Hi jmattress,
Post #2 here and the links it contains to other posts and threads will give you more information about the somewhat more limited options I’m aware of that are available in Oahu.
I agree with you that while OMI makes some very high quality latex mattresses … they are not in the best value range compared to other similar latex mattresses.
I didn’t realize that Sears there carried the Classic Brands and when I called them in Honolulu they said they didn’t have it on the floor (they are sold online by Wayfair). The only “so called” latex mattress they carried was the Stearns & Foster which I would avoid because they have as much or more polyfoam in the comfort layers than they do latex, the latex is mostly synthetic Dunlop, and they are not good value.
Did one of the stores you visited have the Classic Brands on the floor?
If they did … they can be good value but I would want to know the type and blend of latex they used, the layering of the mattress, and the quality/density of the polyfoam they used. They can be a low cost latex/polyfoam hybrid choice. Their base polyfoam layer is 1.8 lbs and if the latex is Talalay it comes from Latex International.
Hope this helps.
