UPdecors soft pack filling material
Sponge
High-resilience sponge: Most of UPdecors' sofas are made of high-resilience sponge, which can also be said to be high-density sponge (High density foam). The higher the density, the stronger the support. The density is expressed in D, generally ranging from 30D-80D, of which 30D-50D is more common.
Sponge around 30D is relatively soft and suitable for customers who like soft sitting feeling. Sponge around 50D has stronger support and is suitable for customers who like hard sitting feeling or have higher support requirements.
High-density sponge has good elasticity, can quickly restore to its original shape, is comfortable to sit on, and is durable. It is often used in major stress-bearing parts such as sofa cushions.
Memory sponge: It can deform according to the shape and weight of the human body, can fit the curve of the human body, and disperse pressure, but the price is relatively high.
Natural Fibers
Down: Usually duck or goose down, very soft, the sofa has a strong wrapping feeling after filling, and it is comfortable to sit on, but it is easy to shift and clump, and the cost is relatively high. The price of duck down is about 550 yuan/KG, and the price of goose down is 1000-1400 yuan/KG.
Please
note
the
effect
of
filling
with
down
in
the
left
picture.
The
cushion
will
have
obvious
wrinkles
after
sitting
on
it.
This
is
the
characteristic
of
down,
and
it
is
easy
to
shift.
Although
it
is
very
comfortable
to
sit
on,
it
is
not
as
regular
as
the
picture
on
the
right.
Cotton: natural and environmentally friendly, warm and comfortable to the touch, but poor elasticity, easy to be compacted, need to be regularly arranged to restore the fluffiness.
Artificial cotton: It feels soft, is cheap, and has a certain degree of moisture absorption, but it is not as elastic as other materials such as sponge, and its durability is also not as good as other materials such as sponge.
Different
sofa
designs
use
different
sponges,
and
now
most
sofas
are
made
of
a
combination
of
sponges
of different
densities
to
achieve
a
moderate
hardness
and
softness
effect,
such
as
the
combination
of
sponge
and
down.
