Hi uptick911,
I’m glad you were able to experience the knowledge and service at My Green Mattress and why so many people (including me) think so highly of them.
It sounds like you made a great choice and most importantly … congratulations on your new mattress.
Latex is the most durable of all the foam materials and has been the “gold standard” for durability for many decades. You can see a video in this article of a latex mattress that was used for almost 50 years and while it wouldn’t be realistic to expect that a softer latex mattress will last that long … latex will stay closer to its original properties for a longer period of time than any of the other type of foam. There is more about the factors that can affect durability in post #4 here and the posts it links to but durability is certainly something I wouldn’t be concerned about for many years with a good quality latex mattress such as yours.
