Hi timinswfl,
Thanks for posting the specs for both the mattresses you listed. You are the first one I’ve seen that was able to find them
Signature Elite 1:
8 oz safeguard Fibers: this is the fire barrier.
1" 1.5 lb polyfoam 10 ILD: This is soft polyfoam used in the quilting and if that’s all the polyfoam there was in the comfort layers it would be within the guidelines I normally use for lower quality polyfoam (under 1.8 lbs) in the comfort layers. If other layers put the total of lower density polyfoam in the upper layers to 2" or more then I would be very cautious in terms of durability.
1" - 2" 60K 19 ILD latex: This isn’t clear whether there are two layers that total 1" or if there are two 1" layers (totalling 2") but I believe it would be a total of 2". They also don’t mention the type or blend of the latex (which I would want to know) but it would be a good quality material. Based on the comment of “with holes” then it may be a Dunlop supplied by Latexco (who punches holes in their Continuous pour Dunlop as an option after it is poured) but this is only speculation.
7/8" 1.45 lb polyfoam 18 IFD: This puts the total of lower density polyfoam over 2" and even though this is lower in the mattress and under the latex which would inprove it’s durability … it is still well within the depth of compression for most people where it’s durability in combination with the layers above it would be an issue
1 1/4" 1.45 lb polyfoam 23 IFD: Same comments as the layer above. This for me would clearly put it over the line of a mattress I would be comfortable with and would only consider in a one sided mattress in a low budget range. It is certainly not suitable for a premium mattress.
2.8" 60K Latex with 6" foam side rails: Same comments as the latex in the upper layer except the polyfoam side rails used for edge support are much more likely to break down than the latex and are a cost cutting and design feature that I would prefer not to have (I would use firmer latex for edge support if you choose to use it on a latex layer so it will have the same durability). By the time you reach this layer of the mattress then there is already too much lower density polyfoam in the layers above it to have any reasonable expectation of good durability.
3.5" x 2.5" x 2 layers = 7" of 1.8 lb convoluted polyfoam: The 3.5 is the peak height and the 2.5" is the valley height of the convolute. While convoluted polyfoam is less durable than non convoluted … I would still consider this to be a suitable base layer but this wouldn’t be nearly as important in terms of durability as the layers above it.
For a mattress in this price range … I would certainly avoid it.
Signature Elite 2: This has exactly the same type of foam layers except some of them are firmer so would be more durable to some degree but this mattress would still be much too risky with this much polyfoam of this density in the upper layers.
Overall both of these have 3 1/8" of lower density polyfoam in the top cushioning layers which is more than the guideline I would use of “around an inch or so” in total) and would certainly be a “weak link” in the mattress. In a budget range which is more costly than many all latex mattresses … I certainly wouldn’t consider them.
Thanks so much for adding this information to the forum as a reference for others that may be considering any of the Dr Breus line.
