mattress help---pillow top

We are onto our 4th mattress in 5 years....the first one we bought was pretty expensive...had to be replaced in less than 6 months because it was sagging...replaced it with the exact same mattress...and the same thing happened...but they wouldn't replace it because it was 1/8th of an inch not sagging enough So then I bought a mattress from Costco because it seemed cool...you can adjust it because it had air mattress type things..and foam on top of it...but it sux. We've had it a little over a year, and are done...

Any suggestions? All we need is the mattress, we have the box spring. Thanks!
