The Carbon Plush is a good way to go if you want something that'll reduce the amount of motion you feel when a partner, child, or pet shifts around or gets in/out of bed. It's coil system and comfort materials are designed to provide undisturbed sleep.

You can expect over a decade of comfort and support from a mattress with a 10 year non-prorated warranty.

If you like a mattress that's not too soft, not too firm, and want something that stands out for technology, comfort, and sustainability, the Carbon Plush is a good choice. Beautyrest has really upped their game on this mattress when you compare it to the previous generation of Beautyrest models priced similarly.
