I absolutely love my new hybrid mattress it is my primary sleep location. It offers just the right amount of firmness while still allowing the mattress to slightly form to your body while you sleep.  This hybrid mattress does not give you that sunken feeling that I have experienced with other foam mattresses. I am typically a cold sleeper and I have also noticed that I am not waking up throughout the night having to add or remove layers to control the temperature while I sleep.
