I guess I'm trying to achieve zoning by "cheating" -- that is, without actually cutting up any of these nice full slabs of latex that I've shelled out some dough for. (The 2" piece was $272, which is not exactly small change for me.) I have not tried toppers with the zoning built in, but that's certainly an option down the road if I can't figure out another way.

It is unfortunate that we apparently still can't quite count on FBM's latex to be exactly as it's advertised on their website. Could still be worth a shot. I might try adding a piece of scrap foam, just under my hips, first, only because that'd be cheaper, and I can find other uses for the scrap if that experiment doesn't work.

About the 32ILD piece from SLAB -- it might well be suitable for a middle layer or a just-below-the-comfort-layer layer.

I mentioned above that if I put the 24ILD piece on the floor, fold it over (so it's 2" thick), and lie on it, on my side, my hips and shoulders go right down to the floor. To get some comparison data, I just put the 32ILD piece (2") on the floor and lay on that.

When I lay on it on my side, it was surprisingly comfortable. I definitely did not bottom out. The only uncomfy thing was that my shoulders needed a little more cush to sink into, so they felt kinda crunched; my hips, though, were fine.

When I lay on my back on it, I did not sink in much, so I'd still need something more for lumbar support. (That is, the small of my back was not supported because I didn't sink quite far enough into the latex.)

Does that help? I think the latex will feel different depending on what's below it -- floor, innerspring mattress, firmer latex core, whatever -- but that was the only way I could think of to get a direct comparison, since there's no way to quantify how this stuff feels.

Edited to add: I'm back to wondering if I should have ordered a 1" 28ILD and a 1" 32ILD, or even a 2" 28ILD, instead of the 2" 32ILD. I have a couple weeks left in the 30-day return period. Don't quite know how I'd stuff that 2" piece into a box for shipping, but that's an option. Sigh. I'm so confused....

I could ask someone at SLAB for an opinion, but since they were the ones who suggested just 1" of 24ILD two years ago, and that turned out to be seriously inadequate, I'm not sure how much I'd trust their opinion this time around. Couldn't hurt to ask, I s'pose.

I need to do something, 'cause I'm waking up with lower back pain, which I think means that my hips are sinking in too far compared to the rest of me.

Still thinking this through: With just the 3" of latex, my hips are good but shoulders are crunched. With the 3" of latex plus the old fiberbed, my shoulders are good but hips sink too far. So, either I ditch the fiberbed and adjust the latex layers so I get more cushion for the shoulders; or I keep the fiberbed but bolster the hip area.

I hope that makes sense.....

Also... this is why it's better to experiment an inch at a time. I ignored my own guideline when I bought the 2" topper. D'oh!

Couple things ... one is your cover may be causing your shoulder problems. The firm cover may be preventing your shoulders from sinking in. You can get a cotton terry cover from FBM that will be much softer and allow your shoulders some relief. A cheaper cover can be found here:  http://stores.ebay.com/PolySoftProducts?_trksid=p4340.l2563  Order a 3" cover.

Second I would order a 1" 20 ild soft piece of latex from FBM and try it with the terry cover along with the other latex you already have.4" of latex will fit into a 3" cover.  If it doens't work for you you can return it to FBM. The FBM latex is all natural tayalay which in my experience is a little more dense than the blended stuff even at the same ild and offers a lttle but noticeable support - ymmv though. I would be surprised if this didn't work for you. Give it a try! If it still isn't quite enough return the 1" and get a 2" from FBM in soft.

I was wondering about that. There is some give to the cover -- it's not pulled tight, even with 3" of latex in it -- but it is thick, nonstretchy fabric. The terry cover from FBM might be a better option, so I'll keep that in mind.

Because of their prices, I assumed that FBM's latex was blended Talalay. If it's really the all-natural stuff (their website says that it is), I'm curious where they get it and how they can keep their prices so low.

Yesterday I spoke with Evelyn at SleepLikeABear, and she said they've been hammered by price increases from Latex International 3 times already this year, so SLAB has had to raise their prices, too. (Another factor in that, according to Evelyn: LI closed their factory in California, so SLAB has to bring inventory in from Connecticut. Higher shipping costs, I s'pose.)

I really should have called SLAB before ordering my 2" 32ILD topper; I probably would have ordered a 1" 28ILD and 1" 32ILD instead. I think I need gradual transitions between softer and firmer layers. Evelyn mentioned that SLAB rarely has returns from people who order a series of graduated layers like that.

So anyway, I ordered a 1" N3 (equivalent to 25-29 ILD) topper from SLAB, squeaking in just before the rather hefty price increase. (Instead of going the cheap route this time, I decided to try the N3 piece and see if there's a difference in feel and point elasticity between the blended Talalay and the all-natural Talalay.) SLAB expedited the ordering processing for me, so the topper shipped yesterday, and I'll have it on 9/6, which gives me time to experiment with using it both with and without the 32ILD topper below it, before my 30-day return period on the 32ILD topper runs out.

I'm hoping I'm set now, but if I wind up returning the 32ILD SLAB topper, I may try FBM next.

Hope it works out well with the N3. Keep us updated!

The 2" 32 ILD topper was too firm for me, so it went back to SLAB, and I have received notice of the refund. That topper was an expensive mistake; the return shipping fee ate up almost half of my refund. (Heavy topper; very difficult to fold up into a manageable size by myself; had to spend $15 on a box big enough to hold it, 'cause it was still a big bundle of latex even after I'd compressed it as much as I could; and then $75 to ship from NY to CA. Ouch.)

After all that, I finally did what I should have done in the first place, which was to go back to the store where I bought my innerspring mattress, lie on the latex beds they sell, find out what's in 'em, and ask the sales guy if he can have the factory cut a latex topper for me. (The store is owned by Jamestown Mattress, a small independent family-owned business.) Sure, no problem. (Really good price, too. Can't fathom why I didn't think to go there first.)

So now I have, from top to bottom:
- a 2" very soft (14 to 17 ILD) Talalay topper from Jamestown Mattress,
- the 1" 24 ILD topper from SLAB, and
- the 1" N3 (25 to 29 ILD) topper from SLAB.

The top 3" are in the terry-cloth cover from FBM. I tried putting the bottom piece in, but the terry cloth looked like it was stretching too much around the zipper, and I didn't want to risk pulling the thing apart, so that bottom topper is just covered with an ancient sheet to protect it from the nubbies on the bottom of the FBM cover.

I'm hoping that I'm done mucking around with latex now and don't have to start messing around with zoning, but we'll see.*

The next thing to figure out is what kind of mattress pad to put over all this.

My really thick baffled pad is pretty flexible, still cushy in the shoulders, but flattened in the hip area, so when I use that, my hips still sink in too far compared to the rest of me, so I wake up with lower back pain. Which puts me right back where I started. Took that cover off, for now.

The past two nights, I used only my old cotton-covered polyfill mattress pad. First morning I woke up with slightly numb hands & arms; this morning, woke up with numb hands & arms and incredibly sore shoulders, so that pad has got to go. It's clearly too stiff and defeating the purpose of having the soft latex. Argh.

My understanding -- someone correct me if I'm wrong -- is that the latex needs to be protected from moisture. I don't want any kind of mattress protector with a membrane -- they tend not to be breathable -- so I think that leaves wool. The wool might be great for regulating temperature and keeping dust mites at bay.

The very kind owner of Laughlin Designs (www.snuggledown.com) is sending me a fabric sample of the St. Dormeir wool & terry mattress cover. (As far as I know, there are no local stores that carry the Dormeir.) I know the sides of the cover will be stretchy enough, but I'm not sure if the top is stretchy enough to let the soft latex conform to me. 

Dang. Who knew that creating a comfy bed could get so complicated... and expensive....

-------

* Edited to add: Well, I just took off the old mattress pad and lay on the topper stack on my bed for a few minutes. Being right over the latex (with the terry cover) is better, but there is still not quite enough cushion for the shoulders.

So, I will need to mess around with zoning, or add an inch of memory foam to the stack. (Or just get another cheap polyfill fiberbed, knowing that I'll have to replace it when it compresses.) Phooey.  I was soooo close.

I went back to the store where I bought my mattress and ordered another inch of the super-soft latex. Should have it by the end of next week. That will give me 3" of soft latex, total, to put over the medium latex. If the 3" of soft still isn't enough for my shoulders, then I will use that new 1" piece of soft latex and the 1" piece of 24 ILD latex for zoning. (I'll double the soft stuff up under my shoulders & torso, and double the medium stuff up under my hips to prevent them from sinking in too far.)

Also, I received the fabric sample for the St. Dormeir wool mattress pad from Laughlin Designs, and decided to order the mattress pad. I think it will be stretchy enough not to affect the latex.

I'll update again when I've got everything put together.

(I've been experimenting for a couple of months, so this is gonna get long and might be a little disjointed.)

I have tried every possible permutation of the layering materials I have, and tried some zoning, and have yet to find anything that works as a comfort layer on top of my innerspring mattress.


Here are the latex layers I had (not necessarily all used at the same time) before I tried the zoning:

• 2" 14-17 ILD natural Talalay latex, bought from a local mattress manufacturer (I'll refer to this piece as 14 ILD; it is ridiculously soft, & quite fragile)
• 1" 14 ILD, from the same vendor
• 1" 24 ILD Talatech, bought from SleepLikeaBear in 2009 (still holding up well)
• 1" N3 (25-29 ILD) natural Talalay from SleepLikeaBear (flawless)

I also have an old thing that I've been calling a fiberbed but which was sold as an extra-thick (1") mattress pad, bought on sale at Kohl's 5-6 years ago. It held up for quite a few years but is getting too compressed to be much use now, and the softer latex was meant to replace it.

No combination of these materials worked -- and I tried them all -- so, on to the zoning.

First attempt at zoning:
I tried to do it artificially, without cutting up expensive latex or buying more of it. It almost worked -- and was certainly worth a try. I used a 5mm thick 24" wide yoga mat under my hips. The yoga mat cost all of $13, and I tried it in various locations in the layer stack (and in various permutations of the layer stack).

The difficulty here was that if I had the yoga mat in the right place to prevent my hips from sinking in too far, then it interfered with pressure relief, but if I placed it farther down in the stack to help with pressure relief, then my hips sank that much farther down, throwing my spine out of alignment and causing back pain.

Second attempt at zoning:
I ordered a 1" 32ILD scrap of Talatech from SleepLikeaBear. The scrap was about 30" x 78" (I cut it down to 54" to fit my full-size bed), and flawless. I cut up the 1" piece of 14 ILD latex, and put pieces together to create a layer that was 14 ILD for the first 30" (head & most of torso); 32 ILD for the next 30" (lower lumbar region, hips, thighs) and 14 ILD for the last 15".

I tried using that zoned layer in various places within various permutations of the layering stack (still using it for now, actually), but I didn’t get it quite right.

I think that (a) the difference between 14ILD and 32ILD is too extreme; (b) I don't have the right ILDs for either zone; and (c) I'd need more than an inch of zoned topper to get the required effect. That last point is probably obvious, but I was hoping I could get away with one layer of zoned stuff while keeping the rest of the (more expensive) layers intact.

It's possible that I am one of those people who cannot get the proper support from latex. Or maybe I could with different pieces – maybe the 20-22 ILD topper from SleepEZ, or, say, a few inches of 19-20 ILD for the shoulders, and 28 ILD for the hips -- but not with what I have now. Or, I should say, not with what I have that I am willing to cut up. Cutting a whole sheet of expensive, no-seam latex would just make me feel like I'm cutting up dollar bills.

(If I cut the 24 ILD or N3 toppers and still didn't get the zoning right, I'd be pretty mad at myself. Neither of these pieces has any seams; and buying new latex would be very expensive. The 1" 24 ILD piece that cost me $132 in 2009 now costs $216. So I'm not cutting them. If they wind up coming off the bed, they can be used elsewhere, maybe on a guest bed.)  (And yes, FBM stuff is much cheaper, but you never know what you're going to get with their latex. Their covers, on the other hand, are fine.)


Anyway…

I've become convinced that the 14 ILD stuff is just too soft, period. Feels like I'm crashing right through it -- my bony little shoulders go through that stuff like a knife. (I recruited a girlfriend to help me with this, check my alignment, and so on, and she confirmed that my shoulders go right down to the bottom of 3" of the 14ILD latex.)

Now, I know that the point of the softer stuff is that so my shoulders *can* sink in -- but I think there's such a thing as sinking too much or too fast... or too... something. And the 14ILD is clearly too soft for use under my hips, with or without zoning. I finally had to take the top 2" of soft latex off the bed because the sinking-in was killing my back and exacerbating my hip pain. (I don't typically have back pain, unless it's caused by my bed or by doing too much yard work.)

I've also concluded that even really soft latex, when it's solid, does not conform quite enough for someone like me -- i.e., side-sleeper with a pronounced hourglass shape. Having roughly a 10" difference between my waist measurement and my shoulder & hip measurements complicates things.

I've been told that this soft latex should be conforming to me, but I still wind up feeling like I'm in some sort of crater, and that just bothers me. Latex certainly doesn't conform the way memory foam would (nor did I expect it to), but I don't like the feel of memory foam, or the heat or the off-gassing from it. My polyfill fiberbed, before it wore out, seemed to conform more than the latex does.

I think the ideal comfort layer would be shredded latex enclosed in a cover with lots of small baffled squares to prevent the latex from shifting. Maybe even a zoned version of this, with softer shredded latex in the shoulder area and medium shredded latex in the hip area. Unfortunately, something like this would be labor-intensive and therefore very expensive to make.

Flobeds sells a shredded-latex topper, but its baffles are long rows, rather than lots of small squares. I could see getting my hips stuck in an area between rows. So that's out.

-------

Throughout this endeavor, every purchase I've made seemed logical at the time, based on what I knew at the time. But I've made some expensive mistakes and still can't figure out how to get both support (proper alignment) and pressure relief from latex. And this stuff is too expensive -- and too tricky -- to keep messing around with. And I don't think I should need physics and engineering degrees just to create a decent comfort layer for my bed.

Along those lines: The advice that is often given on this forum -- buy a firm mattress and then "just" add toppers -- also made sense to me at the time (when I bought my extra-firm mattress in 2009). However...

...there is turning out to be a big huge gap between theory and experience.

Next time, I think I'd still buy an innerspring, but get a comfier one -- not a pillowtop, but a somewhat plush mattress -- and be prepared to do mattress surgery whenever the foam gave out.

(Please note that I'm not blaming the forum; it's generally very helpful and I made my own decisions. The problem is that adding a comfort layer turns out to be anything but simple, at least for a side-sleeper.)

In the meantime, my current innerspring mattress is only 2+ years old and has plenty of life in it, so I still need toppers.

So I've ordered a new fiberbed -- two, actually, both returnable. Obviously, I'm really hoping that one of these things will work, with or without my zoned layer underneath. I'll let y'all know.

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

There is one piece of good news here: I'm really liking the St. Dormeir wool mattress protector. It is surprisingly stretchy, so it doesn't interfere with the toppers, and it seems to help with temperature regulation, at least so far (in fall & winter). So I highly recommend it.


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

One last bit, in case anyone's interested: I did a bunch of floor testing with the various layers, trying to isolate variables. In the list of results below, when I say "bottom out," I mean that I'm lying on my side, and my hips & shoulders compress the latex all the way and go right down to the floor.

The results, in case anyone wants to compare their own builds & experiences:

• 2" 14 ILD latex (solid piece) -- bottom out
• 3" 14 ILD latex (the 2" piece + the 1" inch piece) -- bottom out
• 2" 24 ILD (the 1" piece folded over) -- bottom out
• 3" 14 ILD over 1" 24 ILD -- bottom out
• 1" 14 ILD over 2" 24 ILD -- bottom out
• 2" 14 ILD over 2" 24 ILD -- bottom out
• 2" N3/27 ILD (the 1" piece, folded over) -- bottom out
• 3" N3/27 ILD (1" piece folded in thirds) -- bottom out, or very close to it (that was a surprise)
• 2" 24 ILD over 2" N3/27 ILD (each 1" piece folded over) -- hips were kinda OK with this, but shoulders were still seriously crunched; I'd probably need more 20-24 ILD and less 27 ILD for them
• 1" 32 ILD (the large scrap piece I got from SLAB) -- bottom out
• 2" 32 ILD (the 2" solid topper that I tried out and then returned to SLAB) -- no bottoming out. Not good for pressure relief, but no bottoming out.

In all of these bottoming-out scenarios, it's my shoulders that hurt the most. They seem to need a more gradual transition to firmer layers below, or... something. Damned if I know....

 

I didn't want to order latex without trying it and go through the possible headache of having to return it, so I got a 2" thick fiberbed with small baffles (to keep the filling from shifting) to put on my new, way-too-firm bed, then under it I put a cheap egg crate foam slab from Walmart. This combination turned my bed into comfort heaven for me  - so soft and comfy but still supportive for my midsection. I suffered a back injury last year and have gotten up stiff and painful every morning, but since I put this bed together this summer, I have no pain whatsoever!

Hope you hit on the magic combination as well.

...trying to isolate variables."

You're not going to want to hear this idea, since you know the mattress itself, as-is, could not be among the confounding variables, but I went through exactly what you describe & then some, assuming there'd be some ultimate combination of foam I could add that would make it right.  It wasn't until I extracted my inersprings, leaving nothing between them & my latex, did all the layer swapping & buying/returning foams end.

 That junction between spring & foam is a huge potential weak spot.  Just like how having too much of anything between yourself & your top layer can rob latex of its conforming properties, inersprings can be hamstrung by their own foam & casing.  You still want the springs' action to transmit through & work with that of the foam's to some degree, and that never happened buried inside a mattress I was merely piling on top of.  If you were just down to the springs, assuming they're of sufficient coil type & count, I'd bet any of your layers would work.  Then it wouldn't feel so much like bottoming out, but flexing into & working with your springs.  It's just hard to abandon all the nice mattress pads & encasements, & even harder to cut into a mattress, but I've done it twice now, & am convinced a mattress' comfort layers must be entirely replaced, not just added to.
