Latex
|
Latex is a viscous fluid which is extracted from the Hevea
brasiliensis tree. This fluid which quickly solidifies but
remains elastic is mainly composed of rubber and is used as
a catalyst and as a basic component for latex foam with which
mattresses, pillows and other sanitary articles are produced.
Latex is a material with the following qualities:
- it is anti-allergenic because it neither causes nor
traps dust;
- it is hygienic because it is immune to all micro-organisms;
- it is ecological because harmful expanders are not
used;
- it is ergonomic because it moulds itself according
to the body's weight. When latex is compressed it immediately
adapts itself to the body's shape, offering a certain resistance
and good support when more compression occurs. This means
it is able to respond immediately in a proportionate way to
the various degrees of pressure that it is subjected to;
- it is anatomical, because its elasticity gives firm
and comfortable support, guaranteeing correct positioning
of the spine;
- it holds its shape and does not lose its density
in the course of time thanks to its natural elastic properties.
It can bear great pressure without breaking, it is resilient
and rapidly regains its original size;
- it is anti-static given that it does not become electrically
charged when rubbed;
- it is air-conditioned and heat-regulating because
it is formed of millions of open cells which are interconnected
by a system of micro-canals optimized by the air sacs made
in the sheet. This ensures the highest degree of air permeability,
of the elimination of humidity and heat.
Latex constitutes the most comfortable form of support when
one does not have particular orthopaedic needs. However if
firmer support is required, the harder "firm-type"
mattress is available on request.
A wooden stave bed base is the most suitable support for a
latex mattress, so that air can pass between the staves. Furthermore,
given their elastic qualities, latex mattresses are highly
suitable for manually and electrically adjustable beds.

Puralattex® |
Puralattex® is an innovative material made of a newly designed
environmentally friendly elastomere which has all the properties
necessary for orthopaedic support. It features an "open-celled"
microstructure which allows it to mould itself to the body's
physiological curves in the most natural way because the air
travels from one microcell to the next when compression occurs.
In addition this movement of air enables both the body and
the mattress to breathe, thus preventing bedsores.
There is no naturally occurring material which possesses
these qualities. Puralattex is a synthetic product with propellant
components and agents which are not harmful to health ( no
CFCs ), instead they are water-based, hence avoiding the deterioration
which natural products are subject to and also enabling healthy
sleep in a correct position.
Puralattex is a longlasting material which has all the qualities
necessary for sleeping healthily: resiliency and weight-bearing
capacity to support the body ergonomically thanks to the
product's springiness. Its shape will not become deformed
through use and more importantly, unlike spring mattresses,
it will not exert uncomfortable and harmful pressure on the
sleeper; Puralattex's air permeability together with the sanitizing
and anti-static treatments it undergoes make it HYGIENIC and
ANTI-ALLERGENIC.
RESILIENCY (or ball-rebound): this is a measure of elasticity.
If a steel ball is dropped on the material the ball will bounce
and the percentage height that it reaches is the measurement
of its resilience. When this value is high it means that the
material is able to swiftly regain its original form.
Puralattex PRIMAVERA mattresses show optimal resilience enabling
them to quickly return to their original shape once the vacuum-sealed
package is opened.
WEIGHT-BEARING CAPACITY (Indentation load deflection-
ILD): this is the measurement of sagging under a certain load.
The sample is pressed with a plate to a thickness equal to
a percentage of the original thickness. The force necessary
to make the compression, expressed in Newtons, is the measurement
of how much it resists the weight. In practice, it corresponds
to the sensation of solidity. The index normally refers to
compression percentages of 25% and 65%. One of the primary
elements when considering comfort is the so-called "sag-factor"
which in practice is equivalent to the ratio sagging factor
from 65% to that of 25%. A higher value of this ratio corresponds
to a greater degree of comfort: this obviously happens when
the denominator is small, i.e. when few Newtons are necessary
- i.e. little force- for the initial compression at 25% in
respect to the subsequent one. This positive characteristic
is possessed by those materials which, after initial softness,
display more than proportional resistance.
PRIMAVERA mattresses are endowed with this ideal characteristic
because they give the feeling of softness immediately when
one lies on top of them, without giving the feeling of sagging
but rather of firm support. Puralattex's mean values are reported
below.

Merino wool |
Merino wool is a top quality yarn used almost exclusively
for clothing. Merino sheep, which hailed originally from Spain,
are the best breed for wool production. Spain was the chief
center for the manufacture of wool. The merino fiber's very
thin structure made it highly suitable for making damask cloth
which was both hard-wearing and beautiful. This yarn was prized
so much in Spain that the exportation of merino garments abroad
was considered a criminal offence until the eighteenth century.
Merino sheep were exported to Australia from Spain and there
they found their ideal habitat.
The upholstery of the Primavera mattresses made of merino
wool acts as a luxurious mattress cover which is not
only indispensable during cold and wet periods, but also absorbs
excess humidity from the body. Indeed wool boasts therapeutical
advantages over any other fiber not only in a cold climate
but also in a humid/warm climate. Wool is the most hygroscopic,
thermoregulating and insulating fiber which exists.
While sleeping, a person can lose up to half a liter of water
in perspiration and wool is the only fiber capable of absorbing
such a quantity of water, thus keeping the skin dry and comfortable.
In fact wool remains dry when it absorbs water because the
moisture is distributed to all the fibers and is then dispersed
into the air. In this way a microclimate is created in the
bed with constant temperature and humidity levels which are
the necessary prerequisites for a good night's sleep (Graph
E). Furthermore, the fact that wool is a natural fiber means
that it is not electostatically charged and thus exerts a
relaxing effect on our nervous system (Graph G) : Sleeping
in direct contact with wool results in a lowering of the heart
rate (Graph F).
Wool is a living fiber and as such, must be treated in a particular
way. Correct washing and cleaning techniques will help you
appreciate better the excellent quality of our pure new merino
wool bedding.
SOME TIPS :
Do not wash these pure new merino wool items in water nor
should chlorine be used. Wringing is not advised.
We recommend dry-cleaning with perchloroethylene using normal
procedures (with a drastic reduction in the addition of water)
and drying temperatures of 35° maximum.

Cotton & sanitizing treatments |
Cotton is a natural fiber of many virtues: it is resistant
to high temperatures, it has a great capacity for the absorption
of humidity, reducing body heat. In winter cotton retains
body heat while in summer it keeps the body cool. Cotton is
rightly called the fabric for all seasons. It does not cause
allergies and it is not electrostatic. It is immune to moths
but it can become a receptacle for dust mites and bacteria:
For this reason it undergoes various hygienizing procedures
( e.g. sanitized or actigard). However the effectiveness of
these procedures, like the wearability of the fabrics, is
not long term.
The best solution, therefore, is to regard mattresses and
other bedding as items to be replaced more frequently than
what was traditionally thought. We advise asthma sufferers
and other people with allergy problems to use commercially
available antibacterial products on a regular basis and also
to clean their households and furnishings at more frequent
intervals.
