Spring beds are available in a wide selection of product variations from different brands of spring bed mattresses. People often feel confused when they have to choose a spring bed mattress that suits their needs, and this is because spring bed mattresses have many variations in sizes and models, the prices of various spring beds, guarantees, and different types of springs or springs used. The demands of work and the busyness of society today make many people unable to choose and see the spring bed that suits their needs in the store directly. Therefore, this system was created as a recommendation system for people to choose a spring bed mattress that suits their needs and buy mattresses online based on community preference criteria. The recommendations given by this system are obtained from calculations using the simple additive weighting method or known as the weighted addition method. This simple additive weighting method has been tested in this research and can be implemented correctly and as needed. Based on the results of the trials that have been carried out, the user satisfaction test was found to be 88.67% concerning the end-user computing satisfaction (EUCS) model, so that the recommendation system that has been successfully built can be said to be very good for users in providing recommendations for spring bed mattresses.
