Introduction
A healthy home is an overall home environment that meets the health and comfort requirements of the three aspects of physiology, psychology, and society, including furniture, home appliances and other household products, lighting environment, thermal environment, sound environment, odor environment and other related physical environment systems, as well as other related auxiliary support systems. A healthy home must not only meet the basic product performance quality and safety and environmental protection requirements, but also meet the ergonomic requirements of convenient operation, comfortable use and good experience. With the development of my country's economy and scientific and technological progress, in addition to the quality performance and safety and environmental protection of the product itself, people have put forward higher requirements for the humanization and user experience level of the product. Ergonomics aims to design and improve the product and environment system according to the physiological and psychological characteristics of people, achieve the best match between the human-product-environment system, and ultimately achieve the humanization of the product and environment system, creating safe, healthy, comfortable and efficient working and living conditions for people. Products that meet the requirements of ergonomics can effectively improve the comfort and use quality of the product and improve the user experience level. Therefore, in addition to meeting the basic performance quality and environmental safety standards of the product, the ergonomic requirements that reflect the humanized design of the product and the level of user experience have also become a necessary indicator for judging healthy homes. With the acceleration of the pace of social life and the increase of life pressure, the quality of sleep has become a global concern. Occasional insomnia will cause fatigue and uncoordinated movements the next day, while long-term insomnia will lead to consequences such as inability to concentrate, memory impairment, and inability to work. Studies have found that in addition to environmental factors such as temperature, humidity, ventilation, lighting, and quietness (noise), another important factor affecting sleep quality is the mattress we use. To ensure a high-quality sleep, it is difficult to guarantee it by studying the physiology and psychology of sleep alone, and good mattress conditions are also required. Mattresses, as one of the main sleeping mattresses for people, are closely related to people's sleep quality and sleep experience. With the continuous advancement of material civilization and technological processes, the types of mattresses used by modern people have gradually become diversified, and mattresses have a great impact on sleep quality. However, the domestic ergonomic design and evaluation technology for mattresses is still imperfect, and there is a lack of ergonomic technical specifications recognized by the public. Whether it is a manufacturer, research institution, consumer, or third-party supervision agency, they all need a mattress ergonomics standard with technical support as a basis for designing, evaluating, purchasing, and supervising the health and comfort of mattresses. Therefore, how to study and determine the ergonomic design requirements and evaluation methods of mattresses suitable for the sleeping habits and physiological characteristics of Chinese people based on the current status of Chinese mattress design and functional characteristics has become a problem to be solved in the field of healthy home research. The development of this standard can provide a basis and reference for the design and evaluation of the health and comfort of mattresses. 1 Scope

4 Technical requirements
4.1 Body pressure distribution
4.1.1 Peak pressure
The peak pressure of the human waist should be 3kPa~10kPa. 4.1.2 Waist-to-hip pressure ratio
The waist-to-hip pressure ratio should be within 35%~70%
Softness and support
The mattress (including the main support surface and edge parts of the mattress) should have appropriate softness and good support to meet the health and comfort requirements of users when using the mattress.
4.3 Sound
The mattress should not produce noise that offends the user during use. 4.4 Smell
There should be no peculiar smell that makes the user feel obviously uncomfortable4.5
Appearance
Appearance shape (including corners) and materials should consider safety during use, and it is advisable to consider the user's good sensory experience5 Detection method
5.1 Body pressure distribution measurement
Use a pressure distribution measurement system with a range of 100kPa and an accuracy of not less than 0.1kPa for detection. Select 2 men and 2 women with a height and body mass index (BMI) between 20 and 25 as the mattress pressure distribution test load (if conditions permit, the lying dummy of the 50th percentile adult male in GB/T10000 can be used as the mattress pressure distribution test load), and measure the body pressure distribution parameters of the mattress when the user is lying flat. The test posture of the experiencer lying flat is to lie flat in the middle of the mattress, keep a supine position, keep the legs naturally apart, put the arms on the chest, and rest the head on a comfortable pillow. The height and position of the pillow should ensure that the experiencer feels comfortable. The mattress should be placed on a level ground during the test. 2 User experience evaluation
5.2.1 Overview
The technical requirements specified in the hardness and support (see 4.2), sound (see 4.3), smell (see 4.4), and appearance (see 4.5) are evaluated by the user experience. Based on the typical use scenarios of the mattress, common human-computer interaction tasks are selected, and experiencers are selected according to the characteristics of the target user group, and actual use experience is carried out according to the standardized user experience process. 5.2.2 Selection of experiencers
Based on the characteristics of the target user group of the mattress, according to the experiencer selection principles and procedures (see Appendix A), and based on the distribution of height and weight index (BMI) in GB/T10000, 5 male and female users with BMI between 20 and 25 are selected. 5.2.3 Experience Process
The user experience of the mattress should follow the following proceduresa)
The mattress with the brand information of the sample hidden is placed flat on a stable wooden bed board or a flat hard surface; the experiencer is familiar with the purpose of the mattress user experience and the mattress user experience table (see Appendix B);b)
GB/T39223.5—2020
The tester explains to the experiencer the simulated scenario tasks that need to be completed (including supine lying flat, side lying, lying flat and sitting up, etc.);c)
The experiencer tries the mattress to be tested, and the trial posture should include at least lying flat and side lying. The trial time is at least 30 minutes,d)
Complete the simulated scenario experience task;
After the experience, complete the mattress user experience table according to the technical requirements specified in 4.2 to 4.5,e)
5.2.4 Evaluation Principles
The user experience evaluation adopts a five-point evaluation principle. According to the user's feelings and experience during actual use, a five-level scoring system of excellent, good, general, poor and bad is used to evaluate the user experience. The experience evaluation results of each ergonomic indicator in the user experience table are assigned different scores, with excellent as 100 points, good as 80 points, general as 60 points, poor as 40 points, and poor as 20 points. According to the experience results of all experiencers, the comprehensive evaluation results of the user experience are obtained by calculating the average value. 3

A.1 Overview
Appendix A
(Normative Appendix)
Principles and procedures for selecting experiencers
In addition to measuring through special test procedures, the detection and evaluation of the ergonomic performance of the product usually requires the designated target users of the product as experiencers to try out the product to be tested (user experience) and give the experience results after use. The reliability of user experience results depends greatly on the extent to which the testers can represent different target users. Testers are preferred target users who can make consistent and repeatable subjective evaluations of products in the field involved. The selection of testers should follow certain selection principles and procedures to ensure the authenticity and validity of the experience results. A.2 Principles
In addition to having experience in using the product, the testers should be able to represent the target users of the product to be tested in terms of human characteristics. In the process of selecting testers, in addition to referring to key anthropometric parameters, at least the following items should be considered: Age of the user group (all ages or a specific age group); Gender of the user group (either male or female or a certain gender); -- Occupation (if relevant).
A.3 Screening
A.3.1 Purpose
Through screening, those who are not suitable to be experiencers will be eliminated. The experiencers who pass the screening will participate in training. 2 Basic information of personnel
A.3.2
Understand the following situations of candidate experiencers and decide whether to select them as formal experiencers accordinglya) Attitude towards experience objects: whether the candidate experiencers are particularly disgusted with certain experience objects, especially their attitude towards possible experience objects;
Knowledge and experience: if the candidate experiencers are required to experience a certain type of product, those who have experience with such products should be considered first;b)
Health condition: the candidate experiencers are in good health, without disability, trauma or other motor and sensory system diseases;d) Descriptive expression ability: the candidate experiencers should have the ability to express and describe subjective feelings;Personality characteristics: the candidate experiencers should show interest and enthusiasm in the subjective feeling experience work and have a serious attitude;e)
f) Other situations.
