What I Think About the Beautyrest Silver Adda 4 Medium Firm

by Jed Harrington

The Beautyrest Silver Adda 4 Medium Firm Full Size Mattress makes an amazing choice if you're looking to keep your cost at a minimum but still get a great mid-tier mattress with a firm comfort level that's not incredibly hard. This mattress features a solid coil system, independently tested comfort materials, and a great edge support-- everything needed to get quality sleep without breaking the bank.

Comfort Scale Rating of 4

With a Comfort Scale score of 4 out of 10 (10 being the softest), the Adda 4 Medium Firm is exactly what most people imagine when they say they like a firm mattress. Its initial padding prevents you from feeling as if you're sleeping on a carpeted floor, and it offers adequate body contouring while ensuring solid lower back support.

Super Support From a Popular System

One of the best coil systems in the bedding industry, the Beautyrest Pocketed Coil System contours to the unique shape of your body while guaranteeing there's plenty of solid lower back support. Made from high carbon steel, this coil system is built to last, and it's fully compatible with all modern adjustable bases. Its simple but effective design helps minimize motion transfer for sound nights of sleep.

Sleep Warm? This Mattress Can Help.

Dual Cool Technology creates a cooling surface designed to help you sleep comfortably cool throughout the night.

Edge Support Ensures Consistency

It's okay to sleep near the edges without feeling like you're going to roll off the side or feel forced back toward the center. The foam-encased edge support is a highly beneficial feature since it adds up to 10% more usable sleep surface compared with mattresses that have no edge support.

Is the Adda 4 Medium Firm Right for Your Particular Needs?

Are there better options available in the Silver collection? Yes. But for the money, the Beautyrest Silver Adda 4 Medium Firm is able to offer a level of comfort and support that makes it a noteworthy choice in the mid-price mattress category. This mattress is well-made and comes backed by a generous 10-year warranty.
