A side-by-side refrigerator features two vertical compartments, one for fresh food and the other for frozen items. This design allows easy access to both sections without bending down, making it convenient for users. The refrigerator typically includes adjustable shelves, door bins, and sometimes a water and ice dispenser. These appliances come in various sizes and styles, fitting different kitchen layouts. Energy efficiency ratings are important to consider, as they can impact electricity costs. Many models also offer advanced features like temperature controls and smart technology, enhancing usability and food preservation.
