I don't recall anyone else referring to latex in terms of 4.75lb or 5.3 lb density.

Is this legit? They're describing it in memory foam terms!

$209 for a twin x 2" topper is not that great of a price though imho.  RockyMountainMattress has 2" of natural talalay for $170 with free shipping for a limited time (they've had free shipping for many months, now...)

However, they do not have latex in 16-18IFD (or ILD).

• "4.75 pound density w/ 16-18 IFD"

Actually RMM does list it this way.    http://www.rockymountainmattress.com/latextopper-p-45.html

Apparently this is how Latex Green describes their latex?

What is IFD instead of ILD?

I know it is frustrating when companies who have web sites don't answer emails in a timely manner or not at all. I'm like, "Okay, if you don't want to answer emails, then why put an email address or email form on your site??" But in RMM's defense, when I called them I got right through and the man on the other end was very helpful. 1-866-733-3132

Funny I didn't notice that RMM uses the same term! Yeah, maybe it's a latex green thing. Where's Budgy?

As to  "what is IFD":

----------------------------------

wikipedia:

IFD stands for Idealization-Frustration-Demoralization. The term was coined by semanticist Wendell Johnson (1906-1965) and has been re-popularized by modern psychologists and self-help writers. Johnson, also a consulting psychologist, believed that IFD disease was the most common malady that kept people from achieving happiness or contentment.

The basic idea behind IFD is that most of us live in a mental landscape of abstract absolutes—ideals. We set vague goals for ourselves such as “I want to be happy”, “I want to be a success”, or “I want to be in love.” These phrases are absolutes, not very good for appropriate goal-setting, and they are what begin the IFD process. In the world of absolutes, you’re either ‘happy’ or you’re not, a ‘success’ or a failure. And how do you know which one you are if you have nothing but a vague idea to identify it with?

Once we are in the IFD cycle, we encounter:

• Idealization: We compare what is present in our reality to a picture we’re holding in our mind.
• Frustration: Reality doesn’t match up to how we think things should be.
• Demoralization: Judgment is passed on what is, and the object of frustration is stripped of worth.

Something happens as a setback to our plans, and we suddenly feel like the whole thing is a bust, a complete waste of time. Then, eventually, after going through a wave of negative emotions we either move to a new situation or change our mind about the current situation, and the entire IFD cycle starts over again.

--------------------------------------

Just kidding. I knew basically what IFD was but wanted to use the exact term so I did a google and found this. Thought it was interesting, though totally off-topic! ;-D Basically, for all practical purposes, IFD and ILD are the same.

When referring to foam, IFD is similar to ILD, but is used more, it seems, with pu foam and memory foam whereas latex seems to use ILD more. Budgy, feel free to correct me... I'm just talking from my experience of reading about foam on the web...

Eagle2 posted a long post about ILD vs. Density or something like that a few months ago which probably has an even better explanation. But...

---------------------------------------

This is wikipedia re IFD as concerns memory foam:  http://en.wikipedia.org/wiki/Memory_foam

"The property of firmness (hard to soft) of memory foam is used in determining comfort. Firmness is measured by a foam's indentation force deflection (IFD) rating. However, it is not an accurate measure on "soft" and "firm". A higher IFD foam, with a lower density can feel soft when compressed.

IFD measures the force (in pounds-force) required to make a dent 1 inch into a foam sample 15" x 15" x 4" by an 8-inch diameter (50 sq in) disc—known as IFD @ 25% compression. IFD ratings for memory foams range between super soft (IFD 10) and semi-rigid (IFD 12). Most memory foam mattresses are firm (IFD 12 to IFD 16).

Some report that IFD is a poor way to measure softness of memory foam, and that foam density as a measure of quality is more important, but not always true.^[2] Foam density of 5 pounds per cubic foot (80 kg/m³) or greater is considered high quality, although most standard memory foam has a density of 1 to 5 lb/ft³ (16–80 kg/m³). Most bedding, such as topper pads and comfort layers in mattresses is 3 to 4.5 lb/ft³."

More than you wanted to know? Probably.

Hmmm. I found this which says it's the same as ILD but I thought it was a bit different than ILD. Otherwise, why have two different terms? Budgy?

-----------------------------------
From: http://vitalityweb.com/backstore/ILD-ratings.htm  :

"I.L.D., " Indentation load deflection", is measured by putting a 15"X15"X4" specimen of foam in an indentometer and measuring the weight required to push the foam down to 25%, 65% and back to 25% of its thickness. Therefore, an I.L.D. rating of 10 lbs. at 25% means that it takes 10 lbs. to compress the foam 25%, 65% I.L.D. compresses the foam 65% and will have a higher figure, then it is brought back to 25% and this is generally the right I.L.D. rating. These days I.F.D, "Indentation force deflection", is sometimes used instead of ILD but means the same thing."

Okay thanks IFD is ILD.  Budgy, paging Budgy....  Does Latex Green rate their latex by pound?  Is it really accurate?  Is the 16-18 IFD LG dunlop really much firmer than talalay natural?  From RMM website "The dense latex provides superior support, and is ideal for heavier sleepers who do not receive adequate support from less springy memory foam toppers". It doesn't say that for Talalay natural.  I am thinking it might be what I need.   I am not lightweight like some people here  .

I too get peeved with people who don't answer emails, especially businesses.

I have two very small businesses - haven't made any $ with either one yet! - but I check those email boxes twice a day just in case! I even check one site for my friend who has a business because I noted that he was slow so we have an arrangement where he compensates me for checking it for him and forwarding anything I find to his main mail address! So I do think there is no good excuse for not answering emails directed to one's business!

RMM latex green price for queen is $209, ACOS is $279; this is a 2" topper.

Who else sells Latex Green toppers?

Don't know who else sells latex green. SleepEZ does, don't they?

Is it worth the extra $70 to get a return privilege? That's a tough choice. Maybe it is if you think there's a fair chance you'll want to return it. Of course you will have to pay shipping on it which is probably going to be around $50. And be careful when you unpack it so you can repack it into the same box and bag. So if you return it you will have paid an extra $120. Is it worth it? Or better to just keep the foam and use it on a guest bed or whatever...? It's a tough choice...

IFD = ILD basically.  Just different terminology.  The density on latex is not commonly spec'd out...
