Hi a35patel,
That’s probably a good decision … especially if you are dealing with a retailer who doesn’t know or understand the importance of knowing what is in the mattresses they are selling.
In most areas of the country what you would need to do is call the local retailers and ask them if they have a polyfoam/latex hybrid with about 3" of latex over the polyfoam. Many retailers are not used to these types of questions (that involve the layers in their mattresses) but the better ones that are more knowledgeable will know right away if they carry this type of mattress. Many manufacturers make something fairly similar. The Ultimate dreams has an option to choose the firmness of the latex you use and the local retailers may not know the ILD (firmness) of the latex in their mattress but at least you would be able to get a sense of the general “feel” of this type of mattress even if you may not be able to find out enough details to use them as a more accurate guideline because of differences in design, construction and firmness levels between the ones you test and the Ultimate Dreams.
In your case however you are quite fortunate because you appear to live in Scottsdale and you have some of the best choices in the country available to you because 3 of the members here (including Brooklyn Bedding) are in the general area. They are listed in post #4 here and all of them have some great quality/value mattresses that would be well worth looking at. Brooklyn Bedding generally sells the mattresses they list on their site online only but if you call them to make an appointment they may be able to meet you at the factory to test their beds.
I wish everyone had the kind of local quality and value available to them that you do and you don’t even have to “guess” with an online purchase.
