"I have the queen soft with the comfort plus topper to add a bit of firmness . It is PERFECT. Probably the most comfortable bed I have ever slept in . Some great features that i LOVE: The mattress cover fits perfectly. The topper zips in so there is no sliding/moving and it is all one piece. I love the feel of the mattress cover and the look of it. The soft mattress felt just a bit too soft for me so adding the topper made it just right. I wanted comparable to the Temperpedic cloud supreme and this feels pretty close at a fraction of the price. Oh yes , that's the other feature i LOVE: the price! Even my husband,who is a great skeptic, about buying a mattress on line was and is impressed by this bed. One of the best purchases ever. One word of caution though when you first get it let it air out over night before you sleep in it. We slept in it the first night and woke up with major headaches. After that first night though no problems and no smell."
