Mattress Forum

When I spoke with Shawn yesterday he talked about how it takes days or even weeks to acclimate to latex and new mattresses in general. He spoke of how your body creates depressions in your mattress that are unique to your body and it takes an adjustment period to readjust to latex. Well, if this is what he means by adjustment I want no part of it. I travel quite a bit and sleep on different mattresses all the time (never any latex though). I have slept on boats, planes, cars, trains, floors and even on the ground. I never wake up unable to walk upright. In fact, I cannot recall ever having acute pain caused by a mattress. Some stiffness maybe but not this, Someting is clearly wrong here.

This was so painful for me that in the middle of the night I crawled out of bed and hopped into my daughter's bed (she is away at school). She has a decent quality inner spring mattress which I have never slept on before. My pain began to dissipate almost immediately - still hurts but clearly something in the latex is causing my back grief.

As I lay in bed unable to sleep it occurred to me that the biggest difference between the latex and a convnetional mattress is rigidity. People here talk quite a bit about firmness and softness but not about rigidity. If I were able to hold a conventional mattress from one end it would have enough rigidity keep from touching the floor. Latex I suspect would be flacid and droop right down to the floor. It seems that the rigid layer of a conventional mattress is close to my back whereas in the latex it is 10" lower down at the base of the bed. My theory is that this is the root of my problem. As a stomach sleeper I need that support up close to my back were it can provide the needed support. I have always gravitated toward firm sleeping surfaces and now I know why. 

It is hard to think about yet another night on the latex mattress but I may try to find a piece of plywood to put under the XF layer to see if this helps. This would bring the support I need up closer to my back. It makes me wonder though about why I spent so much money on 10" of latex if I only end using the top 3". I may give my back a night or 2 of rest (I am exhausted) but will report back with any new thoughts as I progress through this nightmare.

There must be other stomach slepers out there that have gone through this process. Tell me what works. I am all ears. Can a stomach sleeper find success with latex or should I return this mattress and look elsewhere?

Sorry if I seem cranky. Just tired and frustrated.

I tend to agree with you that if it is causing severe pain, then it is not just a matter of taking time to adjust.

 However, I think you are probably using a bad configuration for you.   It seems that you need something pretty firm, so having the soft on the bottom and probably the medium in the middle is not great.  It is possible that you need 2 layers of XF and one a bit softer.   Only some trial and error will tell.  I recall some Flobed people using 3 layers of XF (36 ILD) with the softer 2" convoluted layer on top.

You may want to have him send you an XF and another F layer, so you have more choices.   If your wife can sleep on your spare bed, you may want to swap out the soft for her firm to see if that helps things at all.

I would note that some people end up just not liking an all latex mattress.  You may be one of those, but I would say that it is too early to tell until you try something much firmer.

p.s.  As a temporary measure you may want to try just 6" using the XF & M.  The bed will be unbalanced of course, but your side will be firmer.

p.s.s.  If you really want firm support, you can also consider getting dunlop instead of talalay for 1 or 2 of the support layers.  I see that sleepez XF is 44 ILD.  That is pretty firm stuff for most people. 

The "rigidity" you are talking about in a "normal" mattress comes from the innerspring and is a side effect of how it is constructed and what it is made of ... not from it's softness or firmness. Much of this "rigidity" comes from the steel border rod (which is why an innerspring is constructed differently for use on an adjustable bed so it can "bend"). Even the "softest" innerspring would be more rigid than either latex foam or the layers of foam above the innerspring in a standard mattress even though it may be softer and "less suitable" for someone in actual use than a very firm foam. This "rigid" layer is also at the bottom of a mattress and usually has a non rigid layer of foam (sometimes a quite thick layer of foam) above it. It is the firmness or softness of an innerspring and it's spring rate that determines what it does in the mattress construction ... much like firm foam which is (usually) also in the bottom layer like an innerspring so when they are both flat ... rigidity does not come into play. There are good videos of a "typical" mattress construction and innerspring construction here

Most of the standard mattresses ... even the firmest ones ... have some very soft foam above the firmer layers. This is usually even softer than the softest 14 ILD laex you can buy. Most people have no idea that they are often sleeping on top of very soft foam when they lay on a very firm mattress because the mattress feels so firm. In your case ... how far you are sinking down into the mattress and the thickness of the upper layers (the comfort layer) is a very important issue. The pillow under your hips may solve your issue while you are "fixing" the construction.

I believe that the 8500 would have been more suitable for you as the upper layer would have been only 1.5" of soft and this could have been on top of 2 layers of firm or extra firm ... much more like a traditional "firm" mattress. With 3x3" with even medium on top you may still sink down too far and with say 3 layers of Xfirm or even with a firm on top you may end up with pressure issues as you may need a thin soft layer on top just like a "regular" mattress. Given how light your wife is the 8500 may also work fine for her (she probably doesn't need a really thick comfort layer because of her weight and could have softer foam than you under it to make up for any additional "cradling" she may need).

I also agree with sandman that an Xfirm under medium is the most likely "short term" solution to your problem (besides the pillow).

If I was in your shoes ... I would either consider a topper on top of xfirm or firm layers under or consider switching to the 8500.

On a side note, I found out I am wheat/gluten/yeast intolerant. During the week that I eliminated those foods from my diet, I had no back pain. None. Need to get back on that bandwagon but it's tough.

Have you tried S/F/S? Or even S/S/F? You might be surprised...

Someone had asked what my bed base was composed of (Sandman perhaps?). We have a Euro style bed with 1" x 4" maple slats spaced at 3" intervals. Shawn said that this was fine. I suspect that they flex a little bit at my weight (150 lbs) but probably not enough to be causing the problems that I am having. Just to be sure I'll have my wife take a look when I lie on the bed.

More next week...

 XF/M should be a good experiment, but that may not have a lot of depth.  If that seems close, then you probably want to add another XF on the bottom to use XF/XF/M.   If you really want just a firm 3" base, get the XF in dunlop.

I don't know if you tried F/XF/M.  That should be slightly firmer than XF/F/M.

p.s.  I think stomach sleepers are the hardest to get right.  As Phoenix noted, you maybe need an extra support under you hip area.  Maybe a pillow or a 1" firm piece of foam to put under that area.
