  • Happy with purchase!
Size: Queen Style: 14 Inch
The mattress is extremely comfortable! I was really weary of buying a mattress in a box ut this bed has not disappointed me or my husband. The edge support could be better but the firmness is perfectly between being firm and soft. It does t smell like chemicals and the overall quality was great for the price! Above and beyond my expectations! ... show more

  • Best night’s sleep in memory
Size: Queen Style: 14 Inch
Had it two weeks now and I wonder what took me so long. I have never had a better mattress. It’s like sleeping on a cloud. I have to admit I was a bit scared when I first sat on it because I sank down so far but once I lay on it… pure heaven.
