Hi Phoenix,

Great site - it has been a terrific source of information. I've been into a SavvyRest dealer and tried several combinations of their Serenity mattress layers, and now was hoping to get your advice on what might be our best bet to order at SleepEZ (I know we can exchange layers if needed, but would like to take the best shot the first time). I'm 5'10" 160lbs and a side/back sleeper, and my wife is 5'1" 115lbs and a side/stomach sleeper. I have lower back problems, so have generally found firmer mattresses work better for controlling pain, but also need some cushioning for comfort. The longest period I was back pain free was in a former furnished apartment with a bed that was (I believe) firm dunlop latex... so firm in fact that the first night on it I woke up sore everywhere, so went out and bought a 2" memory foam topper which did the trick. So I guess my questions are:

- How do the SleepEZ and SavvyRest layers compare (e.g. is a medium firmness roughly the same ILD at both)?

- What layering combinations for either SleepEZ's 9000 or 10000 lines would you recommend given the above? At the store I found (top to bottom, all 3" layers) Med (Talalay)/Med (Dunlop)/Firm (Dunlop) seemed to work best, but I wonder whether this is enough support for my lower back and/or whether I'd be better off with a thinner (2") comfort layer. When I tried a Soft/Firm/Firm combination I felt I was sinking too much, while Med/Firm/Firm seemed a bit too hard (though difficult to assess from just a 15min mattress trial).

- My wife can sleep anywhere, and doesn't seem to have an opinion on what was best - given her sleep style, do you think the same layers would work for her?

- Is there a difference in feel/support between the SleepEZ Natural & Organic lines?

Thanks in advance for your help!

Hi anon,

- How do the SleepEZ and SavvyRest layers compare (e.g. is a medium firmness roughly the same ILD at both)?


They would be similar but not necessarily the same. Latex ILD's are not exact and this is especially the case with Dunlop which has a wider ILD range than Talalay. Because of this ... even two different Savvy Rest mattresses with the same ratings may be different from each other. Fortunately ... most people are also not so sensitive to smaller variations in ILD ranges.

You can see the Savvy Rest ILD range for their different materials in post #7 here which have a slightly wider range than the SleepEz ILD range listed on their site. If the layers are the same type of latex and had the same ILD rating ... I think most people (including several forum members who have tried both) would consider them very close.

- What layering combinations for either SleepEZ's 9000 or 10000 lines would you recommend given the above? At the store I found (top to bottom, all 3" layers) Med (Talalay)/Med (Dunlop)/Firm (Dunlop) seemed to work best, but I wonder whether this is enough support for my lower back and/or whether I'd be better off with a thinner (2") comfort layer. When I tried a Soft/Firm/Firm combination I felt I was sinking too much, while Med/Firm/Firm seemed a bit too hard (though difficult to assess from just a 15min mattress trial).


There are some general guidelines for body type here and for sleeping positions here along with the effects of different types of layering here but these are meant more to give you a sense of the different factors involved in making a choice and not as specific suggestions for any individual. For specific suggestions, it's always better to go by your own personal testing results or to talk with the manufacturer directly because they have much more detailed knowledge of the specifics of all the layers, components, and options they have available and how they work together and also have the benefit of a large customer base that they can use as a reference point. In general though ... I would tend towards the same or very similar firmness ratings as you tested even though the soft/medium/firm ratings may be slightly different between different manufacturers or different layers. For most people this would not be an issue.

You can also see a comparison between their covers in post #3 here which would also make a difference.

- Is there a difference in feel/support between the SleepEZ Natural & Organic lines?


the organic line gives you a choice of either organic Dunlop or 100% natural Talalay while the natural line gives you a choice between 100% natural Dunlop and blended Talalay. In any Dunlop layers of the same ILD ... the difference between the 100% natural Dunlop and the organic Dunlop would be negligible and I doubt that anyone could feel a difference.

The difference between 100% natural Talalay and blended Talalay would be less than the difference between Dunlop and Talalay but in a comparison between the same ILD's the blended Talalay would be a little softer, more pressure relieving, and a little less resilient and elastic. In a 2 or 3 inch layer with other layers below it I doubt most people would feel much difference in a blind comparison but comparing mattresses that had say 9" of each type of Talalay, I think that most people would fdeel some difference because of the higher compression modulus (gets firmer faster) and higher resilience and elasticity of the 100% natural Talalay vs the blended version. There will also be some small (but again not that significant in terms of feel) differences between Talalay from different manufacturers.

Hope this helps.

Thanks very much Phoenix for the detailed reply, I will certainly discuss with SleepEZ before ordering.
