We did alot of researching for a new mattress.  I'm 58 and a side sleeper and husband is 59 back sleeper.  So had trouble finding something that would help us both.  While no serious back issues we are at an age where the aches and pains are bothering us at night.  We were hesitant on the price of the wave hybrid but as my son pointed out - put good money into anything between you and the ground, thats tires, shoes, and mattress.  Prior to the wave hybrid we were both waking up multiple times a night.  Since the new mattress we are both sleeping through the night and wake up much more refreshed.  Oh yes, the dogs love it too.
