Mattress sags and loses support after 2-3 months

I was so excited to bring this mattress home and use it. After 2 - 3 months, it lost it's support and I woke up with more back pain than I went to sleep with! The seller replaced it without any difficulty, HOWEVER- it did the same thing after 2 months! Where I sleep is like a deep depression, and to get to the other side of the bed is like rolling uphill 2 inches! I am so disappointed, especially since I paid $2,600.00 for this mattress. The retailer is replacing it again this week, but I am not hopeful that the issues will not reoccur.
