In an embodiment of the present invention, an improved pump is provided to inflate and deflate a bladder of a seat. The pump has a base, a stem, a valve, a bulb, an O-ring and a cover. The O-ring holds the bulb to the base in a recess defined by two lips. The bulb has a hole in one end that can be covered by a user's finger during inflation, wherein the user compresses the bulb while covering the hole to create pressure within the chamber. Then, when the user contacts the plunger, the pressure causes air to enter the bladder. To deflate the bladder, the user contacts the plunger without covering up the hole in the bulb. The stem has a flange. The pump can connect to a seat by connecting to a seat tab and securing the tab between the flange and the base.
