A recent survey indicates that 30% of adults in the United States sleep separately from their partners because of co-sleep disruptions (Rogojanski et al., 2013). However, research suggests that sleeping together is good for couple relationships (Holt-Lunstad, Smith, & Layton, 2010). While there are many products on the market designed to help individuals with sleep problems, there are few that address co-sleeping problems. This thesis addresses this gap in the market for co- sleeping products by exploring how a design intervention of bedroom furniture can help couples sleep together despite the disruptions to each other. This paper records the design process and the development of a functional, full-scale prototype. The resulting design is the “ECO-sleep system.” The product is effective because it minimizes disruptions caused by sound and light. However, it does not completely eliminate them. This paper provides conclusions about design potential and limitations, and recommendations for improving the design of the ECO Sleep System.
