Further, a position resulting from aborting or forgoing moving to the pivoted intermediate position from the first position or from another first custom position may be referred to as a first custom position. Further, a position resulting from aborting or forgoing moving to the first position from the pivoted intermediate position or from another first custom position may be referred to as a first custom position. The first position and/or first custom position(s) may be characterized by a pivot angle less than 30 degrees, such as less than 15 degrees, e.g. 0 degrees.

The method may comprise moving the mattress assembly to a second custom position. In other words, the controller device may be configured to move the mattress assembly to a second custom position, e.g. by allowing a user to fine tune his/her position by user input to dedicated buttons on the user interface. Further, a position resulting from aborting or forgoing moving to the pivoted intermediate position from the second position or another second custom position may be referred to as a second custom position. Further, a position resulting from aborting or forgoing moving to the second position from the pivoted intermediate position or from another second custom position may be referred to as a second custom position. The second position and/or second custom position(s) may be characterized by a pivot angle larger than 30 degrees. In one or more exemplary bed systems, the seat angle, in the pivoted intermediate position of the mattress assembly, is a pivoted intermediate seat angle less than 30 degrees.

In one or more exemplary bed systems, in the second position of the mattress assembly, a secondary part angle between the back normal of the back part and the seat normal of the seat part is a second secondary part angle in the range from 45 degrees to 110 degrees.

In one or more exemplary bed systems, the controller device is configured to move the mattress assembly to the first position, e.g. from the pivoted intermediate position and/or from a first custom position. The first position may be a lying or resting position. In the first position, the mattress assembly has not been pivoted, i.e. the pivot angle is a first pivot angle of 0 degrees. In other words, the mattress assembly, in the first position, is parallel to the longitudinal axis of the bed frame.

In one or more exemplary bed systems, the controller device is, in the pivoted intermediate position and/or a second custom position of the mattress assembly, configured to receive a first secondary user input (e.g. an exit request) via the user interface, and move the mattress assembly to the second position by tilting the back part by increasing the back angle to a second back angle and/or move, such as increase or decrease, the height of the mattress assembly to a second height in response to receiving the first secondary input or exit request. The second back angle may be larger than 80 degrees, e.g. in the range from 85 degrees to 90 degrees, such as 88 degrees or 89 degrees. The second height may be in the range from 55 cm to 85 cm. In other words, the controller device may be configured to move the mattress assembly to a second position (also denoted exit position), e.g. from a second custom position and/or from the pivoted intermediate position, e.g. in response to receiving a first secondary user input (also denoted exit request) via the user interface. Thus, a user can be assisted in getting to a standing position from the pivoted intermediate position and/or second custom position(s) (sitting positions) by providing the first secondary user input via the user interface.

In one or more exemplary bed systems and/or methods, to move the mattress assembly to the first position comprises reducing a primary part angle between the leg normal of the leg part and the seat normal of the seat part, and tilting the back part. To move the mattress assembly to the first position optionally comprises determining if a first primary criterion is satisfied; and in accordance with a determination that the first primary criterion is satisfied, tilting the back part, e.g. by reducing the back angle. In other words, tilting the back part may be conditional on the satisfaction of a first primary criterion. The first primary criterion may be based on the leg angle and/or the primary part angle. The first primary criterion may be satisfied, when the leg angle is less than a leg threshold, such as 75 degrees. Thus, back part tilt may be delayed compared to leg part tilt to create a smoother transition to the first position for the user.

In one or more exemplary bed systems and/or methods, the controller device is configured to move the mattress assembly to the first position, wherein to move the mattress assembly to the first position, e.g. from the pivoted intermediate position, comprises moving, such as pivoting the mattress assembly to a non-pivoted intermediate position (e.g. with pivot angle of 0 degrees); and moving the mattress assembly from the non-pivoted intermediate position to the first position.

In one or more exemplary bed systems, the controller device is configured to move the mattress assembly to one or more intermediate positions, such as a pivoted intermediate position and/or a non-pivoted intermediate position. In the intermediate position(s), such as the pivoted intermediate position and/or the non-pivoted intermediate position, the back angle is an intermediate back angle, e.g. in the range from 35 to 80 degrees, e.g. in accordance with or based on intermediate position settings in the memory. In the intermediate position, such as the pivoted intermediate position and/or the non-pivoted intermediate position, the seat angle is an intermediate seat angle, e.g. less than 35 degrees, e.g. in accordance with or based on intermediate position settings in the memory. The intermediate seat angle may be in the range from 3 degrees to 35 degrees. A slightly tilted seat angle ensures that the user does not slide down, when the back angle is increased. In the non-pivoted intermediate position, the leg angle is a non-pivoted intermediate leg angle, e.g. less than 35 degrees, e.g. in accordance with or based on non-pivoted intermediate position settings in the memory. The non-pivoted intermediate leg angle may be less than 20 degrees, e.g. in the range from 3 degrees to 15 degrees or 0 degrees.

In one or more exemplary bed systems and/or methods, to move the mattress assembly from the first position to the second position comprises moving the mattress assembly to a non-pivoted intermediate position; pivoting the mattress assembly to a pivoted intermediate position; and moving the mattress assembly from the pivoted intermediate position to the second position, e.g. in accordance with or based on the position settings, such as non-pivoted position settings and/or pivoted position settings, in the memory.

In one or more exemplary bed systems, the controller may be configured to move the mattress assembly from a second custom position and/or from the pivoted intermediate position to the second position, wherein to move the mattress assembly from a second custom position and/or from the pivoted intermediate position to the second position comprises pivoting the mattress assembly to the second position, e.g. in accordance with or based on the second position settings in the memory.

In one or more exemplary bed systems and/or methods, to move the mattress assembly to the second position comprises moving the mattress assembly to a second height, e.g. in accordance with a second height setting of second position settings stored in the memory.

In one or more exemplary bed systems and/or methods, to move the mattress assembly to the pivoted intermediate position comprises moving the mattress assembly to a pivoted intermediate height, e.g. in accordance with pivoted intermediate height setting of pivoted intermediate position settings stored in the memory.

In one or more exemplary bed systems, the controller is configured to receive a storing request via a user interface, and store one or more bed settings, such as position settings, in accordance with the storing request. To store one or more bed settings in accordance with the storing request may comprise obtaining a current bed setting, determining if the current bed setting satisfies a bed setting criterion, and in accordance with the current bed setting satisfying the bed setting criterion, storing the current bed setting as bed setting (position settings) in the memory. Thereby, a failsafe update of bed settings is provided. The bed setting may be or comprise a height of the mattress assembly. The bed setting may be or comprise a back angle. The bed setting may be or comprise a pivot angle.

The storing request also denoted a storing user input may comprise a first storing request indicative of a back angle setting of an intermediate position e.g. pivoted and/or non- pivoted intermediate position. To store one or more bed settings in accordance with the storing request may comprise obtaining a current back angle, determining if the current back angle satisfies a back angle criterion, and, in accordance with the current back angle satisfying the back angle criterion, storing the current back angle as a back angle setting of a position setting, e.g. as back angle setting of the intermediate position (intermediate back angle setting). In accordance with the current back angle not satisfying the back angle criterion, the first storing request may be ignored, and the current back angle is not stored in the memory. Thus, a user is allowed to adjust the back angle of the intermediate position and optionally to adjust the back angle of the intermediate position in a failsafe manner in order to avoid storing of bed settings that e.g. would be damaging to the bed system during operation.

In one or more exemplary bed systems, the back angle criterion is satisfied if the current back angle is within an angle range, e.g. between 35 degrees and 65 degrees. In one or more exemplary bed systems, the back angle criterion is satisfied if the current back angle is larger than an angle threshold, e.g. larger than 35 degrees.

The storing request may comprise a second storing request indicative of a height setting of a second position of the mattress assembly. To store one or more bed settings in accordance with the storing request may comprise obtaining a current height of the mattress assembly, determining if the current height satisfies a height criterion, and, in accordance with the current height satisfying the height criterion, storing the current height as height setting of the second position (second height setting). To store one or more bed settings in accordance with the storing request may comprise obtaining a current height of the mattress assembly, determining if the current height satisfies a height criterion, and, in accordance with the current height satisfying the height criterion, storing the current height as a pivoted intermediate height setting of the pivoted intermediate position. In accordance with the current height not satisfying the height criterion, the second storing request may be ignored, and the current height is not stored in the memory. Thus, a user may be allowed to adjust the height of the second position and optionally to adjust the height setting in a failsafe manner in order to avoid storing of bed settings that e.g. would not suit or be dangerous to the user (e.g. due to risk of a user falling out of bed). In one or more exemplary bed systems, the height criterion is satisfied if the current height is less than a height threshold, e.g. less than 52 cm. In one or more exemplary bed systems, the height criterion is satisfied if the current height is within a height range, e.g. between 32 cm and 52 cm.

The storing request may comprise a third storing request indicative of a pivot angle setting of the second position (second pivot angle setting). To store one or more bed settings in accordance with the storing request may comprise obtaining a current pivot angle of the mattress assembly, determining if the current pivot angle satisfies a pivot angle criterion, and, in accordance with the current pivot angle satisfying the pivot angle criterion, storing the current pivot angle as the second pivot angle setting of the second position. Thus, a user is allowed to adjust the pivot angle of the second position and optionally to adjust the pivot angle setting in a failsafe manner in order to avoid storing of bed settings that e.g. would be damaging to the bed system during operation. In one or more exemplary bed systems, the pivot angle criterion is satisfied if the pivot angle is within an angle range, e.g. between 45 degrees and 135 degrees.

The storing request may comprise a reset request and to store one or more bed settings in accordance with the storing request may comprise storing factory settings as bed settings in accordance with the reset request.
