Hi Dave88LX,
It certainly is very useful … thanks 
I would tend to avoid the Embrace Energy because of the lower density foams in the comfort layer and would stick with the other two which use medium density or better quality materials.
I would also make some careful value comparisons with both the Embrace Comfort and the Embrace Relaxation as well because they both use lower density foam than is available in other mattresses in their price range and design and there may be some better value options available for mattresses that have a similar design and materials. Of course a significant part of “value” is the feel and performance of a mattress in terms of PPP and there are also other parts of each person’s personal value equation that may also be an important part of any purchase decision but they would need to be significantly better in some quantifiable way to justify their more premium prices compared to other similar mattresses.
