Hi DakotaMagnum,
Almost all of the mattresses you are considering use good quality materials however there are a few of them that I would want more information about the materials inside them to make sure there were no weak links and to be able to make more meaningful comparisons.
[b]RoomandBoard (Restwell?) –
Encased coil ultra-plush[/b]
I would want to know the density of the polyfoam layers in this mattress. I believe they use 1.2 lb polyfoam (which I would want to confirm) which could be a weak link in this mattress.
[b]Original Mattress Factory
Ortho Eurotop
Ortho Premier super pillow top[/b]
I would want to know the specifics of the layers and foam densities in these mattresses as well. While I believe they are inside the guidelines I would use (1.5 lb polyfoam in a two sided mattress) … I would want to know the specifics to make more meaningful comparisons. Even though a two sided mattress is more durable than an equivalent one sided mattress (see post #3 here) … if the 1.5 lb polyfoam layers on each side are fairly thick and they are on the bottom end of the quality/density guidelines I would use, then you would likely have some body impressions over time although they would be much less than a one sided mattress and would also be less likely to have a significant effect on PPP.
I would definitely want to know the specifics of the materials in this mattress because there could be some weak links and in spite of the price (or the “showroom feel” or “looks”) some of the materials may be lower quality and less durable than some of the other mattresses you are considering.
Other than these … none of the mattresses you are considering have any weak links or cautions and I would remove durability as a factor and put most of your emphasis on which one was the best match for you in terms of PPP and the other parts of your personal value equation that are most important to you.
This would be a preference based on how it feels to you. Channel quilting can have a little bit plusher feel as the wool isn’t compressed as much and is lofted more than “regular quilting” although some people may not like that the sleeping surface is less even or on occasion will mention that they can “feel” the bumps and valleys. I would make this a preference choice.
[quote]As far as the beds at Rest Assured and the difference between micro coil and 3" latex:
Do you feel one would hold up better over time vs the other?[/quote]
Microcoils are a very durable component and I would choose between them based on PPP … not based on durability.
Only if it’s a better “match” for you in terms of PPP.
Not with a better manufacturer such as Rest Assured but it would also depend on the tradeoffs involved (the savings, how it compares to the Blue Moon in terms of PPP, whether it comes with a warranty, and whether you would lose any of the other benefits that comes with a new mattress such as their 6 month firmness guarantee).
This would probably be a good idea since they are so close and I believe they are also transparent about the type and quality of the materials they use in their mattresses so you could make some meaningful comparisons.
Your online options with Arizona Premium are also of course high quality/value options and once you have talked with Arizona Premium in more detail then the one that you believe you would prefer out of the two would also be well worth including as one of your finalists.
With the exception of the comments I made at the beginning of this post (if any of these mattresses are still in the running) you are down to final choices between good and good and since there are no “bad choices” in the group and if there isn’t a clear winner then which one is “best for you” would depend on all the objective, subjective, and intangible parts of your personal value equation that are most important to you.
You’ve done some great research and you have some very good options to choose from
