From Danny-
I am looking at a Sealy Posturepedic Natural Beginnings Ultra Plush from Mattress Firm. The number comparisons kind of lead to the Akerman ultra plush, but I am concerned it might be too soft. I get that the difference in the natural is the bamboo covering. I am also wondering about the reference to rayon in the specs of the Natural Beginnings Ultra Plush and to heat issues associated with manufactured fibers.
Helllo Danny,
Everybody is different and some people are more Sensitive to synthetic foams than others. Unfortunately I can not tell you if you are one of these people, you would need to know this yourself.
If you are concerned the Ultra Plush may possibly be too soft for you, then you could purchase the Plush. A mattress will soften up over time, AND if a mattress is not soft enough for you it is easy to manipulate the mattress by adding a topper to it. If the mattress is too soft, there is nothing you can do to make it firmer.
