Hi Ferenein,
There is more about the most important parts of the “value” of a mattress purchase in post #13 here that can help you make more meaningful comparisons between mattresses.
The most important part of “value” is that a mattress is a good match for you in terms of PPP (Posture and alignment, Pressure relief, and Personal preferences) so there is certainly some “value” in being able to test a mattress in person (hopefully using the testing guidelines in the tutorial post) to make sure that it’s a good “match” for you.
The Midori uses organic Dunlop latex and a cotton cover quilted with wool so there are no weak links in the mattress in terms of durability.
There are certainly other mattresses that are available to you that are made by some of the online members here that are listed in the tutorial (there is a link to them in the optional online step) and there may be others that are similar that are available locally to you as well depending on where you live. If you let me know your city or zip code I’d be happy to let you know about any of the better options or possibilities I’m aware of in your area.
If another mattress uses either uses two 3" layers or a single 6" layer of 100% natural Dunlop latex (or organic Dunlop) and also has a similar cotton cover quilted with wool and uses the same type of latex with the same firmness level as the Midori and has a cover that has the same type of cotton fabric and amount of wool and quilting pattern then the mattress as a whole would also be very similar as well. There is also more about the different types and blends of latex and more about organic Dunlop latex in post #6 here and the posts it links to because the Eco Bliss uses Talalay and the Midori uses Dunlop and there are many people that prefer one over the other. There is also more about the differences between Talalay and Dunlop in post #7 here.
Some of the other options that you have available would be in a lower budget range so from a “commodity” point of view they would be better value but of course the value of a mattress purchase involves much more than just the cost of the raw materials vs the price of the mattress. Most of them also have a better exchange and return policy which can help reduce the risk of an online purchase that you can’t test in person before a purchase. Once you are down to final choices that are between “good and good” (see post #2 here) then which one would be the best value for you (regardless of whether it may be the best value for someone else with different criteria) would depend on all the objective, subjective, and intangible parts of your personal value equation that are most important to you.
