Many adjustable bed brands offer zero-gravity presets that position your body so that your head and feet are elevated. According to Casper, this position alleviates stress on the body and promotes benefits like improved digestion and pain relief (for those who find the position comfortable). If you enjoy the zero-gravity position, consider Saatva Adjustable Base Plus because it offers full body massage and a wall-hugging design to keep you close to your nightstand as your base moves.
