I'm thinking of buying a 2" 4 lbs. density "blue" plush memory foam topper from FoamByMail. My question: How much should this weigh in a King size? Are their toppers usually the weight that they state?

And then there is IFD to consider. Sheesh. How is one supposed to know THOSE numbers? They don't usually list that. I realize that density alone isn't what determines softness or firmness. So one topper listed at 4 lbs. can feel different than another one at the same weight density because the IFD might not be the same. How does one know what they're getting then, especially when it's online?

According to FBM website, both 4 and 5 lb have ~14 IFD.  My guess though is that they will feel a bit different. 

Unfortunately, trying is sometimes only way to know which you prefer.  But we are talking about smaller differences.  Most memory foams are soft compared to a firm latex.

@Sandman:

Thank you so much for your reply. In the meantime, Chris at FoamByMail has been graciously answering my questions about their toppers. He said the same thing as you did. All their memory foam toppers are 14 ILD or IFD. He said they feel very similar. The biggest difference is durability between the three densities. He suggested a 3 in h for the best performance if I'm a side sleeper. However, the 2" 3 lbs. Sealy I have seems to be working under the thick CuddleBed fiber mattress cover. It's sitting atop a 1.5 inch firm Omalon topper. The bed is 2 layers of 36 ILD Talalay latex over 1 inch high density poly foam and heavy springs. Since this topper was such a bargain, I might just stick with it and if I feel the need to, order a 4 lbs. density topper from FoamByMail later. Chris was very helpful and I felt like he was giving me the correct information. And, you, too! Thanks again!
