My Feelings About the Beautyrest Silver Adda 4 Medium Firm

by Jed Harrington

The Beautyrest Silver Adda 4 Medium Firm Queen Size Mattress makes a great choice if you're trying to keep your cost down but still want a great mid-tier mattress with a firm comfort level that's not incredibly hard. This mattress incorporates a solid coil system, thoroughly tested comfort materials, and a great edge support-- everything necessary to get quality sleep without breaking the bank.

Has a Score of 4 on Our Comfort Scale

Getting a Comfort Scale score of 4 out of 10 (10 being the softest), the Adda 4 Medium Firm offers exactly the kind of comfort most people think of when they say they prefer a firm mattress. Its initial padding keeps you from feeling as if you're sleeping on a carpeted floor, and it provides adequate body contouring while delivering solid lower back support.

Solid Support From a Well-Known Coil System

Recognized as one of the best coil systems on the market, the Beautyrest Pocketed Coil System contours to the unique shape of your body while guaranteeing there's plenty of solid lower back support. Built using high carbon steel, this coil system is made to last, and it's completely compatible with all modern adjustable bases. The simple yet effective design minimizes transfer of motion for sound nights of sleep.

Tend to Sleep Warm? Not Anymore.

Dual Cool Technology creates a cooling surface that will keep you sleeping comfortably cool throughout the night.

Edge Support Ensures Consistency in Comfort

You can feel free to sleep close to 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 very helpful feature since it creates up to 10% more usable sleep surface compared with mattresses that don't have an edge support.

Is the Adda 4 Medium Firm a Good Choice for Your Preferences?

There may be better options available from the Silver collection, but for the money, the Beautyrest Silver Adda 4 Medium Firm is able to deliver a level of comfort and support that makes it a fantastic choice in the mid-price mattress category. This mattress is dependably constructed and comes backed by a generous 10-year warranty to ensure your satisfaction.
