Serta Pure Response vs Natura Solice: HELP!

Hello, I have looked for reviews for these two latex mattresses, but haven't really found any. I am really hoping
somebody has an opinion. Before I give details, let me just mention that  I cannot afford the pure organic mattress from Natura,
so I am aware that the Natura that I am looking at contains some chemicals. In particular,  I am looking at the Ultra-Green Solice.
According to the Natura website, the Solice contains:
  •  Non-removable plush top
  • Bamboo/Cotton blend stretch ticking
  • 18 oz./ yd² Natura Smart Wool in plush top
  • 8" Talalay latex core
  • All natural fire barrier
  • 20 year warranty
Now, today, my husband and I tried out a Serta Pure Response Lavish and Illumination. I gather no one is very happy with the S-brands, but this
bed seemed very comfortable, but I am still concerned about it due to the S-brand reputation.

I know that there is some PU foam in the Serta, but not much. Will this really degrade over time? I am
taking this mattress abroad, so I need it to last a long time.

Any help, advice, anything, would be extemely appreciated. I thank you all in advance!

I'm a little bit confused about what's in and on your mattress. What's in the plush top and how thick is it? Is it the same thing as the topper you're talking about, or something that's attached to the mattress (like a pillowtop) and underneath the topper?

Latex with an ILD of 20-22 will be softer than latex in the 26-32 ILD range. I'm not sure how much of a difference a few points on the ILD scale will make, but it could be worth a try. However, $80 seems like a lot for shipping (to me, anyway) -- does that include the return shipping for the topper that's too firm?  (And if the store is local, why would they charge you for shipping?)

Hi Catherine,

Thanks for your post. I guess my post was a bit confusing. The solice mattress is 10" and is firm. It is solid latex with no pillowtop. I'm not sure what ILD is in the solice mattress. I'm now trying to make the topper softer. The topper is 4", and has 2" of  26-32 ILD talalay latex with 2" of wool. The topper (and mattress) are made by Natura.

I bought the topper through a local store, who is willing to swap the latex part out for a softer latex (NaturaWorld won't do this). The total cost to me for the swap is $80. The local store has to order the new 2" cal king size latex sheet. I didn't expect the store to do the swap for free, and thought the charge was reasonable. No? In any case,  the topper just doesn't feel soft enough. My husband is hurting and not sleeping well, and I also feel that the bed is too hard. I have a bad back, and although my hurt is much less then it was before, I still don't feel like I want to stay in bed when it is time to get up (a sign of total comfort). We both like some cushion. Regardless, it is a much better set up then we had before (a sterns and foster pillowtop). I rather not go the memory foam topper route. But I'll do whatever needs to be done in order to get a comfortable bed!

If my calculations are correct, and you can actually gauge the difference in ILD's in this fashion, then the difference between a piece of latex with an ILD of 22 compared to a piece of latex with an ILD of 32, you would have a difference of 60%. If you do what Latex International does with their ILD numbers and take the middle number in the range that would be from 21 ILD to 29 ILD, or approximately a 40% increase.

Since we are talking in pounds per ILD, then we are talking about a significant difference in feel. I know I can certainly feel a significant difference between a soft piece of International Latex at 22 ILD and a medium piece at 28 ILD.

When you stop to realize that the methodology used to acquire the ILD number, is to take a 4 inch piece of foam compress it 25% of its depth, or 1 inch, and read the number of pounds required to press a ( I believe it's an 8 inch diagonally measured piece of round steel) plate into the foam to this depth, and take a reading. An ILD of 22 would simply mean it took 22 pounds of pressure to squeeze the plate 1 inch into a 4 inch block of foam. I posted a reference to this very convoluted process on another thread. It is quite involved. Believe me it's simpler to just use the numbers given as a general reference point and accept the fact that a soft piece is softer than a medium piece..... and so forth.

But Please, understand this. Not all companies ILD numbers are going to precisely line up with another companies. They will not even line up completely accurately within their own factory. There are just too many intervening variables. So take these numbers as a general ballpark reference point. and so as not to become further confuse understand this also, if you see the reference IFD do not become confused it is basically the same thing as ILD. It is just the newer number and the more accepted number with in that scientific community. ILD stands for "indention load deflection" and IFD stands for "indention force deflection" the reason that I found for this change, has something to do with the metric system. They have simply substituted the word "Force" for the word "Load".That is the only change as far as I know. Other than that, it's beyond me!

It might be reasonable; I don't know. Maybe I'm just cheap.

If you think it's reasonable, go ahead and try it. From what eagle said, it sounds like the 20-22 ILD topper might be enough softer to make a difference and give you the plush feel you're looking for.

If you try the lower ILD topper and the bed still feels too firm, make sure you're not bottoming out on it (pushing the topper down far enough to feel the mattress underneath). That probably won't be a concern, though, with the 2" of latex + 2" of wool. Just a guess. Let us know what you try and what works for you.
