Hi sleepaholic,
[quote]1 inch of traditional inner spring (855 coils)
2.5 inch of micro coils (which he said was pretty much pocketed coils).
1 in of polyurethane
2 inches of natural latex (they had their own unique marketing name for the latex but he did say it was a natural latex).[/quote]
I think there may have been something lost in the translation here. If the innerspring is a “traditional” innerspring then it would be thicker than 1". If it was only 1" it would be a microcoil like the 2.5" microcoil you listed but it’s unlikely that there would be two microcoils in the mattress. The mattress components that you listed would need to add up to the thickness of the mattress and the components you listed would make a mattress that was only 6.5" tall.
Microcoils are a type of pocket coil that uses lower gauge steel that is softer and they are generally used as comfort layers to replace foam materials instead of as a support system like “traditional” pocket coils. They are a good quality and durable component. You can read more about them in this article and in post #8 here and post #2 here.
If you can confirm the specs of the mattress (and confirm that they add up to the thickness of the mattress) and post them on the forum then I’d certainly be happy to make some comments about the quality and durability of the materials and components and the mattress as a whole.
I would also want to know the type of latex (either Talalay or Dunlop) so you can make more meaningful comparisons with other mattresses.
