As the name suggests, Spine Support is an orthopedic mattress designed to support your spine alignment during your sleep. It has a multi-layer Extra Firm core made of Ortho foam, Rebonded foam, and Rubberised Coir. The mattress core comes wrapped in an organic cotton fabric with a plush 3-layer antimicrobial foam quilt, and a breathable air mesh border; and an anti-skid bottom fabric. Looks no further for the most healthy & comfortable mattress.
