Thanks for your updates !
[quote]Beautyrest Recharge Bainbridge Pillowtop Firm Queen, approximately 7 years old
Your Beautyrest Recharge Bainbridge Pillowtop Firm/ Queen is a 13.5" gel memory foam innerspring mattress, designed with a firm comfort feel. Thanks for sharing that detail, as well as both of your personal stats, these help with understanding a bit of your sleep situation details.
I strongly recommend that if you have access to COVID-safe showrooms and are comfortable doing so to make the time for mattress testing and comparisons when you can. As it has been several days since your post, you may have some updates on that front.
[quote]I am currently in the progress of building it out. Here’s what I have so far from bottom to top.
• 1/2 Polyfoam
• 6" QE Elite Coils
• 3" Sleep on Latex Medium (ILD 34 - Dunlop?)[/quote]
Good work on the support base of your build, Andy ! The 1/2" polyfoam base layer will serve to stabilize the 6" QEE pocket coil unit, you’ll want to follow Phoenix’s suggestion and use anHD polyfoam with a minimum 1.5- 1.8 lbs. per cu. ft. density for higher durability. Are you going with QEE Bolsa coils or QEE Combi-zone coils?
The setup as described above (coils + polyfoam= base) is your support system; in this construction, the 3" dunlop latex/ 34 ILD becomes a transition layer instead; is this what you mean when referring to it as “support latex”? In other words, support comes from coil unit below, and any added materials become part of the comfort feel of the mattress. 34 ILD is generally a fairly firm feel for dunlop latex, so not sure whether the coil unit isn’t supportive enough or that you prefer a firmer feeling latex.
[quote]I am quite confused about the ILD ratings of Sleep on Latex vs Latex Factory, etc. The ILD’s of Sleep on Latex are much higher. Also, i am uncertain if SOL sells dunlop or talalay. @Sensei, what ILD dunlop layer would you suggest for me and what size - 2" vs 3"?
ILDs will vary somewhat among manufacturers and is generally expressed in an accepted range within the mattress industry, this Phoenix graphic depicts commonly used ranges:
FYI, SOL uses Dunlop/ Natural latex in their mattresses and toppers. A 2" dunlop layer should work well for you both, in perhaps a medium-soft ILD range, depending on your response to the questions above on the support build.
The 1/2" polyfoam layer over the coils isn’t necessary and wouldn’t serve the same purpose as the 1/2" layer beneath the coils. Unless you prefer a 3" layer that is firmer than your 34 ILD dunlop layer over the coils, an additional 3" firm layer isn’t needed, only the one 3" layer of the correct firmness would be fine.
A 2" 19 ILD Talalay layer could be too soft for your preferences, Andy. The addition of a 1" memory foam layer over it may “deaden” the Talalay’s plush feel somewhat. If you want more of a “sleeping on” the bed feel, the Talalay layer should be the topmost layer to get the full benefit of it’s naturally conforming, pressure-relieving qualities. But again, the type materials used and how they are layered are part of your personal preferences. Use of the highest quality materials will ensure the most durable, long-lasting mattress possible.
Any updates on your DIY? Looking forward to hearing more about your progress and good luck .
