We are as pleased with this model of Tempur-pedic as our first one. Our original queen-size Tempur-pedic was 10 years old and still in excellent, like new condition. The new one with foundation support is a king-size. We needed the extra sleeping space since my husband is 6'6" and find the king size is a perfect fit for the two of us. We get a great night's sleep. I have a movement disorder and sleep is very important to my health. Our Tempur-pedic gives me the support I need to relax muscles and take away the discomfort from daytime activities. I must stress that we got excellent service chatting on line with a knowledgeable Tempur-pedic associate. I provided the information from our older Tempur-pedic and she matched me up to the newer model - even better than our older prototype mattress. We gave our queen size set to my great nephew who has a very physical job - he's sleeping better, too.
