Hi PBR,
Thanks for posting your question on The Mattress Underground site. I will try and address your questions with general knowledge of the industry; I am not completely familiar with all that Denver Mattress uses in their beds.
1). On the Doctors Choice Elite Firm, is there a problem with the 1" Anti-Microbial Super Soft EF Foam in the quilt layer? They don't state the density here. It's only 1", so it seems to be not a big deal, but I also believe I've read that Eggshell Foam is not a good material for durability? Is EF foam a lower grade foam to be worried about?
They say their top panel is made up using the following:
Quilt Layers:
Double Knit Ticking
1 1/2" of 1.8lb Density Convoluted EF Foam
1" EF Foam
Natural Rayon Fire Barrier
Their 1 1/2" of 1.8 Density quilt foam is a good product....right up until they convolute it. That takes away from the integrity and the quality. You will see that as you go up in price with the three models you have asked about, they no longer contain convoluted foam.
EF Foam is Earth Friendly foam from Denver Mattress. That means that their foam manufacturer use a natural oil that displaces a portion of the Polyol in the formulation. It plays to their marketing more than their quality. They didn't tell us the firmness of this foam.
The quilt pattern is a large continuous pattern that lends itself to firmer mattresses.
Their Comfort layers State:
Comfort Layers:
2 1/2" of 1.8lb Density Convoluted EF Foam
Again they don't tell us the firmness of the foam and they have convoluted what is there, challenging the long term integrity of the foam.
The Marshall Coil support springs have the 14.5 gauge wires which are a medium firm individual pocketed coil spring.
The next mattress Uses their B.O.S.S.® (Balanced Orthopedic Sleep System) Spring; and I have to say there is not a lot of material online about this spring. We do know it is a pocketed coil because the springs are individually wrapped, and this will be similar in feel to the Madison due to the gauge of wire used. The difference is the "Checkerboard" configuration of the springs. Does that mean they are alternating? I'm not really sure. I think a call to Denver Mattress will provide the needed explanation.
The quilt layers:
Quilt layers:
Luxurious Knit Ticking
1" Anti-Microbial Super Soft EF Foam
1/2" Anti-Microbial 1.8lb High Density EF Foam
Inherent Rayon Fire Barrier
The Super Soft foam will be comfortable, but they don't tell the density. This layering seems okay for a firm mattress.
Comfort Layers:
1" 4lb Gel/Visco Memory Foam
1" 2lb High Density Luxury Firm EF Foam
Having 1" of the 4 lb Gel and 2 pound firm EF foam seems good for this bed. The Gel will add softness, and if they are using over a 50 IFD on the EF foam, it will provide good support, however they don't tell us that.
You notice that there is no convoluted foam in this mattress; in fact, there is not a lot of foam at all in this mattress.
The final mattress you mention is the Richmond - also the most expensive.
Comfort Layers:
3" 2.5lb
Serene
™ Comfort Foam
This is a patented foam from Carpenter. I don't have direct experience with this foam, but 3" of any type of memory foam is too thick in my opinion.
They put this on top of their B.O.S.S.® (Balanced Orthopedic Sleep System) Spring and then put it all on 4" of 1.8 pound base foam with some sort of strategic cut outs for air flow. Again, not a lot online showing this configuration, but something a phone call or visit to Denver Mattress can explain.
Finally, you say
(from online google search) The Boss system (Balanced Orthopaedic Spring System) provides 7 zone support, helps assist in body alignment as you sleep and minimises partner disturbance by reducing sideways movement giving you a more restful night's sleep.
However, that is the definition of the Australian company Sleepyhead. They call their
BOSS
spring system - Balanced Orthopaedic Spring System
and Denver Mattress says, BALANCED ORTHOPEDIC SLEEP SYSTEM.
The Sleepyhead spring is an offset coil system, and Denver Mattress says theirs is an individually wrapped Marshall Coil spring. So I am not confident these are the same springs.
I hope this helps you when reviewing the three mattresses. The best thing is to actually go into a showroom and let the RSA fit you to a bed that you find comfortable and supportive. If you are not near a Denver Mattress showroom, then a conversation over the phone and they can hopefully send you pictures of their spring system, their Engineered Articulating Cuts and provide IFD's for the foam they are using.
Sincerely,
Debbie Lewis
