Best in terms of body support.

- Randall K., Portland, OR

After three months of sleeping on this Beautyrest, my aching back is practically a thing of the past. The latex and memory foam combo really is the best in terms of body support.  My wife also loves that the bed has reduced motion disturbance because I get up early (4AM) for work. Now she can sleep late and doesn’t have to suffer.

In a class all its own.

- Noah D., Canby, OR

I chose this model because it was plush, yet still felt deeply supportive. After five weeks I am getting the best sleep I’ve had in years and feel like a new man. We splurged on the California King with an adjustable power base and couldn’t be more thrilled. Plus, Mattress World gave us a great price that still fell within our budget. Be warned, this isn’t your typical memory foam mattress, it’s in a class all its own.
