The market is full of innerspring
mattresses, so choosing the best one isn’t exactly a
straightforward process. That is why it is important to have
some basic knowledge regarding the different kinds of innerspring
mattresses because knowing this can help you find the innerspring
mattress that is right for you.
There are five types of innerspring mattresses:
• Karr
• Continuous
• Knotted Bonnell
• Knotted Offset
• Marshall
Since innerspring mattresses constitute for more than 90%
of the mattresses sold, salespeople tend to be rather knowledgeable
and can provide you with a cutaway sample that represents
the mattress and what it’s made of.
So you’re studying the cutaway sample, but what does
it mean?
• Karr coils move independently from one another and
the coils are hourglass shaped with an unknotted end.
• The Continuous system uses a single strand of wire
made out of steel. This strand is strung through the entire
mattress.
• The Knotted Bonnell system has hourglass shaped coils
like the Karr, but there are 5 turns to each coil.
• The Knotted Offset system is like the Bonnel system
in that the coils are squared off at the top and bottom
• The Marshall system uses wire that is quite light,
which is because a lot of coils are used in this system. This
is the system that is found in most mattresses because it
is inexpensive.
Knowing the coil types can help you make the decision as to
what kind of innerspring mattress is right for you.
