I have had this for about two months now.  It feels like one side is MUCH than the other.  If I lay on that side, I constantly feel like I am going to roll right off the bed.  Since I sleep in this bed alone, it is not a big deal because I can sleep in the middle or on the other side.  I have flipped the mattress and it really does not help.

I was worried the bed would be too hot, but it is OK.

I bought a "Wayfair Basics Metal Box Spring" and a "Kaniel Button Tufted Upholstered Platform Bed" from Wayfair along with this mattress.  The mattress, box spring, and bed frame are all different lengths and widths making the mattress hang over the edge of the box spring and creating a slight gap in the bed frame.  Very inconsistent. 

In short, you get what you pay for.
