FloatNow, Naperville

At MassageNow, the goal is to reach a state of complete relaxation. To get there, clients can enlist the soothing hands of one of the talented massage therapists or step into the spa's unique isolation tanks; here's how they work. In about 12-inches of body-temperature water, a client lays down and allows themselves to float atop the still water. The water's extremely high salt content creates a weightless, gravity-free feeling, allowing the body to float to the top without exerting any energy. Finally, all the lights are turned off, and all outside stimulation is removed, allowing guests to unwind and meditate. Afterward, they can rinse off in the private shower area and leave feeling completely renewed.
