Seeking advice on offset coil + latex mattress

Hi VAn23,

In most cases the weak link of a mattress isn’t the innerspring but the foam on top of them that can soften and break down prematurely. This is why it’s so important to make sure that you deal with transparent manufacturers and retailers that will provide you with the specific layers and components inside any mattress you are considering (especially in the comfort layers). Offset coils are certainly a suitable support component and the number of coils in your mattress is fine as long as you are OK with the greater motion transfer that is typical of innersprings with helicals. A 3 zone innerspring means that the coils in the center of the mattress are firmer to provide better support under the heavier pelvis and lower back area. This can be helpful to provide better alignment. There is more about innersprings in this article and in post #10 here.

Outside of careful and objective testing for PPP … the next most important part of a mattress purchase is to make sure you know materials and components inside the mattress (see this article) so you can make sure there are no potential weak links in the mattress (see post #4 here) and so you can make more meaningful comparisons with other mattresses based on the parts of your personal value equation that are most important to you.

If you can provide the specifics of all the layers and components in the Irvington and post them on the forum I’d be happy to make some comments about the mattress. The innerspring, The Talalay latex, and the cotton felt are all good quality materials and components but the description you linked doesn’t include the thickness and density of the High Density Support foam or the order of the layers. The mattresses at Northwest Sleep are made by Parklane which is one of the members of this site which means that I think highly of them and in general they would make good quality/value choices.

You can read some of my thoughts about Essentia and their claims and some forum discussions with them in this thread and this thread and posts #3 and #4 here.
