Hi SeaLifeLover,
You can see the details of their previous return policy on the wayback machine here and their return/exchange policy used to be conditional on being inside their delivery service area (inside a 100 mile radius of NYC) and on having tried their mattress in a showroom before a purchase. According to their site they currently only have a 90 day exchange policy (not a return/refund policy) but they don’t list the specifics on their site.
There really isn’t much additional information that I can share outside of what I’ve already linked unless you have a specific question I can answer but based on your comments you seem to have a good understanding of the pros and cons and tradeoffs involved in the choices you are considering so it’s really a matter of deciding which of the tradeoffs involved are most important to you.
Once you are down to a list of finalists and you are confident that they would all be a good match for you in terms of PPP (or you have good options after a purchase if you aren’t) and that there are no lower quality materials or weak links in any of them in terms of durability then you would be down to finalists that are comparing “good to good”. If there are no clear winners between them at this point (which is usually a good indication that you have done some very good research) then you are in the fortunate position that any of them would likely make a good quality/value 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, 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. Sometimes a final choice may even come down to very minor differences or can sometimes just be a matter of “gut feel” or “educated best judgement”.
