my organic sleep experience?

[phoenix]

Hi Brass,

Hi, I ran across a company called my organic sleep and haven’t seen much if anything posted about them here or anywhere else. They seem to be selling 100% natural dunlop (still waiting for a response from them) but not much in the way of selection. Their specs seem a bit off since they’re saying medium 26-28ild is 5.5lb density and their extra firm 38-40 is 6.5lb density. Even for dunlop that seems pretty dense for those ratings. FSF has a chart listing Latex Green’s densities as being much less.

You can see some comments about My Organic Sleep (Myorganicsleep) and some of the other names they use in post #8 here.

Does anyone know what the old single core dunlop mattresses were from back in the 50-60’s? Back then I think people used a lot firmer beds, so likely they might’ve been firmer than I can imagine. I was tossing around the idea of a medium 6" slab as the core and though 26-28 sounds a bit too soft the extra firm is way too firm for my taste.

I don’t know but perhaps someone else that does will see this and be able to answer you. If I remember I’ll ask a few people who may know when I talk with them next to see if they have an idea.

Of the mattresses I tested, the two that felt the best were the PLB nutrition and the savvy serenity 9" dunlop (soft/med/firm). Both of these to me felt a lot firmer than what I’m used to. The PLB pamper felt way too firm to me, I can only assume I was going through the 2" soft top and feeling too much of the 40ild core. The Nutrition uses a slightly softer core and 5" in the top vs 2" but the 28ild directly on top felt pretty firm in terms of surface feel. The difficulty with the serenity is not knowing much about the layers other than general soft/med/firm. They didn’t have a soft/med/med to try, the other side of the bed was firmer yet at med/med/firm. So far I’ve gathered latex is just an all around firmer bed.

You can see the approximate Savvy Rest ILD range in post #2 here. they have since changed Talalay latex suppliers but their ILD range should be approximately the same. Talalay and Dunlop (especially continuous pour Dunlop) can be as low as the low teens in terms of ILD which is a very soft material.

Typically 5" (like in the Nutrition) would end up providing a lot of the support wouldn’t it? Obviously the core plays a role, but most of any “sinking in” (if you could call it that, I doubt I sunk more than an inch laying down on it) would happen along the upper layers and 27ild/19ild 5" thick that didn’t occur (I didn’t dip through those 5" and ‘hit’ the core like I did with the Pamper).

It would be highly unlikely that you are only sinking in an inch. The word “support” can be a little misleading because the goal of a mattress is to keep each person in good alignment in all their sleeping positions which means that some parts of the body need less support so they are “allowed” to sink in more (like the shoulders) and other parts of the body need more support so they can be “stopped” from sinking in too deeply (usually the hips/pelvis) and the more protruding parts of the body also need to sink in enough so that the recessed gaps in the body can be filled in and supported as well. Mattresses that are too firm and mattresses that are too soft can both provide poor support for some parts of the body which can lead to spinal misalignment. There is more in post #6 here that can be helpful to visualize good spinal alignment which is the result of the “right amount” of softer or firmer support under each area of the body. Al the layers will interact together and they will all compress to different degrees and affect all the other layers to different degrees but deeper firmer layers will compress less than softer upper layers.

Taking this into consideration, would a medium dunlop still be risky as a core?

If a Talalay core works well for you in a specific design then the main difference in using a Dunlop core of the same thickness and same firmness in the same design would be in the “feel” of the mattress.

There are too many variables, unknowns and complexities with the rest of your comments and questions to use “theory at a distance” and you will need your personal experience or trial and error to see how they work for you in your “real life” experience.
