The Caravan Sports Oversized Zero Gravity Chair offers the ultimate portable comfort. The oversized model is an additional 5.3" wider, so there is more room to stretch out and unwind. The recline position of the Zero Gravity chair is designed to simulate the gravity-free environment astronauts experience in space; the reclined position elevates the legs and reduces pressure on the spine. The locking mechanism allows for an infinite number of recline positions and a headrest is provided for additional comfort or use as a lumbar support. The Oversized Zero Gravity Chair by Caravan Sports will be sure to help you rest easy wherever you are.
