• My LI core is nominally a 40 but was tested as a 38. LI only says the ILD will be between 38 and 42.

• An ILD 44 core (technically a quarter core) I ordered from FloBeds  felt the same as my 38, and the calculated density was exactly the same, at least hinting that the ILD's are the same. With Talalay latex, ILD varies directly with density, according to some information I have from Latex International, so equal density should mean equal ILD. Note this is NOT true for any other foam.
  

• FoamByMail does offer a 30 day satisfaction guarantee, AND
• It's not like you have an abundance of choices. One would be Mattresses.net. They are a couple hundred dollars more expensive, but they offer a range of ILD's and will do a split left and right if that's of value to you.
  

• I have 1" layers of  ILD 20 and ILD 32, and I really have to use my imagination to feel the difference in firmness. I thought they must both be the same so I called to confirm my order. They insist they sent one 20 and one 32, and the reason they feel so similar is because they are only 1" thick. I really don't know what to make of this. One possibility is the 32 is more like a 30 or even a 28, and maybe the 20 is closer to a 22 or 24. A second possibility is that the difference between a 20 and a 32 is simply not as great as I imagined it would be. Or maybe they really did send me two of the same thing. I just don't know. [Something I have not done is weigh the two. This may or may not shed some light on the situation.]
  

For what it's worth . .

Memory Foam Products covers have a 360 degree zipper.

Foam By Mail covers are only zippered at one end.  Installation is more difficult  . . the cover needs to be turned inside out and pulled back over from one end of the mattress.

Since you may supplement your configuration with additional layers, also consider a wool fleece pad with stretch sides.

Actually I have Foambymail's terry cloth cover and the top completely unzips from the bottom.  My advice is to unzip the top from the bottom, open your new latex mattress on top of the cover's bottom and try and align it as you go.  It is easier than trying to drag/lift your mattress on top of the cover's bottom.  The terry cloth cover is extremely comfortable and easy to use, I highly recommend it.  I squeezed nine inches of latex into it without much of a struggle, I probably would not attempt to do any more than that.

This latex arrived yesterday.  My thoughts are similar to haysdb.  The latex is not quite as nice as talalay from Latex International.  The pores are not as consistent.  However, unlike the sample they mailed to me, the pin core hole structure is consistently spaced, and foam near the edge of the mold is not overly firm.  That I am happy about.  I have no way to measure ILD, but my guess is that I ended up with something higher than 20  It probably isn''t a 32 ILD (which I have 2" of already).  It measures out as a slight trapezoid, which seems normal with latex.  It must be difficult to cut straight lines.  Density seems normal.  The smell is very different from both the blended and natural talalay I have from Latex International.  This foambymail.com latex smells rubbery to me.  There is no sweet vanilla type smell.  It is not overwhelming, but I'm glad it isn't a strong odor, because I think it is not a pleasant odor like the other talalays.

Overall, at this price I think it is worth buying for someone on a budget.

My transaction with foambymail.com was smooth.  They must not be very automated, as it took a few days for them to ship this out.
