Potential problems with split layers in Latex layer beds

First off thanks to all on this board.  I have been looking to purchase a latex bed for quite some time now, and I almost pulled the trigger on a Sealy model that was made of (mostly) latex.  Now that I know a lot more, I am getting really into the details and this forum helps me a lot.

I've been looking at the split layers (one firmness side for each person) and zoned systems (head to toe firmness differences) and I am curious if any of you can share any insight.  My questions are below:

1)  For the different firmness for each person, the latex needs to be split into two pieces - left side and right side.  Are there problems with one edge rubbing up against the other edge and creating a bump in the middle of the bed?  Any other potential issues?  Or does it seem to work without any issues.

2)  Does having three layers (stacked on top of each other) cause any issues as well, such as shifting, rubbing, etc etc?  Does it matter if I have to put the soft side on the bottom (If the exhange period is over and I need a firmer bed for instance)?

3)  Does anyone have any experience with the zones (diffenrent firmness from head to toe) and is it worth it at all?  Meaning is it just another gimmick or does it really make a difference.

4)  Would stacking Dunlop on bottom and Talalay on top help for a larger person because Dunlop is more dense and might prevent bottoming out?  This question is not for me but I maybe recommending latex for somebody.

Any thoughts (regardless of if you have actual experience) would be helpful.

Thanks in advance.  I have alot more questions but I'll post separately.

1) I have had my 100% latex bed for over three months and have never once felt a ridge.  My bed is from Flobeds, and over the split layers there is a single layer topper that covers the entire bed.
2) I have never experienced this shifting or rubbing.  Latex is pretty clingy, so I think it would be difficult to have this problem.  I don't know about putting the softer side on the bottom, generally you need the firm layers at the bottom.  You should be able to find out what you need and do your exchanges within the three month exchange period (if you're going the Flobed route - can't speak to other company's exchange policies).
3) My mattress isn't zoned.
4) I am a large person and I have more than adequate support with an all Talalay mattress, with extra firm layers (currently I have F (32 ILD) over XF (36 ILD) over XF (36 ILD).

Another positive for the zoning system - good to hear.  Conceptually it seems intuitive - our middle of our body weighs the most so we need the most support - just not sure if it's really worth the added cost (not to mention the time to really get it right).  I am having some back problems right now due to my worn out mattress and I don't mind spending the extra money if it will make a difference.

Also another post saying teh potential for the split layers to create ridges seems to be non issue.  This is off topic, but does anybody know how many U.S. manufactures there are (both Talalay and Dunlop)?  Just asking because it seems all Talalay is Latex International.  No imports or other brands as far as I've seen.  I am of the impression that there are good quality as well (as opposed to other imported brands, where you are not sure).

Thanks again for your input - I feel a little better making a decision now.

I don't remember Kimberly do you have a Queen size?  If so do you have different ILDs on each side?  Next question is 1/2 of a queen size (30" wide) enough room to have separate firmness sides to sleep on.  Hope you understand my question, LOL.

I talked to Arizona Premium mattress company and they told me their blended latex (not 100% natural) comes from the netherlands, while their 100% all natural talalay comes from Latex International.

My hesitation with Flobeds, arizona, etc  is the idea of buying a bunch of foam layers and having it hold up as a mattress for a long time, just inside a zippered cover. Anyone else concerned about that? Where are you getting yours--Flobeds?

I'm not sure I understand your question. "Just inside a zippered cover" What do you mean?

All mattresses manufactured are just inside of a cover. All of big S. brands mattresses are just inside a cover. On their innerspring models it's true that they may attach their cheap PU foam to the springs, but it is still, "just inside a cover"

The cover that I have from FloBeds is a top quality cover. I have never seen them, but there have been no reports from other board members regarding the other manufacturers of latex mattresses that their covers do not hold up. It very well could be true that the covers will not last as long as the natural latex, as it is reputed to have anywhere from 20 to 50 year life expectancy.

I just got rid of a soft sided waterbed when I purchased my FloBeds 100% natural latex mattress. I had it for 10 years. The liner had a rip in it, but the main problem was the anti-floatation material in the bladder had broken loose and piled up on one side. But the cover, and it was a zippered top cover, was in great shape. What is wearing out is the mattress topper that I had on the waterbed, that I'm now using on my latex bed.

If I'm understanding your question correctly, you are not understanding how a latex mattress is constructed, and the quality of materials used in it.

 Hi Leo,

Yes, mine is a queen size.  And yes, there are two sides to the bed.  One side is F/XF/XF (currently my side) and the other side is XF/XF/XF (hubby's side).  Yes, a Queen is big enough for each of you to have separate firmnesses.

Further, when I sneak over to hubby's side for cuddling & what not, I don't really feel a significant difference when I "cross the line."  I dont' feel a ridge or separation at all, just a slight firming up of the mattress.

That's interesting information!

I don't see the zippered mattress cover as being any different, really, than a completely sealed mattress.  The latex layers are heavy, and "grippy".  They won't move once encased,  in fact if they were not in a cover at all I don't think they'd move either.

Also, latex has a pretty long longevity record - regularly hear reports of people who have had theirs for 20 years or more and still going strong.

My zippered FloBed mattress cover is high quality. It is no different than the covers on the mattresses that are sewed on the edges and not zippered. I love knowing what is inside my mattress and to be able to adjust the layers to my comfort level.

I believe you would find a lot of people on this forum, if they were to buy a big "S" brand innerspring mattress, that they would prefer to have a totally zippered top cover. That way, when the cheap PU foam began to break down, they could simply unzip the top, take out the old broken down foam, and replace it with some decent latex.

These mattress covers utilized by the various online latex mattress manufactures, are of high quality and designed to allow the customer to make the decisions they want about there beds configuration.

There's no way these big "S" mattress companies would add a zipper - You'd be too grossed out by what you find inside.
