A lot of people ask about my mat, which isn't your typical thin mat from Walmart, though I did use one of those for years. When my tailbone just couldn't stand the hard surfaces that I taught on anymore, I investigated into finding a cushy mat that wouldn't grind my tailbone into the floor doing Teaser or my backbone while Rolling Like a Ball. I purchased the thickest one (3/4-inch), which only goes to 56 inches long. I'm pretty tall at over 5' 7", and it works for almost all the Pilates exercises. I usually put another thin mat under it just in case I need to have a slightly longer surface. I have also considered buying two longer, but thinner Aeromat Elite mats and just doubling up. This website, http://www.ironcompany.com/, is great, and at the time of this writing, does not charge shipping! Granted, it's not the cheapest mat around, so you may want to see it as a long-term investment and a special treat to yourself. But trust me, your bones will thank you for getting one of these!
