So, as life would have it, I have been shopping and doing research on a new bed. There is a lot of BS in this market with air beds, water beds, memory foam beds and spring beds with all combinations. Some cost as much as my car!
I have also discovered Latex foam beds that are not not common here in the US, yet are highly rated it seems and reported to be more common in the euro region. They are not cheap, possibly twice the cost of some memory foam units.
They are made modular and in your own preferred layers of density.
As an added plus, the spouse side can also be adjusted for preference by changing layers.
Most of these are sold on line here, with exception of a few stores that carry standard versions such as IKEA.
Durability is also high it seems, with many offering 20 yr warranty.
Experience, comments welcome. Thanks in advance.
