Economical Mattress That’s Soft and Supportive

by Jed Harrington

The Beautyrest BR800 Medium California King Size Mattress is a smart choice if you want to keep your cost at a minimum, but still get a mattress that’s engineered to last the next 10 years. This mattress is among the softest mattresses on our site at this price point, which makes it a fantastic choice if you want a mattress you can really sink into.

Soft, Supportive Comfort

The initial feel of the Beautyrest BR800 Medium is rather soft. Although it feels quite conforming and soft, it is still fully capable of successfully supporting the lower back. Scoring a Comfort Scale score of 7 out of 10 (10 being the softest), this is a wonderful option for the soft mattress lover.

Expertly Engineered Coil System

The Beautyrest 800 Series Plush Pocketed Coil System is the design all other manufacturers attempt to remake, and for good reason. This individually pocketed coil system is capable of conforming to the unique curves of the body better than tied units, all while supplying solid support to the lower back. Its high carbon steel construction is carefully engineered to ensure support that will last over the next 10 years or more.

DualCool Technology Creates Cool Comfort

Recently incorporated into this line, the DualCool Technology layer makes use of a quilt that is designed to help wick away moisture and keep you sleeping thermal neutral. In addition, it’s anti-microbial to ensure you can rest in a healthier environment.

Conveniently Compatible With Power Foundations

Upgrading to a sleep system is simple because this mattress is compatible with all modern adjustable bases and power foundations.

Solution for Cost Conscious Soft Mattress Lovers

The BR800 Medium California King Size Mattress may not include all of the bells and whistles used in higher end models, but at this price point it's still very impressive. The coil system is solid and incorporates a notable update from the previous line of mattresses at this price point. If you are on the lookout for a soft comfort level and want to keep your cost at a minimum, this is a great way to go.
