some ways to reduce cost of a mattress. They are often applied by
some manufacturers who strive for a quick profit despite the fact
that they cause finally deterioration of mattress properties.
first way: Changing of spring block construction.
majority of spring mattresses are made on the basis of biconical
spring blocks. Only a special machine assembly can provide a good
quality of such blocks.
is much cheaper to apply a manual assembly instead of a
machine one. But manual assembly cannot provide a proper spring
fixation. The springs begin to fall out causing squeaking. It's
certainly harmful in both physical and esthetic meaning.
Unfortunately it's very difficult to detect such defects while
buying a mattress.
of four turn springs instead of five turn ones allows reducing
the block cost by 10 %. But such a mattress won't be as hard
as required to provide orthopedic effects. You may detect such a
defect paying attention at thickness of the mattress. A high quality
mattress should be from 17 to 22 cm thick in ordinary state and not
less than 15 cm in a condensed form.
of frameless spring block instead of a double frame one
allows saving 10 % more. For a check press the mattress edge. It
must be hard.
out. A high quality mattress should have a number of spring rows
equal to the width of the ready-made mattress expressed in
decimeters. So there must be 16 rows in a 16 dm mattress. There
are a lot of manufacturers who reduce significantly the number of
rows. For a check press the mattress surface. It should be hard and
elastic. Place the mattress on its edge on the floor and lean it
against the wall. It must keep its form (figure on the left). If the
mattress bends significantly it proves poor quality of the mattress
(figure on the right).
second way: Application of poor quality planking.
means the layers following the shielding material. Planking is
usually made of foam rubber, felt, sheet wadding, etc.
of low thickness foamed polyurethane (less than 25 kg / m3).
It's almost impossible to detect the defect by appearance of
the mattress at once. The defect becomes evident about two months
later when the foam rubber becomes worn out causing dents in the
mattress. For a check try to examine the mattress surface. It must
be hard and elastic. Unfortunately it's very difficult to
detect this defect, so the best advice to you is not to fall into
temptation from mattresses of too low price.
of foam rubber for sheet wadding reduces significantly the
mattress cost. The problem is that this material has no elastic
properties. Poor quality of such a mattress becomes evident right
from the first month of its usage and you may notice dents and
knolls in the mattress. So don't trust advertisements that
sheet wadding is much better in ecological meaning and try to
examine the mattress surface as carefully as possible.
manufacturers have recently begun to use
coconut fibers for planking. Natural coconut fibers are very
popular and rich for useful properties. But take into consideration
that application of natural coconut fibers is extremely expensive.
So don't trust if a cheap mattress is advertised as made of
natural coconut fibers. In reality it's made of phenolics.
These components may cause allergy and bad smell, and are very poor
in elastic properties. So don't fall for this bait, and don't
trust unreasonable advertisements.
felt can be used. It is acceptable but pay great
attention at quality of the felt.
of chintz instead of jacquard. Don't be
deceived as chintz becomes shabby and frayed in a very short period
of time. It can also fall ragged or become electric. Belgian
jacquard is mostly suitable to be used for mattresses. It consists
of natural fibers (70 %) and synthetics (30 %). For a check you may
try to strain and rub the material. The problem is that only a
specialist may determine proper quality of the material.
third way: Sale of non-quilted mattresses.
mattresses have much shorter lifetime as the covering begins to slip
even when you just touch it or loan against it. For a check you may
look carefully at the quilting quality. There should be no stitch
gaps and the pattern should be rather small (re. photo below).
way for manufacturers to get higher profits is to use brand marks
names for their production of much lower quality. So while buying a
mattress of a well-known company but at lower price we recommend you
to clear up some questions:
of the block that is used in a mattress (whether it is frame or not,
the number of springs, the number of spring turns, thickness of the
wire used for the springs);
staff used in the mattress (foam rubber, felt, coconut), the
Whether glues are applied to assembly;
of the covering fabric used in the mattress (bonded, silk, jacquard),
its structure, the manufacturer;
Whether the mattress is quilted or not;
Whether the mattress has a removable covering.
