Hi merujo,
It’s sad that so many salespeople are so misinformed. They may be nice mattresses and even have better than average value but the Hybrid 3.0 line certainly isn’t 100% latex (as you know).
A mattress is only as good as the materials inside it and while the Comfort Solutions Extended Life mattresses do use some higher density foam (2 lbs +) in the layering … it’s still important to know ALL the layers so you can identify any potential weak links in a mattress you are considering … especially when you are in a heavier weight range. this is the job of the retailer to provide this to you and if they can’t or won’t then I would pass them by. There are too many good choices that will for you to spend much time tracking down the specs that are necessary for you to make any meaningful assessment of the quality and value of a mattress.
While the Washington, DC area is not the most “mattress friendly” area in the country (many other areas have a larger number of better choices, manufacturers or options available) … the better ones I know of are listed in post #2 here.
You’ve probably read this already but just in case … post #1 here and the information it links to is the most important post on the forum and will give you the basic information you need and a step by step guideline that can help you make much better choices.
When you are in higher weight ranges … what is “soft” and “firm” to you will not be the same as others who are lighter and the importance of more durable materials (higher density polyfoam and memory foam, good quality latex, lower gauge thicker springs etc) can’t be stressed enough and finding and working with people who are knowledgeable about mattresses and materials and will take the time to educate you more than “sell” you and tell you the “why” behind the “what” is particularly important.
