Hi jovan,
[quote]Phoenix thanks again for your prompt response. What I was talking about is the pictures you shown here: www.themattressunderground.com/mattress-…-pictures.html#24640
When looking the one for the latex myrbacka correct me if I am wrong but the first 6.5" are pure synthetic latex and then the last 2" are the high-resilience polyurethane? I am surprised if is like that. And it seems that there is no other top layer of anything, for example in the dreamfoam case the top layer is not latex but hyper flex foam i wonder is that’s an advantage of disadvantage.[/quote]
The Ikea website doesn’t list the thickness of the synthetic latex layer in the Myrbacka but based on the picture it looks like it’s in the range of about 5.5".
There are many people who prefer the feel of a quilted cover over latex which can have a softer and more “relaxed” feel and there are others that prefer the feel of sleeping more directly on the more resilient latex. There is more about the pros and cons of different types of quilted covers in post #12 here but this is a matter of preference and which one feels and performs better for you.
The deeper layers of a mattress have much less effect on the durability of the mattress than the upper layers of a mattress and the density of a polyfoam support layer has little to do with how a mattress feels or performs but for those that are in higher weight ranges (in about the lower 200 lb range and higher) that would compress the deeper layers “through” the comfort layers more than those that are in lighter weight ranges then the density of the deeper layers can become a bigger factor in the durability and useful life of a mattress. There is more information about the many variables that can affect the durability and useful life of a mattress relative to different people in post #4 here and the posts it links to.
Some people like them a lot and some people don’t like them at all (they find them too bouncy and resilient) but the choice of material in a pillow is even more of a preference choice than it is with mattresses. I am one of the ones that happen to like them (I sleep on a shredded latex pillow). There is more information about choosing a pillow in the pillow topic here that may be useful.
[quote]And once again another change of topic… Did you ever heard of this natural cotton 'futons" with natural latex inside like a sandwish? Please would like to know your opinion. Thanks.
Reference:
I am certainly familiar with the materials they use but I don’t have any personal experience with the specific futon or design. They use 2" of 100% natural and certified organic Dunlop latex in the middle layer and then use organic cotton batting and wool on either side. These are all high quality materials and there would be no weak links in the futon in terms of durability but with a thinner layer of firm Dunlop latex and with natural fibers in the comfort layers that are firmer than most foam materials (and get firmer as they compress over time) it would likely be firmer than the other options you are considering … similar to many other futons.
