My Dad always told me to invest in a few good things...a good pair of shoes, good tires and a good mattress. These are all things we use everyday and effect our health in one way or another. After laying on mattresses for weeks, I finally decided on the PranaSleep Super Vinyasa. This mattress just felt right. After the first night of sleeping on it, I knew I had made the right purchase. I woke up feeling aligned and refreshed. Previously to buying this mattress, I had been waking up feeling kind of stiff which is strange for a athletic 25 year old who takes extremely good care of his health. I believe the PranaSleep Super Vinyasa has made the difference.
