Background and aims: Despite that 93% of people indicate that a mattress plays a pivotal role in achieving high‐quality sleep, there is a scarcity of research investigating the influence of mattresses on sleep quality, pain, and mood in nonclinical poor sleepers. The purpose was to examine the effectiveness of a pressure‐releasing medium‐firm grid mattress on sleep and health outcomes (e.g., mood, pain, daytime fatigue) of adults with nonclinical insomnia symptoms using a quasi‐experimental design. Methods: Participants were 39 adults (mean age = 45.29) with nonclinical insomnia (i.e., occasional sleeplessness). Following 1 week of baseline assessments on their current mattress, they slept on a pressure‐relieving grid mattress for 8 weeks. Participants completed self‐report assessments of the Pittsburgh Sleep Quality Index, Berlin Questionnaire, Insomnia Severity Index, Restorative Sleep Questionnaire, Perceived Stress Scale, Profile of Mood States, Daytime Fatigue Scale, Pain and Sleep Questionnaire, and Brief Pain Inventory at Baseline and Weeks 1, 2, 3, 4, and 8. Participants continually wore an Oura Ring to objectively assess sleep and daytime activity. The data were collected from January 2022 to April 2022 and were stored electronically. Repeated‐measures analyses of variance were used to analyze mean time differences. Results: Self‐reported sleep quality, perceived pain, perceived stress, mood, and daytime fatigue improved significantly from Baseline to Week 8, p's < 0.05. Objective Oura Ring validated the self‐reported sleep and daytime activity outcomes with improvements in sleep duration, time awake during the night, light sleep, deep sleep, and total sleep time, p's < 0.05. No significant time effects were evidenced for rapid eye movement sleep. No adverse events were reported. Conclusion: The grid mattress is a simple, noninvasive, and nonpharmacological intervention that improved adults sleep quality and health. Controlled trials are encouraged to examine the effects of this mattress in a variety of populations and environments. Key points: What's Known: Although numerous studies recognize that mattresses are an important environmental factor on sleep quality, limited research exists on which mattress design is optimum for improving sleep quality and overall health, especially in the natural home environment.Medium‐firm mattresses provide the best sleep quality but their effects on nonclinical poor sleepers requires more research. What's New: A quasi‐experiment intervention involving 39 adults with poor sleep quality examined the impact of a pressure‐relieving medium‐firm grid mattress on sleep quality and health.Sleeping on the grid mattress led to significantly improved sleep quality, increased daytime activity, reduced daytime fatigue, improved mood, and lowered anxiety/stress.Clinical implications.The grid mattress may be a nonpharmacological approach for promoting sleep quality, daytime activity, and overall health in people with occasional sleeplessness.
