Each color does not determine density. We have three different densities across all our products. The lightest density are the Core rollers, the standard density are our Grid rollers, and our firmest are the Grid X and Carbon rollers.
If you are unable to add a product to your cart, it is most likely because you are not located in the US. Our website is not able to process international orders. If you would like to purchase, please take a look at our International Distributor’s page.
Our videos no longer need an access code. They can all be viewed by going to the "How-To Videos" section of our main navigation. If you are having any issues with videos loading, we recommend using Google Chrome to view them. We also have a YouTube channel where they are available.
It’s important to us to provide the best shipping experience, so we are now shipping everywhere in the 48 Contiguous States only. We are unable to ship to Alaska, Hawaii, Puerto Rico and the other US territories. No international orders are accepted.
