Instead of replacing your mattress

I have a Serta hybrid (mashup of pillow top and memory foam) mattress that was so comfortable I used to like down and feel like I was floating. All my life I've been a back sleeper who lies still and doesn't toss and turn. That is, until a year or so ago. Lately it seemed like I could never find a comfortable position. I thought I was starting to have lower back issues but didn't suspect the mattress because it's only 6 yrs old. Then I saw this mattress topper and decided to try it. It has made a huge difference! I can sleep through the night again. Based on other observations I think my mattress had gotten compressed. So if you're thinking you need to replace your mattress, try this instead. It's way cheaper and you don't have to deal with the hassle of hauling or disposing of your mattress. It comes with a carrying case so you could even use it for car camping.
