An all foam mattress, and memory foam in particular, will only make his back problems worse.
He's being taken in by the hype surrounding that kind of mattress...and none of it is true, beyond a year or two.
A mattress with a pre-compressed, individually pocketed coil, will provide contouring "UPWARD" support for his herniated discs.
(A foam mattress provides no upward support).
The best of what we carry, is the Natura of Canada Greenspring.
These mattresses provide the highest coil count....strong coils that are double tempered...and upholstered with natural latex.
Latex is and has been thee best upholstery material for the last 100 years.
During it's 20 year history, memory foam has proven to be the worst...a toxic chemical soup that is specifically designed to need frequent replacement.
My wife and I have one of these at home. I have lots of disc problems and live without pain...thanks to the mattress.
Of their 4 models, the Ultra Plush is the most comfortable.
