There are many mattresses to choose from for better back health. Which did you choose?
I chose a memory foam mattress. 
Many studies about using a memory foam mattress offer mixed results based on how they are used by the individual. How did you decide on the one you purchased?
I basically just browsed Amazon and found one I could afford.
Be sure to read the warranty completly. That way if the mattress turns out to be one you do not like you can get your money back.
It has been fine so far. It does seem to be a bit better for my back than my old spring mattress.
The responsiveness of memory foam helps relieve the pressure on our body unlike mattresses with coils.
Yeah, I probably would not go back to a spring mattress.
Innerspring mattresses are the most commonly purchased but also have the lowest satisfaction rating.
Foam does seem like the evolution of the product, but people can be slow to adopt.
