Thoughts on Saatva Coil Mattress vs Loom and Leaf Memory Foam Mattress

Hi NYGiants,

1. When you mention that there shouldn’t be more than 1 inch of polyfoam or convoluted foam your are referring to high density foam, low density foam, high residence foam or all of the above?

The guideline is for “no more than about an inch or so” (in the upper layers of the mattress) of lower density polyfoam not polyfoam in general. The single biggest factor in the durability of polyfoam is its density and polyfoam that meets the minimum density requirements in the guidelines can be a durable material. The minimum densities I would suggest for polyfoam (regardless of the type) and memory foam (again regardless of the type) are in post #4 here.

2. Also when referring to no more than 1 inch of polyfoam or convoluted foam…do you mean in the total of all the layers (support layer and comfort layer combined) or do you mean no more than an inch in either layer?

Convoluted foam is less durable than a solid layer of the same material (see post #2 here). With foam layers that are higher density and more durable than the minimum density guidelines then the lowered durability from the convoluting wouldn’t be a significant issue. If there are foam layers that are right at the minimum density that I would suggest then having too much convoluted foam in the upper layers of the mattress (the total of all the layers added up) would be a durability factor even if the density of the polyfoam itself would otherwise meet the minimum density requirements.
