What I learned at the Healthy Back store and Spindle vs. Brooklyn Bedding questions

Hi malus.rex,

I would keep in mind that there is really no need for a local retailer or manufacturer to release “comfort specs” such as ILD to their customers because with careful and objective testing your body will tell you what you need to know about the suitability of a mattress in terms of PPP (Posture and alignment, Pressure relief, and Personal preferences). Comfort specs have little to nothing to do with the quality of the materials and “quality specs” are what a “transparent” manufacturer or retailer should be able to provide you. They are well aware that customers that are looking for ILD or other “comfort” information are most likely trying to “duplicate” their mattresses (which are often unique to them) elsewhere … and will often be unsuccessful because they only use ILD and really don’t have enough knowledge or experience to take the other specs of mattress materials or components into account. To match one mattress to another you would need to use the same type and thickness of every layer or component and use a very similar cover (see post #9 here about trying to match one mattress to another).

Having said that … there are some manufacturers that do provide “comfort specs” or ILD information and if there is a local PLB dealer near you (they have a retail store finder here) you can see the specs of their mattresses here which may provide a useful reference point.

I would keep in mind that the Healthy Back mattresses may have different specs from the Pure Latex Bliss. They most closely approximate either version 1 or version 2 of the Bliss line (which you can see here) but while the layer thicknesses may be the same … the ILD’s may be different.

The PLB Pamper uses 40 ILD for the core and the others use 36 ILD. The Peace is an old model that used synthetic Dunlop and I’ve never seen any ILD information about it. The top layer of the old Peace was firmer (28 ILD) than the old Pamper (19 ILD) but Healthy Back uses Celsion in their comfort layers (now called Talalay GL fast response) which comes in a different range of ILD’s than the blended Talalay that was used in the old PLB line.

Latex doesn’t come in specific ILD’s and is always in a range (see post #6 here). Spindle gives you a choice between mostly synthetic Dunlop (like the base layer in the Peace) which is much less costly and 100% natural Dunlop. Both use a continuous pour method which produces a more consistent ILD range than molded Dunlop but in their case their latex has 7 zones so there would be different ILD’s in each zone (Note: Spindle is now only using 100% natural continuous pour Dunlop in their mattresses). I would also keep in mind that Mountaintop foam that makes their latex also measures ILD a little differently than Latex International so they may not be exact matches although Neal has a good idea of which ILD’s would likely be a reasonable match.

I would keep in mind that they use a more costly version of latex than the mostly synthetic latex used in the Spindle lower budget line (Note: Spindle is now only using 100% natural continuous pour Dunlop in their mattresses). I would also consider that both of them are very different designs from either the Healthy Back Peace or Serenity so you would be using approximations and “best judgement” about which of the versions offered by either Spindle or Brooklyn Bedding would be most likely to be a rough equivalent of either of the Healthy Back mattresses.

I would think so yes and the 2.17 lb polyfoam base layer isn’t likely to be a significant factor in the longevity or durability of the mattress with 6" of latex over it (a mattress will usually soften and break down from the top down).

Again … with a 3" latex comfort layer … it would be difficult to “translate” the ILD that would feel most equivalent to the Peace for your body type or sleeping style especially if there is no ILD information available to you for the Dunlop core so you may need to make a “best guess” based on subjective perceptions and then leave any fine tuning up to your personal experience and a possible layer exchange. Once again … layer thickness will make as much difference as layer ILD and with a 1" comfort layer a big part of what you feel will be the synthetic Dunlop core of the Peace.

They are certainly great value but their lower cost line is mostly synthetic Dunlop which is a much lower cost material than either blended Talalay or 100% natural Dunlop (including their own 100% natural Dunlop). There may also be differences in the covers they use which can also be a significant part of the cost of a mattress. There is more about the different types and blends of latex in post #6 here.

There is really no way to know this with any certainty outside of your own personal experience because it would depend on how all the layers of each mattress interacted with each other and the cover and with you in terms of PPP but you can see a more generic comparison between an all latex mattress and a latex/polyfoam hybrid in post #2 here.

It would certainly be reasonable to expect 10 years of “support” for this mattress for most people of your weight yes but it would also depend on the suitability of your comfort choice and where in your range of comfort and support it was and how much “room” you had for foam softening (see post #2 here).

You are certainly looking at some very good options to make a final choice.
