7. Best possible number of springs –
perfect contour adaptation
The mere number of springs is not the crucial quality feature; at best the effort to de-
tract from the spring’s quality. A car which has 20 wheels is likely to be manoeuvred
a lot worse than one with only 4 tyres. It is rather the quality of tyres which is deter-
mining the quality. Which advantage do 2000 springs offer if their spring tension is
identical to each other? We provide for the foundation of a perfect contour adaptation
and weight distribution of the sleeping body by our composition and the related dif-
ferentiation of spring tensions featuring up to four different spring tensions along the
longitudinal axis of the mattress. How can this goal be achieved if absolutely identical
spring tensions are used, if the pocket spring core does not differentiate between
spring tensions?
8. Double pocket spring core models
Require the springs to be fixed since two springs which are mounted on top of each
other always act contray to each other instead of reinforcing each other. We were able
to experience this effect ourselves while developing the GRAND CRU N°1 mattress:
The mattress got extremely shaky when equipped with a double pocket spring core,
thus requiring a fixation which in turn would make the mattress lose its flexibility.
SCHRAMM deliberately decided to use a 12 coil spring instead since only then the
fantastic dynamics and the unsurpassed volume of GRAND CRU N°1 can be achieved.
9. Flexibility and elasticity in specific spots
We use springs with a wider diameter, arranging them deliberately not too close to
each other and not in a honeycomb shape, thereby resulting in an unrivalled flexibility
and adaptability of the mattress which is achieved by the clearance and the bars of
just 1cm width between the longitudinal spring rows (SCHRAMM in-house develop-
ment). The springs’ arrangement provides for the maximum elasticity in specific spots.
If too many springs are arranged too close to each other this elasticity is jeopardized,
generating an undesirable effect across the entire surface which may be compared to
the one observed with cold foam or latex mattresses.
1. Thermal furnace tempering –
the memory of the springs
Heat tempering is used to make steels hard and ductile. An increased hardness im-
plies an increased resistance against plastic deformation. A high ductility increases
resistance against breaking. Heating the spring keeps it from losing its reset forces
(dislocation) caused by recurring stress and provides for continuous resilience of the
spring. To achieve this result, the springs are slowly and steadily heated up to the
required temperature before cooling down equally slowly. The furnace heat tempering
constitutes a kind of maturing process which is also required to produce for example
a good wine or a good cheese. Worldwide unique – only by SCHRAMM.
2. Demagnetization
The thermal furnace tempering of the springs at approx. 300 °C takes away the
magnetic effect of the material, whereas the steel keeps its natural properties. In
addition, our manufacturing springs are copper-plated.
3. Particular woven spring pocket fabric
A particular spring pocket fabric made of 100% cotton perfectly supports the removal
of body evaporation from the inside of the mattress and provides for the best aeration
possible.
4. „Myocardial“ pocket spring core strand
Combining exquisitely processed springs and most exclusive padding materials with di-
stinct handcrafting manufacturing methods the SCHRAMM product can be customized
individually to meet the user’s specific needs. Our handmade pocket spring core also is
called „myocardial“.
5. Different spring forces/tensions
Integrated along the longitudinal axis of a SCHRAMM mattress the different springs
provide for an ideal pressure compensation while resting on it. The combination of the
different springs is available in various tension degrees.
6. Different formulas (tension degrees)
Selecting the correct formula results in the perfect supporting force being exerted on
different body weights of the users including better pressure compensation, less stir-
ring during sleep, more convenient resting, sound sleep – pure relaxation.
