Description

Technical area

The present invention relates to an improved mattress assembly whose properties can be flexibly configured by the user and which can ensure adequate sleeping comfort over an extended period of time.

State of the art

It is known to make mattresses from a foamed material, for example a foamed plastic material. For the production of mattresses, for example, a so-called cold foam is used. Furthermore, thermoelastic mattresses and mattresses are known from a so-called viscose material. Latex is also used to make mattresses.

With conventional mattresses there is the problem that they can not be changed after purchase. For the user it is very difficult to find a suitable mattress. Furthermore, the body of a user changes over the years. Another problem is that injuries can cause back problems or other discomfort. Over the years, sleeping habits and / or sleeping position may change. In other words, over the years, a user's sleep preference may change. For example, the back sleep position, the side sleep position, the belly sleep position may be more or less preferred by a user over the years.

Disclosure of the invention

The present invention has as its object to provide a mattress assembly, which the user can adapt to his preferences after the purchase and the user can adapt to changing sleeping habits.

The object of the invention is achieved by a mattress assembly according to claim 1 and a mattress set according to claim 14. The dependent claims claim preferred embodiments.

The mattress assembly according to the invention comprises a first mattress element, a replaceable insert and a second mattress element. The first mattress element has a recess in an area that is located below the user and between the shoulder and the user's hip when in use. The replaceable insert can be detachably inserted into the recess of the first mattress element and is detachably held by the first mattress element. The second mattress element is located above the first mattress element when in use. The second mattress element has a plurality of grooves in an area under the user's shoulders and / or in an area under the user's legs, which extend at least partially along the transverse direction of the second mattress element.

The mattress assembly according to the invention has the advantage that a user can adjust the stiffness of the first mattress element by selecting an insert with a suitable hardness and inserting it into the first mattress element. The insert may be selected to have the same hardness as the first mattress element, a lower hardness than the first mattress element, or a higher hardness than the first mattress element, depending on the preference of the user. This allows the user to adapt the first mattress element to the body weight, reclining position, personal relief zones and personal preferences at home. This mattress is particularly suitable for distance selling, especially for sale via the Internet.

In one embodiment, the side facing away from the user of the first mattress element may have the recess. In this embodiment, the first mattress element may be formed flat on the user-facing side.

The second mattress element in one embodiment may be configured to be rotated about its longitudinal axis so that the grooves of the second mattress element are on the user facing side of the mattress element when the weight of the user is less than or equal to a predetermined threshold in that the grooves of the second mattress element are located on the side of the second mattress element facing away from the user when the weight of the user is greater than a predetermined threshold value. Also by this measure, the elasticity of the mattress assembly can be adapted to the needs of the user. The predetermined threshold may be a weight of about 80 kg. The second mattress element is softer from the user's perception when the grooves are facing up.

The second mattress element may be rotatable relative to the first mattress element about its vertical axis such that the plurality of grooves are selectively under the user's legs or under the user's shoulders. Usually, the grooves are under the legs or lower legs of the user because the legs are a relatively light body part. If the user desires more comfort on the shoulder, especially in the side sleeping position, the second mattress element can be rotated so that the grooves are at the level of the shoulder.

In one embodiment, the second mattress element may have a lower hardness than the first mattress element. The recess in the first mattress element may be at least partially trapezoidal in longitudinal section (trapezoidal prism). The insert may be at least partially trapezoidal (trapezoidal prism) in longitudinal section. Thereby, the insert can be stably held in its position in the recess and easily replaced. In one embodiment, the insert may be trapezoidal (trapezoidal prism-shaped) in its longitudinal section at its upper portion and rectangular (cuboid) at its lower portion. In one embodiment, the recess may be trapezoidal in longitudinal section in its inner region and rectangular (cuboid) in its outer region.

The volume of the insert may be greater than the volume of the recess. The height of the insert may be greater than the depth of the recess in the first mattress element. This achieves a particularly hard application.

The mattress assembly may further include a third mattress element disposed over the second mattress element and having a lower hardness than the second mattress element. As a result, the mattress arrangement can be made more comfortable.

The mattress assembly may include a fourth mattress element disposed over the second mattress element or the third mattress element.

The material of the fourth mattress element may have a lower hardness than the material of the second mattress element. Alternatively or additionally, the material of the fourth mattress element may have a higher hardness than the material of the third mattress element. Alternatively, or in addition, the fourth mattress member may have openings extending in the vertical direction of the fourth mattress member. Thereby, the comfort of the mattress assembly for the user can be increased.

The mattress assembly may further include a fifth mattress element disposed over the second mattress element, the third mattress element or the fourth mattress element, the fifth mattress element extending over only a portion of the second mattress element. The fifth mattress element preferably extends below the legs of the user. This causes a slight elevation of the lower extremities, resulting in better venous return. The fifth mattress element can be used together with the first, second, third and / or or fourth mattress element may be arranged in a mattress cover. But it is also possible that the fifth mattress element is arranged in a so-called topper, which forms a further mattress assembly that can be placed over the mattress assembly described above.

The material of the first mattress element may have a support foam. Alternatively or additionally, the material of the second mattress element may have a comfort foam. Alternatively or additionally, the material of the third mattress element may have a comfort foam. Alternatively or additionally, the fourth mattress element may comprise latex. Alternatively or additionally, the material of the fifth mattress element may have a comfort foam.

Each of the mattress elements may be enclosed by a separate flexible biased enclosure. The mattress elements are not glued together and can therefore be arbitrarily rotated, turned, exchanged and / or combined. Furthermore, the effect of the additional elasticity due to the grooves is enhanced by the flexible biased wrapping of the second mattress element. The wrapper may enclose the respective mattress element like a tighter bag. It is understood that the envelope must be formed of an elastic material.

The invention also relates to a mattress set comprising the first mattress assembly previously described and a plurality of inserts having a different elasticity and / or a different volume and / or a different thickness. This allows the user to flexibly adjust the hardness or elasticity of the first mattress element, whereby the mattress assembly can be distributed by means of distance selling and the user can adapt the mattress to his needs over a longer period of time.

The mattress set may comprise a second mattress assembly, wherein the second mattress assembly comprises the fifth mattress element and at least one further mattress element. The further mattress element may comprise a mattress element having a viscoelasticity and / or a mattress element having a hardness which is lower than the hardness of the first, second, third, fourth and fifth mattress element. The second mattress assembly may be a so-called topper, by means of which the mattress assembly can be adapted to the individual needs of the user.

In the mattress assembly according to the invention, the inserts fulfill an important function of the mattress assembly. Conventional mattresses of the prior art have the problem that the human body, especially in the side sleep position at the height of the hip sinks the most. As a result, the user's spine is no longer in its optimal straight horizontal position but more or less curved. This results in a high pressure on the usually very pressure-sensitive hip. On the other hand, back problems can occur. If a harder insert is used in the first mattress element, the spine is again in its optimal straight horizontal position.

Foam mattresses settle in the area of the hip after a few months of use, where they can be worn over the years there. If the user uses harder inserts in the first mattress element, on the one hand, the mattress assembly can be adapted to the anatomy. On the other hand, the process of setting or passing through can be stopped or compensated. Furthermore, the hip is relieved.

The fifth mattress element relieves the legs. From an anatomical point of view, the thighs are thicker than the knees and lower legs. Consequently, the fifth mattress element, which extends only in the region of the legs, causes a more even support surface and thus more comfort for the user.

The fact that the mattress assembly can be adapted to any user and can be configured by the user, the mattress can be distributed online to the satisfaction of users. Furthermore, resources are spared because the mattress assembly can be used over a longer period of time.
