New, only the outer box has been opened for photography. I received it as a prize, but I won't be using it, so I'm selling it for less than the retail price. Retail price: 66,000 yen Active Sleep ANALYZER, a sensor that analyzes sleep. Ideal for those who want to analyze their sleep to improve sleep quality, from athletes to the elderly. It can be used with most mattresses, but it seems to work especially well with Paramount Bed. - Model name: Active Sleep ANALYZER - Series: NN-1020 - Function: Sleep measurement sensor - App compatibility: Active Sleep App #Health #SleepImprovement #SleepAnalysis #MedicalCare
