We used to have a king memory foam mattress. I always felt like I sunk in. I had to practically crawl out of bed. My wife never got a good nights sleep. Always ache from how the "foam" contoured her body. After our children needed new mattresses, we got the brand we have now. Pillowtop euro. I sleep all night. My wife keeps telling me how good she sleeps. I can't thank you enough for a comfortable, affordable mattress!
