Hi goldilocks12,
I don’t have any personal experience with the adjustable bed or remote you mentioned so hopefully some of the forum members that have used it will see your post and share their comments about it. “In theory” the neck articulation would probably help if you are sitting up in bed reading but of course different people would also have different opinions about how useful it is for their own specific circumstances. There are also several other adjustable beds that have a similar neck articulation as well.
There is more about the durability and useful life of a mattress and what I would consider to be a reasonable expectation in the quality/durability guidelines here and there are also more detailed comments about the many variables that can affect the durability and useful life of a mattress in post #4 here as well. Since latex is such a durable material the odds are much higher that you would have more “bonus time” beyond 10 years than you would with mattresses that use lower quality and less durable materials.
One of the advantages of a component mattress is that if the softer top layers in a mattress soften or break down before the deeper layers (which is most likely) or if your needs and preferences change over time then you can just replace individual layers instead of replacing the entire mattress.
Yes … even though they have different designs … they would be closely comparable in terms of quality and durability since they both use the same materials (100% natural Dunlop latex).
