Hi Lina,
I would make sure that you’ve read the mattress shopping tutorial here.
Yes … you can read more about how they compare in post #4 here.
I’m guessing you mean Astrabeds? If that’s correct then you can see some of my comments about Astrabeds and some of their sister companies in post #2 here and in post #3 here and a forum search on Astrabeds (you can just click this) will bring up more information about them as well. They have recently introduced a new latex lineup that uses organic Dunlop latex (see posts #6 and #7 here)
There is more about the most important parts of the “value” of a mattress purchase in post #13 here that will help you make more meaningful comparisons between mattresses.
The quality of a mattress and how it compares to other mattresses depends on the type and quality of the materials inside it and often has very little to do with the price of the mattress. For example the Astrabeds HarmonyBed includes three 3" layers of 100 % natural organic Dunlop inside a cotton zip cover quilted with wool and is listed for $2199 in queen. It would be most closely comparable to the SleepEZ 10" natural latex mattress with 100% natural Dunlop layers (they also have Talalay latex available as an option as well) which lists for $1750 (less an additional 5% discount for the forum members here) except the Dunlop latex wouldn’t be certified organic. The quality, performance, and durability of 100% natural Dunlop and 100% natural organic Dunlop is the same except for the organic certification itself so you would need to decide whether the additional cost for an organic certification was worth it to you. You can read more about organic Dunlop and the different types and blends of latex in post #6 here.
There is more about the effect of thickness in post #14 here. Whether it’s “worth it” to you or not would depend on whether two layers or three layers was a better match for you in terms of PPP (Posture and alignment, Pressure relief, and Personal preferences).
The best way to decide on the type of latex, how many layers, or the firmness level for each layer that would be best for you would be based on your own personal testing on a specific mattress (or a mattress that was closely comparable). When you can’t test a mattress in person then the best way to decide the type, number, and firmness of the layers that would be best for you would be based on a more detailed conversation with a knowledgeable and experienced online manufacturer who can help “talk you through” the options they have available that would have the best chance of success based on the “averages” of their customers that are similar to you.
