System for evaluating sleeping comfort of bedding system

An evaluation system for evaluating sleeping comfort performance of a bedding system, the evaluation system comprising:

• a portable device;
• and
• a hardware system comprising:
• a thermal and moisture comfort control system for adjusting one or more bedding temperatures of a bedding and one or more bedding relative humidity of the bedding;
• and
• a biomechanical comfort control system comprising a firmness-controllable mattress and a mattress firmness control machine, the firmness-controllable mattress comprising a plurality of firmness-controllable component mattresses, the mattress firmness control machine being used for adjusting firmness of each firmness-controllable component mattress such that pressure distribution on an interface between a sleeper and the firmness-controllable mattress and the spinal alignment of the sleeper are adjustable;
• wherein:
• a mobile application executable on the portable device is configured to collect subjective opinion of the sleeper using a plurality of questionnaires, wherein the plurality of questionnaires comprises a Pittsburgh Sleep Quality Index (PSQI) questionnaire, a microclimate psychological questionnaire, a pressure distribution and spinal support assessment questionnaire, and a fabric tactile psychological questionnaire.

An evaluation system for evaluating sleeping comfort performance of a bedding system, the evaluation system comprising:

• a computational system having a tactile database comprising data and information in relation to objective mechanical test results of bed fabrics for evaluating a touch comfort of the bed fabrics of the bedding;
• a portable device;
• a cloud system comprising a cloud processor and a Big Data database of bed fabrics;
• and
• a hardware system for collecting real-time data, the hardware system comprising:
• a thermal and moisture comfort measurement system comprising a plurality of first temperature sensors and a plurality of humidity sensors, each first temperature sensor being used for measuring a temperature of a position of a bedding, each humidity sensor being used for measuring a relative humidity of a position of the bedding;
• a biomechanical comfort measurement system comprising a pressure sensing mat and a spinal alignment measurement device, the pressure sensing mat comprising a plurality of pressure sensors, each pressure sensor being used for measuring pressure on a position of an interface such that pressure distribution on the interface is obtained based on the measured pressure, the spinal alignment measurement device being used for measuring one or more spinal alignment parameters of the sleeper,
• wherein:
• the computational system is configured to receive and process the real-time data from the hardware system, and is communicatively connected to the portable device for transmitting real-time data for evaluating the bedding system and adjusting the hardware system;
• a mobile application executable on the portable device is configured to collect subjective opinion of a sleeper using a plurality of questionnaires;
• the Big Data database stores a collection of mechanical test results of the bed fabrics and the subjective opinions of the bed fabrics;
• and
• the subjective opinions are categorized according to personal demographic information enabling an extraction of relevant information from the Big Data database.
