Similar questions have been asked many times over the years but my answer will always be the same.
I don’t have a “top 2” or a “top 5” or a “top 10” or even a “top 100” list because there is no such thing as the “best mattress” in general terms … there is only a mattress that is “best for you”, regardless of whether the same mattress may be “best” for anyone else. Every person can have different budget ranges, different needs and preferences, and different criteria that are all important parts of their own personal value equation that can be very different from someone else (including me) and any list that I would put together would only be relevant to me.
I do recommend the members of this site “as a group” (currently just over 50 manufacturers or retailers) because I believe they compete well with the best in the industry in terms of their quality, value, service, knowledge, and transparency but I don’t make specific recommendations or suggestions for mattresses, combinations of materials and components, or specific manufacturers because there are too many unknowns and variables involved that are unique to each person and there are also there are also many other sources of good quality/value mattresses across the country or online that aren’t members of this site (at least yet).
While I can certainly help with “how” to choose … again it’s not possible to make specific suggestions or recommendations for either a mattress, manufacturers/retailers, or combinations of materials or components because the first “rule” of mattress shopping is to always remember that you are the only one that can feel what you feel on a mattress and there are too many unknowns, variables, and personal preferences involved that are unique to each person to use a formula or for anyone to be able to predict or make a specific suggestion or recommendation about which mattress or combination of materials and components or which type of mattress would be the best “match” for you in terms of “comfort”, firmness, or PPP (Posture and alignment, Pressure relief, and your own Personal preferences) or how a mattress will “feel” to you or compare to another mattress based on specs (either yours or a mattress), sleeping positions, health conditions, or “theory at a distance” that can possibly be more reliable than your own careful testing (hopefully using the testing guidelines in step 4 of the tutorial) or your own personal sleeping experience (see mattress firmness/comfort levels in post #2 here).
I or some of the more knowledgeable members of the site can help you to narrow down your options, help you focus on better quality/value choices that are available to you either locally or online, help you identify any lower quality materials or weak links in a mattress, act as a fact check, answer many of the specific questions you may have along the way that don’t involve what you will “feel” on a mattress, and help with “how” to choose but only you can decide which specific mattress, manufacturer, or combination of materials is “best for you” regardless of the name of the manufacturer on the label or whether anyone else (including me) would have the same criteria or circumstances or would make the same choice.
I’m not sure what you’ve read since you found the site but 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” 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 you will sleep), durability (how long you 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.
If you are only considering online options then the mattress shopping tutorial includes a link to a list of the members here that sell mattresses online (in the optional online step) and many of them sell latex and latex hybrid mattresses that use different types and blends of latex that have a wide range of different designs, options, features, return and exchange policies, and prices that would be well worth considering.
When you can’t test a mattress in person then the most reliable source of guidance is always a more detailed phone conversation with a knowledgeable and experienced retailer or manufacturer that has your best interests at heart and who can help “talk you through” the specifics of their mattresses and the properties and “feel” of the materials they are using (fast or slow response, resilience, firmness etc) and the options they have available that may be the best “match” for you based on the information you provide them, any local testing you have done or mattresses you have slept on and liked or other mattresses you are considering that they are familiar with, and the “averages” of other customers that are similar to you. They will know more about “matching” their specific mattress designs and firmness levels to different body types, sleeping positions, and preferences (or to other mattresses that they are familiar with) than anyone else.
Once you have narrowed down your options to a list of “your finalists” that are all choices between “good and good” and you have confirmed that none of them have any lower quality materials or “weak links” in their design relative to your BMI range and if at this point there are no clear winners between them (which is usually a good indication that you have done some good research) then you are in the fortunate position that any of them would likely be a suitable choice and post #2 here can help you make a final choice based on your more detailed conversations with each of them, your personal preferences, your confidence about PPP and the suitability of each one, their prices, the options you have after a purchase to fine tune the mattress or exchange or return the mattress (or individual layers in some cases) and any costs involved, any additional extras that are part of each purchase, and on “informed best judgement” based on all the other objective, subjective, and intangible parts of your personal value equation that are most important to you.
