Sleep is an indispensable human need for survival, development and healthy living. Non-communicable diseases such as hypertension and cardiovascular problems which are resultant effects of lack of good sleep are major mortality factor in Nigeria. Despite several research attempts at developing technologies and methods to help induce and aid sleep, sleep problems persist. This study aimed to develop a sleep-inducing bed to reduce sleep problems among Nigerian adults. An auto-shut-off sleep-inducing bed of “1968.6×1312.4×656.2 mm” was developed using a reciprocating motion mechanism centred on an eccentric shaft application. A self-developed questionnaire, direct observation, fuzzy logic, and SPSS were used for data analysis on a total of 234 participants who were sampled for the study. Twenty seven out of the 234 participated in the testing of the bed while 207 responded to the study questionnaire. The study described sleep quality as a “function of environmental factors (Ef) or sleep disorder (Sd)”. An average of 20.37 min was achieved as the sleep onset latency (SOL) with the bed. The study revealed critical negative and positive relationships among age, nature of work, health status, body height, marriage, the timing of sleep and hobbies to sleep quality. The developed smart bed is safe, simple to use, and a sleep companion. The bed was able to achieve a 75% SOL of less than 20 min when it was tested, and the study was also able to uphold the mathematical description of sleep quality as a function of environmental factors or sleep disorders.
