These mattresses are the core items of the AiR collection, providing athletes with conditioning sleeping gear. Training, nutrition and a good night’s sleep are equally important for maintaining a high stamina. The concept is therefore focussed on well-thought-out sleep management, which specifically sets out to ease the strain on shoulders and the back. The mattresses, made of urethane foam, feature a special multilayer structure, with the different colours for each layer thus representing various functions and states of firmness. The mattresses’ many protuberances adjust to the body to ensure a natural sleeping position. At the same time, a feeling of weightlessness arises through the natural weight distribution of the body. Also included in the collection is a portable overlay so that athletes may enjoy sound sleep while competing away from home.
