Hi datwundude.
Welcome to our Mattress Forum!
I am glad you have found us.
It seems that you are on the right track in your search for a new mattress. BMI is a good general place to start and you are looking for the right specs for your weight range to ensure durability. You may have already come across this post in your research but just in case you haven’t read it yet, Post #3 here has more information and suggestions about heavier weights and it is worth reading. Higher BMI people in general will need firmer and thicker comfort layers and firmer support layers than those who are lighter and because no materials will last as long with much higher weights the quality and durability of the materials and components is even more important than normal.
I think you might be misreading some of the information provided by Arizona Premium. They do not carry a “Serenity Mattress”; they do however make some comparisons between mattresses where they indeed mention this bed here and here. Serenity is a Savvy Rest mattress which uses good quality materials but has a higher price point so people considering them would want to make some personal value equations. Arizona Premium offers comparable mattresses at a much lower price point and if you let me know the mattress you are considering I’d be happy to comment upon it. They are also one of the members here which means that I think very highly of them and that I believe they compete well with the best in the industry in terms of their quality, value, knowledge, service, and transparency.
The KISS mattress is produced by SleepEZ, one of the oldest and most-respected independent mattress manufactures in the United States. SleepEZ is very experienced in both latex and memory foam mattresses, and I do think highly of them, their products and their experience.
Thank you for mentioning this… it triggered me to update the information on the Simplified Choice thread for this Mattress!
Addable is in the process of making some product and website changes and the mattress matching questionnaire has been removed from their website. There is caution on this mattress for higher weight ranges as it has 2" of 4lb Memory foam and 2" of 1.8 lb polyfoam which is less than what is usually recommended.
It is not possible to estimate the impact of lower quality components, except in general terms, as this depends on many interconnected factors and a combination of the mattress design, foams used, foam formulations, thickness and the positioning of a specific layer within the mattress along with the mechanical stress and compression that each sleeper exerts on the mattress. All foams go through stresses, and the higher the mass placed upon those foams, especially the uppermost layers, the higher the mechanical stress. A mattress that has softened or changed to the degree that it no longer provides the support, pressure relief, or personal preferences for one person may still be fine for someone else. It’s usually not the final breakdown of materials that leads to the need to replace a mattress but the gradual loss of comfort and support that finally “crosses” a line and at some point is no longer suitable for that person to sleep on. Each person’s “line” can be very different. There is more about the varied factors involved in mattress durability in post #2 here .
Kiss mattress has 2 firmness choices to cover a broader range of the bell curve that will fit more people than a single firmness choice. Pure Green has a basic 7" model and 9" that is customizable before and after purchase (the heavy duty Zipper encasement is hidden under the bottom edge of the mattress.) And they are both suitable for higher weight ranges.
If you let me know which of the 10" and 13" mattresses you are looking at and provide the information I’d be happy to make some comments. Be sure that you find out information listed here so you can compare the quality of the materials and components to the durability guidelines here to make sure there are no lower quality materials or weak links in a mattress that would be a cause for concern relative to the durability and useful life of a mattress before making any purchase.
Good luck! and once you’ve had the chance to narrow things down a little further, feel free to post back with any specific questions and I or any of our Expert Members will be happy to assist you.
