Hi kayla,
They should be fine with an adjustable … even if they are covered. The worst case is that you may need to do some adjusting if they do shift but this shouldn’t be an issue. Having said that … I believe that OMI (Organicpedic) will only warranty their mattresses if they are purchased with their own foundation (see here) and I don’t believe that floor models are covered by their warranty either (see the attachment) so even if it would “work” on an adjustable you would void your warranty which wouldn’t be a good idea.

where here?in The US lots of alternatives, here ,not so much.[/quote]
I provided a list of alternatives that ship across Canada in my reply here.
If you let me know your city or postal code I can also let you know about any of the options or possibilities I’m aware of that may be reasonably close to you as well (I’ve asked you this before but I don’t see your reply).
You won’t find one “exactly” the same (there is more about the different ways that one mattress can “match” or approximate another one in post #9 here) but there are many others that would use the same type of latex that would be “similar” and may be just as good a “match” for you in terms of PPP that are in much lower budget ranges and have better exchange/return options.
Some of the online options available to you do allow for returns so you can use your own actual sleeping experience to “test” the mattress for the entire length of the trial period (instead of just 20 minutes in a store) with little risk.
If you have a component mattress where you can rearrange or exchange individual layers then you could make it firmer in either the comfort or support layers but with a “finished” mattress its really not possible to “firm up” a mattress outside of adding a firmer topper which would give you a firmer feeling sleeping surface but wouldn’t “firm up” the support layers underneath you and in some cases may make any alignment issues worse.
This certainly isn’t an option I would consider … especially if you are in higher weight ranges … since you will likely be back to having the same or even worse issues than you do now fairly quickly.
