The generous tray on this baby scale leaves room for a soft blanket. The tray is non-tip and the softly rounded walls are high to prevent lively babies from rolling off during measurement. The LCD and digits are large and clear and a built in spirit level ensures level positioning. The tray is detachable for easy cleaning. A measuring rod can be added so that weight and length can be measured at the same time..
