My husband and I purchased this mattress in a king size with an adjustable base. Though we sleep in different positions, we’ve both been blown away by the deep sleep we’re able to achieve in this bed! (such a marked difference from our last one!) I’m also now able to lounge in bed long after waking because my back and hips don’t hurt. (I used to have to jump out of bed as soon as I woke up because I couldn’t get comfortable again.) It’s been a wonderful 2+ weeks.
