Hi Stevio,
I think you are probably wise to hold up just a bit because you will probably end up with a much better mattress at a better price.
Your wife is much lighter so will probably need a mattress that has softer foam in the comfort layers than you will. She may also need and or prefer a slightly softer support layer as well. The lighter a person is … the firmer a specific foam will feel compared to a heavier person. The “curviness” of a person, the overall body shape and weight distribution, and the relative width of the hips and shoulders can also make a difference in the best choices in terms of the thickness and softness of a comfort layer.
This may mean that some couples that are very different in their weight distribution and body shape will often do well with a “side to side” split construction which allows each side of a mattress to be custom layered to each person’s needs and preferences within the same overall thickness. Another alternative is the use of materials that can adjust to a wider range of different weights and sleeping positions (such as latex in either the comfort layers of the layers immediately below this).
It would probably help to know which of the iComfort models you both preferred as they are very different in terms of their layering and feel.
There are also many mattress manufacturers and better outlets in the NJ, NY and the surrounding area and when I do a search for someone I also usually take a look at any local retail outlets that may be worthwhile including in your research so it would help me a lot and save me in some cases several hours if you could let me know your zip code or the closest town or city to where you are so I can limit what I include to 50 miles or so from a certain zip code or city.
Thanks for your post … and as soon as I know where to begin looking from I will let you know any better outlets that I am aware of or discover in my ongoing research.
In the meantime there are a few threads which may be of interest and list some New Jersey manufacturers and outlets. They include Post #4 here (centered on Trenton, NJ.), and Post #2 here, and Post #2 here (centered on Butler, NJ.).
Hope this helps.
