I bought 12" queen bliss. This bed is really amazing.It was three years ago that I got to know the brand "Zinus".I think bed is really important. I sleep so much that I spend almost 12 hours a day on my bed on weekends. The beds I used before had a backache when I slept or lay down for a long time. It didn't feel like I slept refreshingly even when I woke up. My back hurt and I was just more tired. Since I first bought a Zinus bed three years ago, I have felt that the quality of my sleep has improved. I had a fascinating experience where my back didn't hurt at all even after sleeping for a long time. The experience continues to this day. I am very satisfied with the Zinus bed and using it. I was looking for a new bed when I moved out, and I saw a Zinus bliss memory foam bed on Amazon.(Actually I didn't even consider other bed brands. I recognized the Zinus bed unconditionally). I was a little worried because it was more expensive than the bed I bought before, but I still had a good memory of the bed that Zinus gave me, so I bought it right away.First of all, the bed is so fantastic. I wanted a relatively hard bed rather than a soft bed, but this bliss bed was perfect for my needs. It was divided into hard and soft parts, so I felt that it supported my body firmly. The bed I bought before was good, but the bliss bed I bought this time is really my dream bed. I'm a development engineer, but it's amazing how Zinus knew exactly what I needed and designed and developed a bed. I can feel the same sense of use when I lie in the center or edge of the bed, and it's also very resilient. Also, the cooling mat kept my body temperature low on hot summer nights, and the soft fabric covered my body comfortably throughout my sleep. Above all, I am very satisfied that my back does not hurt at all in the morning because the bed supports my back well when I wake up. Thanks to this bed, I can't wait to sleep. Thank you so much to Zinus for giving me perfect sleep. I can confidently introduce this bed as the best bed.
