The design of shape and overall style was conceptualized on the basis of human movement. Throughout the R&D phase of the Napshell the designers conducted comprehensive researches of the ergonomics and human body. Grounded on the information of these researches the designers were able to design a shaped mattress which is comfy for a wide range of persons, regardless of height and body type. The acoustic and visual effects within the capsule make it easy to reach a state of sleep. With the optimized reclining area the Napshell facilitates a revitalizing sleep position which is relaxing for spine and back.
