Foam mattress have been used in Europe and Asia for decades.Innerspring mattresses #1 break down & the springs which push up on you while you're sleeping causes one to roll over because it cuts off circulation unlike foam mattresses you could lay down in one position and you will wake up in the same position, this means you got a good night's sleep. I've been selling bedding for over 25 years from Stearns and fosters to seeley, serta, simmons, etc. And these foam mattresses finally made it to the United States of America! Sleep is the most essential thing as far as health concerns, also mental health. It takes some people up to 10 days to get used to a new mattress but do not fret or be disappointed because you will adapt and you will love the all foam mattresses and your body  & mind will thank you...
