My only experience with memory foam pillows before this was a cheap contour pillow that came with a mattress topper so i was expecting something really soft and mushy. This pillow actually pretty firm, but not in a bad way. it is very comfortable and provides very good support. it conforms well to the neck and head and is also surprisingly very bouncy which i guess why it's called 'high energy'. I sleep on my back back probably 90% of the time, but this pillow is actually kind of high for that since it's so firm. It doesn't sink in too much so i'd probably recommend the low-height version for back and stomach sleepers. for side sleeping though, it is a perfect height for me. overall though very comfortable and a great value. would buy again.
