## Abstract

The proposed technology provides a spring compression arrangement (100) for a bed mattress (11). The spring compression arrangement (1) comprises a block (1) made of an elastic material, where the block comprises a first outer surface (12a) and an oppositely positioned, second outer surface (12b), the spring compression arrangement (1) further comprises a plurality of springs (2) provided in said block (1), said springs extending in a direction from said second outer surface (12b) to said first outer surface (12a). The proposed technology also provides a bed mattress comprising such a spring compression arrangement as well as a bed comprising bed mattress comprising such a spring compression arrangement. Also disclosed is a method for producing a spring compression arrangement according to the proposed technology.

## Claims

### Claim 1

A spring compression arrangement for a bed mattress, said spring compression arrangement comprising:
a block made of an elastic material, said block comprising a first outer surface and an oppositely positioned, second outer surface; and
a plurality of springs;
said block comprises through holes, each of said through holes extending between said first outer surface and said second outer surface; and
said plurality of springs being provided in a corresponding through hole in said block, said springs extending in a direction from said second outer surface to said first outer surface,
a first plane running essentially parallel with said second outer surface;
wires having one end attached to said first plane and an opposite end attached to an upper end, closest to said first outer surface, of a respective spring;
a second plane movably arranged between said second outer surface on block and said first plane, said second plane comprising a number of holes, through which said wires are provided.

### Claim 2 (depends on 1)

The spring compression arrangement according to claim 1, wherein said upper end of each spring is provided with a cap to which a respective one of said wires is attached.

### Claim 3 (depends on 2)

The spring compression arrangement according to claim 2, wherein said cap has a hook or a hole that enables fastening said wire to said cap.

### Claim 4 (depends on 1)

The spring compression arrangement according to any of the claim 1, further comprising:
a lifting device connected to said second plane and being configured to raise or lower the position of said second plane relative said first plane thereby altering the level of compression of said elastic material block and said springs.

### Claim 5 (depends on 4)

The spring compression arrangement according to claim 4, wherein said lifting device comprises an electrically or hydraulically driven lift able to continually raise or lower the position of said second plane relative said first plane.

### Claim 6 (depends on 1)

The spring compression arrangement, according to claim 1, wherein said upper end of at least a subset of said springs protrudes a distance D above said first outer surface of said block.

### Claim 7 (depends on 6)

The spring compression arrangement, according to claim 6, wherein said distance D is selected from the interval [H/100; H/2], where H is the height in the direction from said second outer surface to said first outer surface of said block.

### Claim 8 (depends on 1)

The spring compression arrangement, according to any of the claim 1, wherein said springs comprise coil springs or helical springs.

### Claim 9

Abed mattress comprising:
a frame; and
a spring compression arrangement according to any of the claim connected to said frame.

### Claim 10 (depends on 9)

A bed comprising a bed mattress according to claim 9.

### Claim 11

A method for manufacturing a spring compression arrangement for a bed mattress, said method comprising the steps of:
providing a block of an elastic material, said block comprising a first outer surface and a second, oppositely arranged, outer surface;
creating a number of through holes extending through said block of elastic material; and
arranging a plurality of springs in at least in some of said through holes in said block so that said springs extend in a direction from said second outer surface to said first outer surface;
attaching a wire to an upper end, closest to said first outer surface, each of said springs, said wire having a length that is longer than the distance between said first outer surface and said second, oppositely arranged, outer surface.

### Claim 12 (depends on 11)

The method according to claim 11, comprising the further step of:
providing an end of each of said springs with a cap comprising a hook or a hole, whereby said attaching of said wire to said upper end of said springs is performed to said cap by utilizing said hook or hole.

### Claim 13 (depends on 2)

The spring compression arrangement according to claim 2, further comprising:
a lifting device connected to said second plane and being configured to raise or lower the position of said second plane relative said first plane thereby altering the level of compression of said elastic material block and said springs.

### Claim 14 (depends on 3)

The spring compression arrangement according to claim 3, further comprising:
a lifting device connected to said second plane and being configured to raise or lower the position of said second plane relative said first plane thereby altering the level of compression of said elastic material block and said springs.

### Claim 15 (depends on 13)

The spring compression arrangement according to claim 13, wherein said lifting device comprises an electrically or hydraulically driven lift able to continually raise or lower the position of said second plane relative said first plane.

### Claim 16 (depends on 14)

The spring compression arrangement according to claim 14, wherein said lifting device comprises an electrically or hydraulically driven lift able to continually raise or lower the position of said second plane relative said first plane.

### Claim 17 (depends on 9)

The bed mattress according to claim 9, wherein said upper end of each spring is provided with a cap to which a respective one of said wires is attached.

### Claim 18 (depends on 17)

The bed mattress according to claim 17, wherein said cap has a hook or a hole that enables fastening said wire to said cap.

### Claim 19 (depends on 10)

The bed according to claim 10, wherein said upper end of each spring is provided with a cap to which a respective one of said wires is attached.

### Claim 20 (depends on 19)

The bed according to claim 19, wherein said cap has a hook or a hole that enables fastening said wire to said cap.
