Hello TMU!

Looking for a bit of guidance and advice. I've done quite a bit of reading elsewhere and then found this site and feel like I've found the real, uunbiased information I had been looking for all along.
Here is a bit about the sleepers and some background:
Me: 5'11" 195lbs. 41 years old. 100% side sleeper. I've been waking up with soreness in my hips and I do have some lower back problems which essentially come down to arthritis (facet disease & degenerative disc disease). My wife likes to call me the "Prince and the Pea" because it has traditionally been difficult for me to find a quality, long-lasting mattress.
Wife: 5'6" 160lbs 40 years old. 80% side sleeper 20% back sleeper. No significant issues and much less fussy when it comes to mattress selection.
The best mattress I have had to date is a Dormeo 5500, which I purchased from Sleep Country about 6 years ago. When I first bought it I had never slept better in my life, but last year after we moved we decided to get a new mattress, and boy did we make a big mistake. We didn't want to get anything very expensive, so I bought a Sleep In Mattress "Bella" model, which was recommended to me at a local furniture store. It's a hybrid which they say is "foam encased with gel". Sufficed to say it's not meeting our needs after just over a year since we bought it, so now we are doing a lot more research and trying to find something that will satisfy those PPPs and be durable enough to last enough at least 5 years.

From all the research I've done so far, I have landed on latex, and from there have decided we are going to take a look at Dormio and Foamite since they are both relatively close to us and seem to be well reviewed on the site here. We went to Dormio in Mississauga today, and spoke with a friendly, patient, and well-versed salesperson named Lance. There was no pressure whatsoever, and he gladly answered any questions we had. After testing 6-8 different models we finally settled on 2 that we thought were contenders:

The Emerald ($3898): 6" firm - 3" soft - 2" LGU
Sunshine 11 ($3898): 3" firm - 3" firm - 3" medium - 2" soft

And then in terms of density, he gave me the following information:
Firm = 90 K/m3
Medium = 75 K/m3
Soft = 65 K/m3
LGU = 55 K/m3

It seems that Dormio has a sister brand called Sunshine Mattress Co. Not really sure of their actual affiliation, but they only have 2 models, which are an 8" and an 11" profile. We were able to try the "firm" and "medium" feel, but they only have the "soft" feel at their showroom on Dufferin in Toronto. We may book another appointment there in order to try all the versions.

We are planning to go to Foamite on Tuesday and see what they are offering. One thing I like about them is that they supply foam for many of the bigger and smaller mattress companies around, so I figure they should be absolute experts on the subject. I will post again after we have been there, and I'm not sure exactly what kind of guidance or recommendations one can make from the information I've provided, but any input would be greatly appreciated.

Thank you very much!

Alright. So here is the update:

We went to Foamite and I've got to say the experience was quite different and a lot more reassuring than Dormio. We spoke with Bob who was incredibly knowledgable and answered all of our questions to the fullest extent. Overall, the word that keeps coming to mind is "transparent" and that is not just about Bob, but also quite literally as they have foam just about everywhere in the showroom, including a massive display of dozens of different types of foam near the front desk. I guess that's what happens when you deal with an actual foam manufacturer directly. What gave me a lot of peace of mind was not only that Foamite supplies many of the biggest brands in the business, but also that next to each floor model mattress was a cutaway showing you exactly how each one is constructed. That's just how transparent they are with their products.

Through speaking with Bob I began to have a few doubts about my experience at Dormio. First of all, he was unfamiliar with them as a company and also with LGU as a latex material. Since Dormio sells latex mattresses I am very surprised that Foamite wouldn't be aware of them since Foamite is such a large distributor/manufacturer. Then, when I mentioned that Dormio wasn't overly clear about their foam densities, and that they used K/m3 rather than speaking in ILD and lbs/inch2 that also seemed to hit a nerve. So a couple of red flags, but considering these are coming from a competitor, I know I should be taking them with a grain of salt.

Bottom line is that I felt much more confident in the quality and the product that Foamite offers. They base their suggestions and guidance on what they call Ergo Numbers, and this is generally to do with one's weight and sleep style, along with a number of other factors. Not only that, but they will customize the mattress to your specifications. So we can have zoning that allows the mattress to be softer at the shoulders and feet than the hip section, and I can have a different firmness on my side of the mattress as compared to my wife's side if we have different preferences. They also make the mattress double sided so we can have one firmness on one side and a different firmness on the other should we want to switch. I believe there is also the option to just switch the placement of the layers ourselves by unzipping the cover. After trying 3 of their product lines and several firmness options for each, we settled on the following:

10" thick mattress overall
LX26 = medium firmness 100% all natural latex
PR28 = medium firmness high resiliency soy-based bio foam
KN41 = firm firmness Koosh Natural 2.6lb high resiliency foam

Top: LX26 all the way across
My side: PR28 then KN41
Her side: PR28
Firm edges with KN41 all the way around
Latex/C-pkt hybrid with silver pure 2-sided zippered cover

At this point, I am pretty sure about this choice. We are going to go back to Foamite on Tuesday for another test and possibly to purchase. Any insights folks might provide before then would be greatly appreciated.

Thank you!

A couple comments that might help your search.

First the 2 most important characteristics with foam are usually density (helps to understand the durability of the foam over time) and ILD (effectively translates to a pressure or force over a given area at a certain deflection percentage). Some foams like latex don't usually list density because manufacturers are few and durability of the foam is usually very high. Additionally there are different types of latex foam which includes both dunlop and talalay which have very different feel (the more curvy you are the more talalay will likely suit you better as a comfort layer). There is no mention of what type of latex this is so I suspect it's likely dunlop. Poly foams you usually want at least 2.0 lb/ft3 and the higher the better in terms of durability so I would ask about the densities of the other layers (I suspect the foam names indicate their ILD ratings but it would be good to verify this on the data sheets). If the manufacturer is being fully transparent then I would ask for the data sheets on all the foams which should list all the ASTM specs to be able to evaluate the performance of the foam over its lifetime.

I did see this from Foamtite: www.foamite.com/foam-grades/ (I don't see any data sheets though, should specify what ASTM testing was performed)

Here's an example where the datasheets are provided: www.foambymail.com/datasheets.html
