Hi Phoenix,

The plot thickens...

It seems that breathability is going to be an issue with the wool topper. Shepherd's dream was not too enthusiastic about my idea of putting the 3" Snuggle Mate over a eco high density 6" foam base in a Murphy bed. I've consulted the Murphy bed seller (StilDesign) for ideas. I don't actually have the bed yet. I've put down a 50% deposit - and the bed is still a good idea for my bedroom-office.

The bed has a very shallow steel frame, something like the attached photo, except queen size

Or this...

www.showerking.com/murphy-beds.php

The bed's one-piece foot swings up to hold the mattress in place when the bed is to be put away.

Shepherd's Dream has a pricey insert which might work:

www.shepherdsdream.ca/product-info/custom-box-insert/

Or perhaps something from Ikea like you discuss here:

www.themattressunderground.com/mattress-forum/general-mattresses/1740-ikea-sultan-laxeby-slatted-base.html

I can likely pick up one of those second hand (and assembled) for cheap.

What are BE outlets? Are they in Canada?

Then there's still the question of buying a base layer. Shepherd's Dream has these latex slats.

www.shepherdsdream.ca/product-info/latex-padded-slats/

I'd love to get a wool mattress (vs topper) but they're expensive and may not stand up in a Murphy bed anyway (?).

Comfort wise, I prefer wool to the latex (any ILD). MF is comfy but too toxic.

Thanks,

Michael

Hi Miko,

It seems that breathability is going to be an issue with the wool topper.


I'm not sure why breathability would be an issue (wool is very breathable) but my bigger concerns would be trying a combination I wasn't familiar with in terms of comfort (wool over polyfoam could become quite firm depending on the firmness of the polyfoam and the specifics of the topper) and on the topper "flopping around" as the bed was raised and lowered and possibly becoming damaged in the mechanism or shifting the wool over time. If I had a murphy bed (see post #64 here ) I would probably tend towards a "finished mattress" that I had tested with a stiff base layer that would stand up to longer periods of time on edge where the risk of shifting or sagging layers was minimized and the manufacturer confirmed that it would work well inside the murphy bed.

The ideal would be that the murphy bed was suitable for supporting a mattress by itself without a foundation at all but if it isn't (I can't see the details of the support surface on your murphy bed) then you would need a foundation as well. If you do need a foundation I would tend to use a low profile foundation because you are limited to 11" in height and you won't need a foundation with the narrower gaps that would be necessary for a mattress with a latex base. A base with flexible slats or tension adjustable slats (like the Laxeby) could either help or detract from the feel and performance of your mattress depending on the thickness of the mattress and on the specifics of the combination. Your highest odds are to test a mattress that works well on a firm non flexing foundation and then to use something similar under the mattress (either the murphy bed itself or a foundation if it needs one) so you don't have another variable to try and "match" the characteristics of a flexible base that you haven't tested in combination with the mattress.

What are BE outlets? Are they in Canada?


BE is Berkeley Ergonomics and at this point they don't have any retailers in Canada. NOTE ADDED: they are now available at www.tmasc.ca/store/sfnt.html who are one of the members of this site and will ship across the country.


Overall I would tend to focus on a mattress that I was familiar with the combination of materials (through personal testing or at least using similar material combinations to those I had tested) and didn't have a tendency to shift or sag.

Hi Phoenix,

Happy Fourth of July!

Your advice on getting a "finished" mattress for my Murphy bed sounds sensible. As discussed, my maximum height is 11". I may reconsider an inner spring/coil core (vs. polyfoam). I'm not sure why I went to semi eco-friendly polyfoam core in the first place.

To recap on top layers, I love the feel of gel-infused memory foam, but I'm concerned about VOCs. Latex (any ILD) is not working for me (too bouncy, "resting on top of the bed" feel). I like wool a lot based on my experience with my 1.5 inch topper, though I take your point about compression.

The top layers (especially jammed/squished shoulders) seems to be my main problem - though I know all the layers work in concert.

This is a bit extreme, but I came across Black Sheep Mattress co. (Calgary) on the internet and spoke to the owner (Christian)

blacksheepmattress.com/

Very knowledgeable and impressive. All natural materials, custom made mattresses. Christian spoke to me about creating a hybrid Devon/Suffolk (see website) in my price range: Top side (soft), bottom side (firm). He spoke about creating a memory foam feel (approximately) with natural materials. He uses high quality springs as the core.

I presumed that the shipping cost to Montreal would be prohibitive (thousands of kilometers), but apparently he's done it before and shipping would cost me a about $140. - so not that bad.

The big downside is not being able to try the mattress, though if it's a bit firm and well below my mattress height limit, I could add .... a topper!

BTW - Shepherd's Dream says they would take back a Snugglemate (3" wool topper) if it's in mint condition - but (as we know) a topper goes against the "finished mattress" idea.

And so it goes...

Got to pull the trigger soon - I'm losing sleep!

I think that polyfoam is less ecofriendly than recycled steel so from that perspective there would be little reason to choose polyfoam.

To recap on top layers, I love the feel of gel-infused memory foam, but I'm concerned about VOCs. Latex (any ILD) is not working for me (too bouncy, "resting on top of the bed" feel). I like wool a lot based on my experience with my 1.5 inch topper, though I take your point about compression.


The real challenge is not so much knowing how a single material works for you but how a combination of materials feels and performs.

For most people, VOC's with polyfoam or memory foam are not a significant issue if it's made in North America or is CeriPur certified but for a smaller percentage of the population who are more sensitive, who purchase a mattress with "faulty" foam, or who for other reasons have come to believe that any type of polyurethane materials are "bad" or "toxic" (memory foam, polyfoam, gel memory foam) regardless of where it is made or any certification then of course they would need to look in other directions. It really depends on how each person answers the question "how safe is safe enough for me?" or "what is the degree or risk I am comfortable with?". This can lead down a rabbit hole of conflicting, incomplete, and very complex information that in many cases is talking about parts per billion of dozens of chemicals with hundreds or variations that may each need to be researched individually to decide on the level of exposure to each that you are comfortable with or which set of numbers (content amounts, VOC amounts, and limits of exposure that different "authorities" consider to be "safe") you decide is most believable because in most cases VOC's and chemical exposures are more about how much you are exposed to from many sources than about eliminating them completely. This can often require a degree in chemistry to really understand to the level where it becomes meaningful or fully relevant.

The top layers (especially jammed/squished shoulders) seems to be my main problem - though I know all the layers work in concert.


This is a typical issue for side sleeping men especially where the broader lighter shoulders (compared to the pelvis) need to be "allowed" sink into the top materials enough to relieve pressure and allow for good upper body alignment while at the same time "stopping" the heavier pelvis from sinking down too far. In more difficult circumstances (more athletic builds) then zoning can make a difference where there are different degrees of firmness under each area of the body.

This is a bit extreme, but I came across Black Sheep Mattress co. (Calgary) on the internet and spoke to the owner (Christian)

blacksheepmattress.com/

Very knowledgeable and impressive. All natural materials, custom made mattresses. Christian spoke to me about creating a hybrid Devon/Suffolk (see website) in my price range: Top side (soft), bottom side (firm). He spoke about creating a memory foam feel (approximately) with natural materials. He uses high quality springs as the core.


They certainly would be a fair value choice and they do use high quality materials with no "weak links" although they are a little on the costly side (Bonnell coils are typically good quality and strong but among the least costly types of innersprings while natural fibers and latex are more costly materials). The challenge here would be choosing the design that would match your needs and preferences and with all online purchases that you can't test in person, then the recourse you have if you make a mistake may be an important part of your personal value equation . Some people equate the "feel" of a wool topper to memory foam and in many cases a wool topper can reduce the springiness of latex and creates a "combination" of the feel of both materials.

The big downside is not being able to try the mattress, though if it's a bit firm and well below my mattress height limit, I could add .... a topper!


A topper is always a good backup option if you choose a mattress that is too firm but of course choosing a suitable topper without trying the combination first can be almost as challenging as choosing a mattress and it's usually "safer" to work towards an initial combination where there is only one choice involved rather than "going in" with the idea of adding a topper. Of course a topper with a Murphy bed has its own risks although a mattress protector with fitted corners may work to keep it in place.

I think if you don't have the chance to test a mattress in person then your confidence that you are making the most suitable choice (based on personal testing on similar mattress and more detailed discussions with the manufacturer) will play a key role in your decision along with the customization, exchange, or return options you have available after a purchase if your choice isn't as close to your ideal as you hoped.

Hi Phoenix,

Well - the deed is done.

I went with a mattress from Stéphane at Matelas Selection in Montreal, basically because I could try the various layers out in person here. If I lived in Calgary, I'd be at Black Sheep's door.

The details...

Base: I went with a 5 inch 2.7 per cu. ft. density "eco-foam" which has one channeled side and one solid side. They are going to "zone" it for me, putting the channeled (more flexible) side up for the shoulders (and feet) and the solid side up for my pelvis area. I can flip it (head to foot) now and then to reduce wear on the shoulder end. This allows my shoulders to sink in a bit more.

It looks quite eco-friendly (as foams go)
www.eupen.com/foam/certificates/index.html

I may have preferred springs (for eco-reasons). He did have a 7.5 pocket spring base, but this would reduce my top layer options (my Murphy bed limit is 11"). It also felt quite a bit harder than the foam base.

The top layer is 2" of soft Talalay latex (not sure what the ILD is).

I tried the combination with my (double size) 1.5" wool topper as is and folded over (to create a 3" topper) and it felt quite good. I may get the 3" queen size Snuggle Mate, if I find I need it.

There is also the option of adding another comfort layer later on, if I need it. I almost went with a 1" layer of 4.25 per cu. ft. blue open-cell Italian gel above the latex, but I thought I would try it as is (when it doubt, go a bit firm...).

The base, latex layer and wool/cotton cover cost me $964. CDN. before taxes. There is good exchange policy.

Finding the mattress took a lot longer than I expected it would, but I feel reasonably sure I'm in the ballpark comfort and eco-wise.

I really appreciate the time you took with my situation, Phoenix. So much good information. I'll update you, if I make any changes.

Best Wishes,

Miko (a.k.a. Michael)

Hi Miko (Michael),

I like the idea of having a softer shoulder zone and it's also very uncommon to see a high quality polyfoam that is also Oeko-Tex certified which is generally a step above CertiPur certification.

It sounds to me like you made a great choice in terms of materials, design, quality, and value and you also have good options if you need them.

I appreciate your feedback on the forum ... it will be valuable for others that are in your area.

Most of all ... Congratulations on your new mattress :)

Hi Phoenix,

I thought I was done, but no such luck. Luckily, I have exchange options.

My custom foam mattress (5" high density eco-foam, 2" latex + my 1.5" wool topper) kept buckling and slipping over the 3" steel Murphy bed frame. The pelvic area sagged some and I was perspiring greatly in the head and shoulders area, probably because my shoulders were happily sinking into the latex.

The seller gave me two options:

Glue a 1" layer of firm foam on the bottom of my existing foam composite mattress. This would bring my mattress height to 9 1/2". My maximum mattress height for the Murphy bed is 11". I'm still worried about the heat and I have my doubts that this altered mattress would stay in the frame. From another seller:

My second (probably preferred) option is to go with a spring mattress (see below). I'm hoping that it will breathe more. I could still use my wool topper.

Any advice?

Thanks (again),

Michael

Hi Miko,

I have no direct experience with Murphy beds so I would not be the best source of advice.

In cases like this ... my "best advice" is to encourage you to talk with several people who are more knowledgeable about Murphy beds which are usually the manufacturers who make them and talk to them about the specifics of your situation. While many mattress manufacturers would have some experience with Murphy beds ... all Murphy bed manufacturers would have a great deal of experience with how different mattresses perform on their beds. This is what I did in post #64 here as an example because in areas where I have little specific knowledge I always talk to people who are more knowledgeable than I am.

You will find some conflicting advice and opinions even when you talk with "experts" who have different experiences but when you do this you will also find some consistent "themes" which will help you make more informed "best judgement" decisions.

Logic says to me that an innerspring mattress is stiffer and less floppy than a mattress that has a foam core and would probably do better on a Murphy bed than a more "floppy" mattress.

I can see from your comments that you've probably read this but for the benefit of others that read this post #2 here talks in more detail about the many interacting factors that in combination can affect the sleeping temperature of a mattress for those who are looking to "cool down" their mattress.

Hi Phoenix,

The consensus is in - and it seems that sprongs (that's springs - I hope there are no sprongs) are the best option for Murphy beds, so I'll go with that. And the spring mattress in question seems to have built in zoning (longer springs under hips area).
