Comes in 2 sizes, 20x50 in and full length 20x60 in. We recommend you choose body pillow based on your height so to get the right length for you. If you are over 165 cm, choose the full length 20x60 in. Body pillows give your arms and legs a rest. Weight of your arms and legs adds more work to the muscles while sleeping. Hugging a pillow will reduce workload on your muscles and maintain proper spine alignment.
