Hi ghiggz.
I was able to dig up the specifications of the Lifetime 3 model from a recent thread.
• ~1.5" inch: Top Quilt: Dupont® Sorona natural fiber
o Partially plant-based polymer
o Breathable of its low water absorption, durable
• 3.5 inch: Natural Latex * Nano Spring Cassette comfort cassette unit for support and luxury with a light-as-a-feather feel.
o Latex layer in cassettes …
Blue: softer 1.5" Talalay 24 ILD
Micro coils in between: .5 sheet of ~5000? micro coils
White: firmer: 1" Talalay 32 ILD
How much is the cassette?:
• 0.75-1" inch: Intermediate support layer, inner tufted to spring unit
o Latex between comfort cassette and spring is tufted
• 8" inch: Powercore 3 Spring unit
o How many: 1000
o Double strength edge, zoned inner coils
Firm tub
14g pocket – tempered steel homemade – firmness
• Inner pocket, individual, compresses only where the body applies weight
• ~0.5" inch: Suspension Layer: Latex, shock absorber for the spring unit, reduces motion transfer, extends durability and
• ~0.5" Inch: Quilted down, like Sorona side panels w/heavy duty handles
The Estate 7000 is has two Talalay latex comfort layers – one firm, one soft – allegedly to give the mattress a “medium feel.” I believe this soft layer is 24 ILD.
There are too many unknowns, variables, and personal preferences involved for me to be able to predict which of these mattresses (or any mattress, really) will be the best match for someone else based on specs (either yours or a mattress). But, when taking in all you know about your sleeping positions and preferences, as well as our Durability Guidelines, it does become easier to make a decision with the mattress specs handy!
Also (and you’ll see me say this to just about everyone, bit of a broken record haha) it is important to have a detailed conversation with whomever you choose to purchase from and provide them with your stats, body type, sleeping styles, general preferences and history, some general information about your current mattress, or what you have tested, and any other specific information or circumstances that could affect your choice of a mattress so they can help you choose which may be your best fit from their inventory.
I hope this helps give you a starting point!
