How Many Springs Should Be In The Mattress

How Many Springs Should Be In The Mattress

One of the problem points when choosing a mattress is springs. The words “Bonnel,” “independent,” “zoned,” “micro package,” “TFK” is not clear… It is not clear what the difference is between the number of springs per bed and square meter. And in general, how many springs in a mattress is better – 500, 1000, 2500? Let’s tell you everything.

Dependent and independent springs

Dependent and independent springs

First, you need to understand the terminology. The main types of spring mattresses are two:

  • with a dependent block of springs – it’s called “Bonnel” or Bonnel,
  • with independent – another name TFK (from it. Taschenfederkern – spring in the pocket) or the English version of Pocket Spring.

In the Dependent, the spring variant is connected, intertwined. And if you lie on one part of the mattress, the springs compressed by the weight will pull the neighboring, and those – more distant: so they work and depend on each other. As a result, the second person on such a mattress is uncomfortable to sleep. The lighter partner will slide to the heavier side. Turning one over the entire surface of the mattress will be the effect of a wave.

In an independent spring block, each spring is located in its own cover pocket, and they are connected by ribbons, which are stitched onto these covers. If there is no direct connection, then react to the pressure only those springs on which the person is located. Moreover, the lighter the body part, the less the spring shrinks, the smoother the person lies. On the online store website “Anatomy of Sleep,” mattresses with independent springs can be seen in a separate Catalog.

Details about the difference between spring and spring mattresses we wrote In here.

 

Sleeper and square meter

In the descriptions of mattresses, on the price tags in the store, you can see the designation “250 springs per square meter, “1000 springs per sleeper.” To understand, remember the formula:

1-bed space, 2 square meters

Accordingly, “250 springs per square meter” and “500 springs per bed” sign one number of springs in a mattress.

Now you expose marketing gimmicks. For example, if you are told that a model with 2,000 springs per sleeper is better than a model with 1000 springs per square meter, you are misled because both models have the same number.

However, often no one is going to deceive anyone. Just one manufacturer points the number of springs per square meter, and the other – on the bed. In this case, to not get confused, the specified number of springs is either divided by 2 or multiply by 2, and compare this figure only in “squares” or only in sleeping places.

 

Features of spring designs

Features of spring designs

Springs are made of hardened high-carbon steel. In independent blocks, pockets for each spring are made from a solid, resistant to constant dynamic and static load of non-woven material.

Dependent springs consist of 4 or 5 turns. To reduce their “aspiration” to shrink simultaneously, the shape of springs in many mattresses is slightly modified: in the middle, they are already on the tops wider (“hourglass”). Due to the large mobility of spirals in such mattresses, they range from 200 to 350 per bed – quite enough for support and convenience.

This is an inexpensive, familiar, mass version of mattresses, suitable for people with average body weight. Also, mattresses with the system “Bonnel” Take on Cottage or to the guest room, where the mattress is used periodically. In this case, the budget and quality option becomes the best solution.

Independent blocks use springs from

  • 6 turns – TFK,
  • 10-12 revolutions – Multi-pocket,
  • up to 14 turns in Micropocket.

These are combinations of springs of different diameters, heights, numbers of turns. In mattresses can be from 250 to 2500 springs per sleeper. The more of them, the smaller they are, the more accurate they react to the sleeper’s weight, and the neighboring springs do not react at all. Thus, they create an anatomical effect – repeating the body’s contours, orthopedic – when the heavy parts of the body (hips, shoulders) do not fail, and the lungs do not “take off” above the bed. So let’s remember another formula:

The more springs per square meter, the higher the supporting and orthopedic properties of the mattress.

In mattresses for people with a large weight or a problem spine, technology is used Dual Spring – Double twisting, when the inside of a large spring is placed small. They provide mutual support, not allowing the body to fail or excessively straighten.

In mattresses for couples, different bodyweight Developed systems of Multi-one and dual-one with spirals varying degrees of rigidity. Their number is from 500 and above per square meter. Special models solve the problem when a lighter partner needs a softer mattress, and for a heavier tougher, otherwise one sleeps “like on a bench” and the second “drowns in a wata.”

 

Are springs safe?

The buyer may reasonably wonder: is there any danger that springs in large quantities will break through the mattress and injure the sleeper? Here you need to clarify that each manufacturer gives a guarantee and indicates the optimal life of each type of mattress. Do not operate them longer: the fabric wears out, fillers are dilapidated, and from a hygienic point of view, old mattresses are unsafe.

If the mattress is not overloaded (i.e., consider the recommendations on body weight), do not use it as a trampoline (and children love to jump on mattresses). The danger large number of springs of any type does not exist. And of course, you need to buy mattress in dubai stores from well-known manufacturers.

At the same time, no matter how high-quality steel, it is not necessary to test it for strength. Over time, from excessive loads, the metal wears out, from humidity on it formed pockets of corrosion.

Dry, room temperature place, without twisting (unless it is a special mattress), without constant pressure weights, on a flat surface bed boxing, Base, catwalk, or floor – these are the optimal operating conditions of the mattress.
