Hi rossco17,
The better options or possibilities I’m aware of in and around the Portland, ME area (subject to making sure that any mattress you are considering meets the quality/value guidelines here) are listed in post #2 here.
Portland Mattress Makers is certainly one of the local options that I would consider yes.
I don’t make specific suggestions or recommendations for either a mattress, manufacturers/retailers, or combinations of materials or components the first “rule” of mattress shopping is to always remember that you are the only one that can feel what you feel on a mattress and there are too many unknowns, variables, and personal preferences involved that are unique to each person to use a formula or for anyone to be able to predict or make a specific suggestion or recommendation about which mattress or combination of materials and components or which type of mattress would be the best “match” for you in terms of “comfort” or PPP or how a mattress will “feel” to you or compare to another mattress based on specs (either yours or a mattress) or “theory at a distance” that can possibly be more accurate than your own careful testing (hopefully using the testing guidelines in step 4 of the tutorial) or your own personal sleeping experience (see mattress firmness/comfort levels in post #2 here).
I would also keep in mind that assuming that the materials in a mattress you are considering are durable enough for your body type and meet the guidelines here … the choice between different types and combinations of materials and components or different types of mattresses (see this article) are more of a preference and a budget choice than a “better/worse” choice.
I or some of the more knowledgeable members of the site can certainly help you to narrow down your options, help you focus on better quality/value choices that are available to you either locally or online, help you identify any lower quality materials or weak links in a mattress you may be considering, act as a fact check, answer many of the specific questions you may have along the way that don’t involve what you will “feel” on a mattress, and help with “how” to choose but only you can decide which specific mattress, manufacturer, or combination of materials is “best for you” regardless of whether anyone else has the same criteria or would make the same choice.
