Hi Nick S.,
It would depend what you mean by “comparable” but they are certainly in the same general category. Every category of mattresses (including latex/innerspring hybrids) can include hundreds or sometimes thousands of different mattresses with different designs, different “feels”, different characteristics, and different firmness levels. Every layer and component in a mattress (including the cover and any quilting material) will affect the feel and response of every other layer both above and below it so each category will generally include some mattresses that will be a good “match” for you in terms of “comfort”, firmness, and PPP (Posture and alignment, Pressure relief, and your own personal preferences) and others that use the same type of materials and are in the same category but have a different design that be unsuitable for you to sleep on even if the actual materials and components are the same type.
While I do recommend the members here “as a group” because I believe that they compete well with the best in the industry in terms of their quality, value, service, knowledge, and transparency … there are also many other sources of good quality/value mattresses as well that aren’t members of this site (at least yet).
I don’t 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” or PPP or how a mattress will “feel” to you or compare to another mattress based on specs (either yours or a mattress) or “theory at a distance” that can possibly be more accurate 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).
While nobody can speak to how any specific mattress will “feel” for someone else because again this is too subjective and relative to different body types, sleeping positions, and individual preferences, sensitivities, and circumstances and you are the only one that can feel what you feel on a mattress … outside of PPP (which is the most important part of “value”), the next most important part of the value of a mattress purchase is durability which is all about how long you will sleep well on a mattress.
This is the part of your research that you can’t see or “feel” and assessing the durability and useful life of a mattress depends on knowing the specifics of its construction and the type and quality of the materials inside it regardless of the name of the manufacturer on the label (or how a mattress feels in a showroom or when it is relatively new) so I would always make sure that you find out information listed here so you can compare the materials and components to the quality/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.
Since both of the mattresses you are considering use very similar materials and components … they would certainly be comparable in terms of durability even though they may not be comparable in terms of “comfort”, firmness, and PPP.
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 and their guidance will give you the best chance of success.
Once you have narrowed down your options to a list of finalists that are all choices between “good and good” (which you have) and none of them have any lower quality materials or “weak links” in their design (which they don’t) 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 own local testing and/or your more detailed phone conversations about each of them, the firmness and suitability of each one, their prices, your preferences for different types of materials and components, designs, or types and blends of latex, the options you have after a purchase to fine tune the mattress or exchange or return the mattress or individual layers 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.
