Simmons BeautySleep® Murray River Plush Top Mattress Set 440-631.
Concerning mattresses, "comfort" refers to the way the surface of the mattress feels beneath your body. Mattress companies most commonly describe comfort in the following terms: Pillow Top, Eurotop, Plush, and Firm.
The amount of space you have is usually the most important factor when purchasing a mattress. It's recommended to have the largest bed your space will allow. Your bed should be wide enough and long enough so that each sleeper can rest comfortably in their space. Try to purchase a bed that is at least four inches longer than the height of the tallest sleeper.
ROTATING YOUR MATTRESS:
It is recommended that you rotate your mattress occasionally, which will increase its comfort life and longevity. However, the option to rotate your mattress is not required for your warranty to remain valid.
