Fantastic Bed. One I highly recommend. Expensive but well worth the investment. Warranty on springs 20 years. Padding is separate and can be replaced as it will not last 20 years. Very supportive for your spine. Hand made in Sweden. Helped my husbands back problems. We both sleep wonderfully. Hate to go away unless we are sleeping in another Dux Bed. They are in the Heritage House in Mendocino if you want to try one out. Definitely buy yourself a Dux Bed.
