Hi Sheepcounter,
The good news about your mattress is that if you only paid $600 (and I don’t know how that would be possible for the mattress you linked if it was new) then at least it would be reasonable value even if it only lasts you for a few years and if it lasts you longer it would be a bonus.

The pillow thread here and the information it links to should be helpful
