Hi Your Loyal Vizier,
Welcome to the Mattress Forum! 
You may have already seen my comments about the Consumer Reports mattress ratings and recommendations in post #2 here and in this topic. While they may be a good source of information about more “objective” purchases, I would consider them to be an unreliable source of information or guidance about purchasing a mattress and their “ratings” are somewhat nonsensical and meaningless. My thoughts are also shared by most of the more knowledgeable people in the industry (see post #5 here for an example).
You can see my comments about the Sleepopolis Site (and many other similar so called “review sites” which are really just revenue sites that know little about mattresses or mattress materials) in post #11 here and in posts #4 and #6 here but the good news is that you ended up buying a great quality/value mattress in spite of the somewhat questionable information there.
The “bed in a box” category is one that continues to grow, so if a product being able to be shipped either compressed or in components is important to you, you certainly have many choices.
Just in case you haven’t read it yet … the first place to start your research is the mattress shopping tutorial here which includes all the basic information, steps, and guidelines that can help you make the best possible choice … and perhaps more importantly know how and why to avoid the worst ones.
Two of the most important links in the tutorial that I would especially make sure you’ve read are post #2 here which has more about the different ways to choose a suitable mattress (either locally or online) that is the best “match” for you in terms of “comfort”, firmness, and PPP that can help you assess and minimize the risks of making a choice that doesn’t turn out as well as you hoped for and post #13 here which has more about the most important parts of the “value” of a mattress purchase which can help you make more meaningful quality/value comparisons between mattresses in terms of suitability (how well he will sleep), durability (how long he will sleep well), and the overall value of a mattress compared to your other finalists based on all the parts of your personal value equation that are most important to you (including the price of course and the options you have available after a purchase if your choice doesn’t turn out as well as you hoped for).
Then I would make sure that you find out information listed here about any mattress you’re considering so you can compare the quality of the materials and components to the durability guidelines here to make sure there are no lower quality materials or weak links in a mattress that would be a cause for concern relative to the durability and useful life of a mattress before making any purchase.
Once you’ve done that bit of reading, you might then wish to look online and use the experience and expertise of the members listed in post #21 here who are all very experienced and knowledgeable and specialize in providing the type of help and guidance on the phone that can help you make good choices with the type of mattress you are considering. There are a wide range of latex and memory foam and option (shipping compressed or in pieces) included in the choices there and I believe that all of them compete well with the best in the industry in terms of their quality, value, service, and transparency.
Their detailed knowledge of their mattresses and how they fit with different body types and sleeping positions along with your feedback from local testing, a customer base of many people that they can use as reference points, and any exchange, return, or any options they have available to customize a mattress after a purchase can help lower the risk of an online purchase.
You may also want to visit the Simplified Choice thread here, as it provides quite a few details about many of the “one-size-fits-all” mattresses, most of which ship compressed to your home.
If you come up with other more specific questions, let me know.
I appreciate your kind words.
