1127 Use of an Adjustable Bed Base Is Associated with Improvements in Objective and Perceived Sleep

Introduction Previous research has shown that comfort of the sleep surface is essential to sleep quality. Additionally, positional adjustment of a sleep surface can help improve sleep and alleviate discomfort. This study compared sleep in an inclined position on an adjustable bed base to participants’ prior sleep when sleeping flat in their usual bed environment. Methods Healthy adults (71% male; ages 27-75, mean age=44) reporting difficulties with frequent awakenings or time spent awake at night participated in an 8-week field study, using a pre-post intervention design. During the 4-week baseline period, participants slept flat on their regular bed. During the 4-week intervention period, they slept in an inclined position of their choosing using Sleepy’s Adjustable Bed Base. Sleep was measured objectively using a PSG-validated, non-contact biomotion device, SleepScore Max, every night and by daily and pre-post self-report. Multilevel regression and paired t-tests were used to test for statistical significance. Results There were 951 nights of tracked sleep across 27 participants. Objective sleep measurements showed increased total sleep time (+6 minutes, p=.038) and an increase in light sleep duration (+5 minutes, p=.045) compared to baseline. Also, improvement was observed in BodyScore, an objective measure of deep sleep quality (+2%, p=.030). Self-report measures revealed that using the bed base felt more comfortable compared to sleeping flat using the original bed base (p=.011). Improvements also were found for a variety of perceived sleep outcomes, including the perception of falling asleep more easily, less tossing and turning, better sleep quality, and feeling more well-rested in the morning (all ps<.001). Conclusion Several important aspects of objectively measured sleep and self-reported sleep improved when using the adjustable bed base compared to sleeping flat on the original bed base. Additionally, qualitative and quantitative self-report results indicated that the intervention was perceived as comfortable. Support (if any) Mattress Firm INC.
