## Abstract

A mattress for livestock may include a casing at least partially filed with sand. One or more drains may be provided to allow liquid to drain through the mattress. A water permeability of the one or more drains may be larger than a water permeability of the mattress at portions surrounding the drains.

## Claims

### Claim 1

A mattress for livestock, the mattress comprising:
a casing at least partially filled with sand; and
one or more drains provided in the casing and configured to allow liquid to drain through the mattress;
wherein a water permeability of the one or more drains is larger than a water permeability of the mattress at portions surrounding the drains;
wherein the casing includes a first layer and a second layer encasing the sand;
wherein the drains are formed by respective portions of a continuous layer of material forming at least one of the first and the second layers, the portions having an increased water permeability;
wherein the first layer and/or the second layer of the casing is made of a water permeable material;
wherein the first layer and/or the second layer of the casing is made of a woven material;
wherein the one or more drains are formed by portions of the first layer and/or the second layer having less dense weaving than surrounding portions of the first layer and/or the second layer; and
wherein the one or more drains are formed by floating warp threads and/or floating weft threads in the first layer and/or the second layer.

### Claim 2 (depends on 1)

The mattress according to claim 1, wherein each of the drains is confined by a seam between the first layer and the second layer.

### Claim 3 (depends on 1)

The mattress according to claim 1, wherein the sand comprises silica and/or quartz.

### Claim 4 (depends on 1)

The mattress according to claim 1, wherein at least 90 wt % of the sand has a grain size between 0.250 mm and 1.000 mm.

### Claim 5 (depends on 1)

The mattress according to claim 1, wherein the sand has an average grain size between 0.354 mm and 0.707 mm.

### Claim 6 (depends on 1)

The mattress according to claim 1, wherein the sand has a bulk density between 0.5 and 4 g per cubic centimetre.

### Claim 7 (depends on 1)

The mattress according to claim 1, wherein the casing is made from a polymer material.

### Claim 8 (depends on 1)

The mattress according to claim 1, wherein an inside of the casing comprises a plurality of compartments, wherein each compartment is substantially filled with sand.

### Claim 9 (depends on 1)

The mattress according to claim 1, wherein the casing comprises an opening that can be repeatedly opened and closed.

### Claim 10

A method of manufacturing a mattress for livestock, the method comprising:
providing a mattress having a casing and one or more drains, the drains being configured to allow liquid to drain through the mattress, wherein a water permeability of the one or more drains is larger than a water permeability of the mattress at portions surrounding the drains;
and
filling the casing with sand;
wherein the casing includes a first layer and a second layer encasing the sand;
wherein the drains are formed by respective portions of a continuous layer of material forming at least one the first and the second layers, the portions having an increased water permeability;
wherein the first layer and/or the second layer of the casing is made of a water permeable material;
wherein the first layer and/or the second layer of the casing is made of a woven material;
wherein the one or more drains are formed by portions of the first layer and/or the second layer having less dense weaving than surrounding portions of the first layer and/or the second layer; and
wherein the one or more drains are formed by floating warp threads and/or floating weft threads in the first layer and/or the second layer.
