I recently got a Serta 10" queen size mattress with 8" of really firm foam and 2" of gel foam and think I'm going to need a topper. I'm 6'2, 200 lbs and I guess I'm looking for a medium or soft topper. Amazon reviews on budget toppers always seems to show that the toppers around or under $120 only last a few months before bottoming out. I did see people saying to rotate the topper monthly so I guess that would help. I just spent $400 on the mattress so I'm thinking budget, but I could go over $150. I was eyeing a few toppers during the labor day sales, but didn't get one. I'm fine with whatever foam will be soft and reasonably durable. Any suggestions?
