By Harvey Rayner - designer of the Moonleap ergonomic crescent zafu :-)
During the last 2 decades I have probably sat on over 100 different meditation cushions. My wife kindly helped me make the first prototypes of a zafu that I’d been designing in my imagination for many years. It hadn't occurred to us at first that this design could become a product that we could sell to others. The creation was originally for my bum and my bum only, but the more I used the cushion the more I felt that this was something we could share with others.
I use my Moonleap cushion for two or three hours every day. On retreats it gets a real test when we sit all day and sometimes half the night. I’m no longer troubled by legs that fall asleep when trying to stand up to join walking meditation after periods of sitting.
Before using the Moonleap cushion on retreat it always felt like I’d been kicked in the ‘Ischial Tuberosities’ (sit bones) by someone wearing steel toe-capped boots. Now, my bum is very happy to be pain free throughout every retreat.
I’m also finding that the support the cushion provides in setting my pelvis at the right angle, means the muscles in the fronts of my thighs no longer engage to tilt my pelvis and create an upright posture. With no pain in my buttocks and no tension in the tops of my thighs, I am able to completely relax the whole of my lower body, even after many hours of sitting. Much of the pain we experience whilst sitting for long periods in Lotus postures is the result of muscular tension. Even when the source of the pain is deep stretching in tendons and pressure in the joints, this discomfort can be greatly diminished if the surrounding muscles are allowed to fully relax. The bodies conditioned tendency is to contract muscles surrounding a painful joint as a means of isolating and immobilising a perceived injury. If the surrounding muscles are also having to work in order to hold a posture, this will intensify the pain and tension in that area. Providing optimal support with an ergonomically designed cushion will minimise work done by the legs and reduce pressure points that can pinch nerves and inhibit circulation. Like this we are giving ourselves the best chance of let go of our habitual bodyMind tension that arises when discomfort comes.
