Description

The present invention relates to sofa beds, nursing room units and servers.

When a mother with an infant needs to breastfeed or change diapers while she is out, she uses a bed arranged in a dedicated space (eg, nursing room) outside (eg, shopping mall). Some of such beds have a function of measuring body weight.

For example, Patent Literature 1 discloses a technique for detecting the load of a subject on a bed.

Japanese Patent Application Laid-Open No. 2018-061908

Sit on the sofa when the mother is breastfeeding.
On the other hand, when the mother changes diapers, she places the infant in the crib.
However, since the seat surface of the crib is higher than the seat surface of the sofa, it is difficult for the mother to sit down to breastfeed. In other words, it is difficult to use the crib for both nursing and changing diapers.
Therefore, although the technique of Patent Document 1 can measure the weight of an infant on a bed while changing diapers, the technique cannot be used for the purpose of breastfeeding.

In order to achieve both the purpose of breastfeeding and changing diapers in the nursing room, it is necessary to arrange both sofas and beds.
However, there is not enough space in the nursing room, so the placement of both the sofa and the bed significantly reduces the effective space in the nursing room. As a result, comfort in the nursing room is compromised.

SUMMARY OF THE INVENTION It is an object of the present invention to ensure sufficient available space for a dedicated space for breastfeeding and diaper changing (for example, a breastfeeding room) and to provide a comfortable environment for breastfeeding and diaper changing.

One aspect of the present invention is
A sofa bed capable of forming a sofa form and a bed form,
comprising a backrest in the sofa form,
The backrest forms a bed seat surface in the bed configuration,
comprising a weight measurement sensor for measuring the weight of the person to be measured on the seat surface of the bed;
It's a sofa bed.
