Hi Jgo,
I've re-listed the specs to exclude the information I don't need and to list the specifics of all the layers of the mattress from top to bottom along with some comments.
Here's what I think I know based on the specs you listed ...
Kodiak Plush:
Cover: Cool Max® Fabric which is fine.
1 1/2" 1.5 lb Polyfoam quilted to the cover: This would be "acceptable" if there were no other lower quality foams in the top layers.
.5" 2.5 lb VLS Visco Lumbar Support: this is beginning to take the total amount of lower density foams over the edge although it is a belly band which is only in part of the mattress.
2" High Density convoluted 1.8 lb foam insert: This is at the bottom end of "good quality" polyfoam and the convoluting would make it a little less durable than a solid layer of the same density.
6" 704 Marshall “Zoned” “Pocketed” Foam Encased Coil w/ 3" x 6" High Density Firm Encasement Rails: It would be nice to know the gauge of the coils in each zone although this isn't likely to be the weak link of the mattress. The foam encasement is very firm (60 ILD) but is also lower density than I would like to see (1.5 lb density) so this isn't a mattress where I would spend a lot of time sitting on the edge ... especially with higher weights.
2" base support pad: This is used to support the coils and it would also be nice to know the density of this layer but it's also less "essential" because it's on the bottom of the mattress.
Total layers 11.5" (excluding visco support layer and the effect of the quilting) which adds up to the thickness of the mattress so all the layers are listed
I normally use a guideline of "about an inch or so" of lower quality or unknown materials in the upper layers of a mattress and this one has 2" (the quilting polyfoam and the visco) which is why I would want to know the density of both layers. That plus the fact that the 1.8 lb polyfoam insert is convoluted which is less durable than solid layers adds some risk to the mattress in terms of foam softening and breakdown over time. Assuming that the unknown layers are good quality materials ... these are better quality materials than most "mainstream" mattresses but I would make some careful quality comparisons with other mattresses in the same price range. This would probably be fine for average body weights but may be on the low side for higher body weights.
Bronze Emerald (or more likely the Sapphire):
Tissue Pick Damask Fabric: This is fine
3/4" firm 1.5 lb polyfoam quilted to the cover: This in combination with the .5" Visco Lumbar Support is in the range of about an inch or so of unknown materials so while it would be nice to know the density it isn't absolutely necessary.
1/2" 2.5 lb VLS Visco Lumbar Support: See comments above
2" 1.8 lb High Density convoluted foam insert: This again is at the bottom end of "good quality" polyfoam and the convoluting would make it a little less durable than a solid layer.
3/4" Comfort support layer pad: I would want to know what type of material this is.
1/4" insulator pad: This is fine
Spring barrier: This is probably fine although they don't say what type of material it is.
7" 644 Ameri Spring w/ Ameri Guard (Steel Encased) continous coil: They don't mention the coil gauge but this is a continuous coil which would generally provide firm even support but be less contouring and less costly than the pocket coil in the Kodiak. I would make sure that you are OK with the motion isolation of this mattress because of the continuous coil. Steel edge supports are stronger than polyfoam edge supports. I would also guess that this mattress would be quite different from the Kodiak in terms of PPP.
After excluding the .5" visco which is only in the middle of the mattress (and wasn't included in the total for the previous mattress) the total layers are 10.75" which is less than the total 13" thickness (not 11.5") of the Bronze Emerald that they mention on their
site here
. It appears that these may be the specs of the Bronze Sapphire which is 11.5" and the difference between the listed layers and the 11.5" thickness is probably the spring barrier.
This is a lower budget mattress that may not be as "comfortable" as the Kodiak and I would make sure you test it carefully for PPP but my comments about the quality of the foam above the innerspring would be similar to the Kodiak.
I would choose both of these over most mainstream mattresses but I would make some good comparisons with other mattresses that are available to you because they are "on the line" in terms of quality/durability (most mainstream mattresses are well below the line) and I would be cautious with higher than average body weights.
