My husband has had both a neck and lower back fusion.  Right now he sleeps in a recliner most of the time as he can only lay in our bed for about four hours before the pain is too much.  Currently we have a seven inch firm latex matress in a waterbed frame with two foam toppers.  One is 3 inch 3.3 pound viscoelastic memory foam topper and a 2 inch foamex resilitex medium.  We went looking at mattresses and the one so far that seemed most comfortable to him is the Tempur Pedic Bella Sonna because it seemed to feel the best on his pressure points.  However the price is really up there for that mattress. Is there anything out there such as different toppers that we could use to get the same effect the the Bella Sonna? 

Thank you for your help,
