I loved it the first couple nights.  After that I noticed I had to switch sides for it to go back up to firmness.  With a couple it’s just not feasible to switch sides every night.  I did tell customer service about this because I thought it may have just been the mattress, until I started sleeping on the other side of the bed and it did the same thing.  A few nights it takes to go back to original.  I would love to give this 5 stars if it would stay firm  or go back to firmness after getting out of bed.
