I've been looking for the good mattress over the last two weeks. I'm 4'11" and weight 270 lbs. I was wondering which mattress would be best for me a very firm bed with a latex topper ( the latex topper can be changed out) or would a sterns and foster latex mattress hold up for 10 yrs. I tried one sterns and foster latex pillow top for $2969 on sale in a queen size. I tried a sterns and fosters trisha luxury firm . for $1700. it was okay. I'm hearding a lot of bad things about mattress. I'm hearing that most don't last very long any tips or suggestions?
