Hi rhemy1,
It is difficult to make any suggestions with certainty, as again a mattresses comfort and ability to provide support while you sleep is unique to you having a unique body type and needs and preferences. Thanks for providing additional stats; I will say that at a higher BMI, while you’ll need to put a special emphasis on more durable materials and constructions and probably on mattresses that are thicker have firmer comfort and support layers (firmer materials feel softer for heavier people and firmer support layers are usually important to for good alignment for higher weights). I would especially make sure you read[url= https://forum.mattressunderground.com/t/ultimate-dream-mattress-firmness-level/#18643] Post #2 here [/url]that has some generic guidelines for different body types and sleeping positions and[url= https://forum.mattressunderground.com/t/memory-foam-toppers-do-any-good-ones-exist/#9345] post #14 here[/url] has more about the benefits of thicker comfort layers and thicker mattresses. You will likely want to look at firmer-feeling mattresses to provide enough support and prevent any misalignment in your spine or joint pain, but not that firm that it created pressure points since you are a side sleeper. This is to say that I would definitely run all of this summarized info by the retailer/manufacturer themselves as they are the best to know how their mattresses and designs work with different body types, weights, and sleeping positions. Which is why it is so important to speak with someone knowledgeable rather than be given a “script response” from a sales rep that has little to no experience with how the mattress works.
Since it sounds like you are leaning towards an all latex mattress, some options from TMU trusted members list would include a DIY mattress construction under the direct supervision of a trusted member such as DIY Mattress, who allow you to create your own customized mattress, they have 2" and 3" layers of both Dunlop(this a denser, firmer latex with a ‘bouncy’ feel) and Talalay (A softer more responsive feel in case you like that better) of various firmness levels, allowing you to use for example, a Talalay layer at the top for comfort, with Dunlop below to provide support. By providing them your stats and sleeping preferences they can create a layered latex mattress which you can place on a base like a platform or adjustable bed frame.
Member Latex Mattress Factory specializes in mattresses for plus sized people and are extremely skilled in guiding consumers to good fit mattress on the DIY construction model, I would go for something with 10" of more of firmer natural latex mattress. (On the call I would make sure to mention the base model construction that you tested in the shop and liked) so that they get a better sense I’d start with these two and then see what other similar options you can find from other members that best fit your personal criteria (price, returns, warranties, and all else that is important to you) such asFlexus Comfort and CozyPure, who likewise offer all-latex mattresses. I have included a list below of all the trusted members who offer all-latex mattresses:
It’s good to see that you started by eliminating the worst contenders then deciding the basics – the feel and firmness you want in a mattress, what materials or options you do or don’t want (like ‘no coils’) You are on the good track. Let us know how far you go and we’ll be happy to make additional comments on any of the mattresses you are considering.
