This article provides information necessary to assist in creation of freestall facilities in which cows thrive through designs that optimize the resting behavior of dairy cattle and provide a safe, comfortable, clean, and dry place to lie down with easy access to feed and water. Comfortable stalls require a deep-bedded surface, affording cows the cushion they need to lie down for 12 hours per day and the traction necessary to facilitate rising and lying movements. Stalls should be sized to accommodate cows using them and prevent obstructions to lunge and bob areas and impediments to normal rising and lying movements.
