I wanted to ask if a heavy person needs 4 layers, or if 3 would be enough?  I'd actually like to get the 4-layer (Cal King, split) to have more combos to play with.  But if I choose a 3-layer, would that be enough?

Side sleeper 85%, back sleeper 15%, 440 lbs, one person Cal King...

Also, would a Savvy Rest latex ILD's compare closely with SleepEZ?  I can field test these locally.

Thanks in advance!

Depends on the type and firmness of the latex. 3 layers of firm dunlop would be fine. 3 layers of soft talalay wouldn't be. Best bet is to try it out in the store.

I'm 250 lbs and ordered the 3 layer bed. I added a 1" layer, but more for comfort/softness than anything else (I didn't feel like I was bottoming out). The 1" piece fit in the cover, by the way, so if you start with 3 layers you know you can add at least one more 1" layer.

Sleepez is up front with their latex ILDs: soft (22-24 ILD), medium (30-32 ILD), firm (38-40 ILD), extra firm (44 ILD. This is a little firmer than most other places.

Savvy Rest seems to be playing it a bit closer to the vest. If you can go there, try their beds and see if they will specifically tell you the ILDs. 

OK, so I have decided on a SleepEZ 13,000 (4 layers).  I just field tested a Savvy Rest combo that I think was the most comfortable to me, it was a Firm-D/Med-D/Soft-T.  It even felt a little firm, LOL.  The Firm-D/Med-D/Med-T felt way too firm.  Almost hurt my back when laying on my back.

So my question is, if I ordered a SleepEZ XFirm-D/Frim-D/Med-D/Soft-T (on one side), would that provide enough of a combo to firm up later if I needed to?  For example, later switching the order to perhaps XFirm-D/Firm-D/Soft-T/Med-D?  Or inserting the soft-T anywhere else?

For the other side, I was thinking about the same, but in all Dunlop.

Any input greatly appreciated...

PS  Roughly how long would the adjustment period be to completely adjust to a latex mattress?

I would suggest Dunlop for your weight range, I suspecty it will compress less over the long run.  I would go with as stiff layers for support as you can comfortably tollerate; I think keeping spinal allignment may be more important to you're back health over the long run than short term comfort.  Also as pressure relief may be an issue with stiffer layers, you might go with an inch or two of good quality memory foam or a softer latex topper if that proves to be an issue.  As a heavy guy this is what I found worked.  SleepEz will work with you on trying different layers, but there are associated shipping costs that can add up. 

If I did purchase a XF/F/M/S, and it turned out to be too soft, could I move the soft layer down a layer or two? 

Perhaps changing to a combo such as XF/S/F/M, or XF/F/S/M?  If that would not work, I'll have to re-eval my plan.  But if this would work OK, that would be fantastic!

Thanks folks!

Is it split down the middle, so you can takes pieces off of the other side?  If so, maybe try XF/F/M/M to make it a bit firmer.   Or you have lots of other possiblities beyond that.

If you can't do that, then maybe move the soft down one level first.  So, XF/F/S/M.   See how that works.  If that is pretty close, then maybe you would want to get another medium piece and try that instead of the soft. 

Ultimately you might want to exchange one or 2 pieces for something firmer, but it will take some experimenting to figure that out.
