly using all elements of the upholstered furniture as evenly as possible instead of having just one “favourite seat”. Loose and fitted seat or back cushions and upholstery must be regularly shaken out, plumped up and smoothed out depending on intensity of use but every day if necessary to achieve the pillow or feather bed effect.

Taut upholstery

In this type of upholstery, the cover is stretched taut over the piece of furniture and attached to avoid excessive crease formation during use. In most cases, creases formed while sitting smooth out again. However, it is not possible to rule out crease formation as the furniture is used for longer, which is down to the natural elasticity of the cover fabric. This type of upholstery can typically be recognised by its linear appearance. The sitting experience is different from other types of upholstery in that you do not sink very deeply into the upholstery, but sit firmly on top of it. ATTENTION: depending on duration of use and body weight, it is not possible to prevent seats from becoming less firm.

Upholstery covering with mats/chamber cushion

Mats and chamber cushions are a high-quality type of upholstery covering that adapts specifically to the body. This is achieved by using a mix of loose foam rods and fibres that can move and adapt individually. To prevent the filling from shifting, the mats/cushions are quilted into chambers. Depending on the type of cover, the chambers may stand out clearly on the surface. Formation of sight hollows as a result of use is proof of how the upholstery adapts individually to the body and is typical of the product. The original form can be regained by plumping up and smoothing out the cushions (pillow effect).

Formation of undulations and hollows (crease formation)

Seat hardness and appearance usually change after just a short time when the furniture is “bedding in”. Seats soften depending on type and duration of use and weight of user. This is a normal process that every piece of upholstered furniture goes through. To keep seat hardness even for as long as possible, it is important to keep changing your favourite spot on the upholstered furniture, otherwise one-sided undulations or hollows may occur. This development is supported by the fact that the cover materials stretch to a lesser or greater extent under the influence of body weight and heat, forming “undulations”. The visual change has virtually no influence on function or durability and is not a material defect. Smoothing out or plumping up covers and cushions is part of routine care. It may need to be done daily, depending on intensity of use (feather pillow effect).
