I decided to make all the beds in my house adjustable ones, so I have different brands and functions to compare. This is my favorite. I like the appearance of a solid surface, although that doesn't seem to make any difference in performance. The two outstanding functions are the "Zero Gravity" preset and the "Massage". Sure, you can fiddle with the controls until you reach something that feels like zero gravity, but nothing compares to being able to merely press a button to get that feature. If you have back problems, like me, the zero gravity is sometimes the only way to get relief. The other feature, the massage, is surprisingly pleasant. It's gentle and can be adjusted to several modes. 
All the adjustable beds need almost no assembly; just unfold the base, scoot it beside your existing bed and slide your mattress onto the new base. But this base has features that you won't want to be without!
