Hi stuuke,
Both of them are members of this site which means that I think highly of them and that I believe that they both compete well with the best in the industry in terms of their quality, value, service, knowledge, and transparency. I certainly wouldn’t hesitate to purchase a mattress from either of them.
There is more information about the 3 most important parts of the “value” of a mattress purchase in post #13 here 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 suitability, durability, and all the other 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).
Since all of the mattresses you are considering are all latex mattresses they would all be very durable choices and none of them have any lower quality materials or weak links that would compromise the durability or useful life of the mattress.
I would also make sure that you have a more detailed conversation on the phone with each of them.
Once you have narrowed down your options to a list of finalists that are all choices between “good and good” (which they are) and you have confirmed that none of them have any lower quality materials or “weak links” in their design relative to your weight range (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 local testing or mattresses you have slept well on, your more detailed conversations with each of them, your confidence about PPP and the suitability of each one, their prices, your preferences for different types of materials (or different 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, 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.
You are certainly looking at some great quality/value choices and I’m looking forward to finding out what you end up deciding
