Sleep & Fly stores sell orthopedic mattresses from the manufacturer. Our task was to develop a modern cozy design of a retail space different from others. Our constructors and designers have developed a 3D project and visualizations. We have used a minimalistic approach and modern trends. We have chosen one primary color - orange, juicy and bright, as well as two secondary neutral colors (graphite and white). The walls are decorated with a geometric pattern so snow-white stands with products and beds with mattresses look more attractive. To create a cozy atmosphere, lamps of directed warm light were used: the light streams onto the mattresses and looks like sun rays that usually illuminate the bed in the morning. We also had to follow the principles of planning a sales area: the customers way through the sales area should be convenient and easy and the environment should also be emotionally comfortable for customers to make their shopping pleasant and effective.
