Comfort Single Electric Breast Pump offers the comfort and convenience of fast, easy pumping at the touch of a button. It features 3 expression settings, all of which let you sit back and relax while the pump does the work. Unlike breast pumps that only operate properly when you lean forward, the Philips AVENT Comfort Single Electric Breast Pump allows you to sit comfortably upright as you pump, while the pump's angled neck lets milk flow naturally from breast to bottle. When you are able to relax, you can produce more milk. The breast pump has an uncomplicated design with a few, lightweight parts that are easily assembled and are dishwasher safe and can be sterilized for easy cleaning. The pump features a soft massage cushion with 5 textured petals intended to help gently stimulate milk flow by mimicking your baby's natural suckling patterns. You can also use it on the go with 4 AA batteries (not included).
