Why does nobody warn you that a $350 mattress topper can ruin your back?
I read a post saying a thick foam topper fixes everything, so I got a 4 inch one for my Denver apartment and slept worse than ever. It felt like a marshmallow, and after two weeks my lower back ached every morning. Gave it to my sister and went back to my firm mattress, and the pain stopped in about four days. Has a soft topper ever actually helped anyone here, or is it just a thing people say?
