“What if we completely rethought the sofa?”
This is what we asked the designer, Stefan Diez, before starting to develop the
Costume sofa. This modular sofa system is the expression of our continuous
research into new materials and construction technologies, and of our ongoing
commitment to the environment. It should not be considered a closed project
but in continuous evolution.
It is following this principle that we have expanded the collection creating
Costume Lounge, a new version of the sofa that offers even more comfort and
seating space to create a true oasis of relaxation and is also available for outdoor
use. Costume Lounge uses the ottoman of the previous version combined with a
new back module that can also be used as an armrest and which, completed by
large cushions, makes the sofa cosier.
At the heart of the sitting module of Costume Lounge is a thin body made
from recycled and recyclable polyethylene, produced using rotational-moulding
technology from furniture and car industry waste. An insert made of pocket
spring cores provides the cushioning for the seat. On top of this is a thin layer of
polyurethane foam. The materials are not permanently attached to each other,
the whole is held together by a cover made of fabric that can be fastened on
using tension belts and easily removed at any time. The internal structure of
the new module is the same as the other, a thin hollow recycled polyethylene
core, completed, in this case, by a polyurethane foam padding, held fixed to the
structure by the cover.
Not only does this system use much less foam in manufacturing than
conventional sofas but most of the materials used can also easily be recycled.
All its components can be easily disassembled as no glues are used. Its infinite
modularity and flexibility in changing the coverings guarantee its longevity,
offering a timeless and future-oriented product.
