Original Liforme Yoga Mat: Our unique, and revolutionary, AlignForMe system is a combination of intelligent markers to give you as much, or as little, guidance as you need. Slipping around can make your practice ineffective, or even dangerous. We scoured the planet for the best possible materials for our Liforme Yoga Mat and we believe our revolutionary GripForMe material is the grippiest Yoga mat material currently available on earth. And it stays grippy even when \'sweaty wet\'. Throughout the design process we\'ve consulted and gathered inspiration from some of the best yogis in the Yoga cosmos. Perfectionist is a conservative term for us. We\'re exacting from start to finish and we are confident the Liforme Yoga Mat is as good as it gets. We\'ve used a strong natural rubber base and added a cushioned felt portion in between that and the top layer of the mat to provide a deep cushioned and yet very solid and stable practising surface to protect bony bits (knees and hips, for instance) from digging into the floor! The mat is 4.2mm thick. Our mat is a few inches wider and longer 185cm long x 68cm wide than regular Yoga mats making it accessible for everyone. We\'ve used naturally sourced sustainable rubber for the bulk of the mat. We\'ve also used the most \'body kind\' materials and processes to make the Liforme Yoga Mat. We\'ve etched the AlignForMe markers on the mat instead of printing with potentially harmful inks and we\'ve used a revolutionary heat-bonding process to eliminate the need for toxic glues. Our mat is also PVC-free so it doesn\'t contain any nasty \'heavy metals\' such as lead and cadmium.
