How to Choose the Best Mattress

Opt for a mattress with good support. The best mattress should keep the spine in the same shape as if the body were in a standing position with all points of the body supported. Try out the mattress in the store to make sure the mattress supports the shoulders, hips and lower back. Follow the Goldilocks' rules of finding the "just right" support -- not too soft or too firm. Look for a pillow top, which can make a firm mattress feel plush.

Choose the right size mattress. The average person turns 40 to 60 times during the night according to the Better Sleep Council. They recommend that two people sharing a bed look at a 60-inch queen-sized mattress or a 76-inch king mattress.

Consider alternatives to a traditional coil mattress. If you don't move around much at night or suffer joint sensitivity, a foam mattress, which conforms to your body shape, may be the best choice for you according to WebMd. If an adjustable air mattress solves sleep preference issues in your household, look for a mattress with small chambers because it will offer the most support.

Buy a new mattress for value and durability. Inner-spring coils still offer the most support and durability. If inner spring is your choice, look for 680 coils in a mattress for average sized people. Look for 400 coils if you are larger because the coils will be stronger, according to WebMd.
