Zero gravity feels so good because it takes all the pressure off your spine. Your feet are above your heart, you get great circulation, it eliminates swelling in your feet and ankles, and you feel great because you're almost in a floating position here. Zero gravity is a magnificent way to rest, relax, and recover.
It's a great way to sleep, and this MacZcliner makes it so easy, so comfortable to go to that zero gravity position and let total relaxation begin.
