The vinyasa mattress has absolutely changed my life. A friend in Florida had a mattress from this company, so I was lucky enough to test it out there, and it was BEYOND worth going through the effort to ship one to my home in Pennsylvania. The mattress is firm enough to be supportive but also yields to certain pressure points so you feel it working for you. I wake up refreshed every am and can't imagine life without it. Also - the company was an absolute pleasure to deal with and I cannot recommend them more highly as far as their costumer relations go!
