My old topper was years old and there were tears in it and it was looking dingy.  My mattress has a built in topper so it’s very thick. I have been looking for a comfortable topper that wasn’t bulky but still thick enough it was comfortable. I found It! You can see in the pics it’s large enough to cover the entire bed (not like some that leave gaps along the edges) I can still fit my mattress protector snuggly  over it. My last topper was flat was I was unsure how I’d feel about the egg crate type but I love it. It’s so soft and forms to my body. Also, it’s vacuumed sealed for shipping but once you open it and lay it out it will take its form fairly quickly!
