Hi MNBuyer,
Given that Serta is rather coy about their mattress specs, I'm wondering how to go about shopping for comparable mattresses.
I wouldn't suggest using any mattress (especially a major brand mattress) as a reference point. The goal of any mattress purchase is to compare every mattress you are testing against a common set of criteria in terms of PPP (Posture and alignment, Pressure relief, and Personal preferences), the quality of the materials, and the parts of your
personal value equation
that are most important to you rather than using another mattress as the "target". You would be limiting your options far too much by looking for a "comparable" to another mattress if what you are using as a reference point isn't a great choice in the first place.
The layers of the iComfort Directions Reinvention are described in their literature & website as follows:
Thermo°Cool™ yarn fabric cover with TENCEL® fibers
EverCool® Gfx Memory Foam + Serta® PillowSoft™ Foam
Cool Reaction® Slow Recovery Latex Foam
Cool Action™ Dual Effects® Gel Memory Foam
Pods™ Gel-Activated Support
Comfort Last® Foam Core with Ultimate Edge® Support
Unfortunately ... this description doesn't include the information you would need to assess a mattress, identify any weak links in its construction, or make any meaningful comparisons to other mattresses in terms of quality or value. The information you would need about any mattress you are considering is in
this article
and I would pass any mattress by where this information wasn't available to you.
Your highest chance of choosing a mattress that is "best for you" is to follow the steps in the
tutorial post
one by one and I wouldn't get distracted by mattresses where you know ahead of time that the information you need to make an informed choice isn't likely to be available. There are too many good options available that can "match" all your criteria as well or better to spend a lot of time looking at the worst ones.
