My Thoughts Regarding the Beautyrest Silver Adda 4 Medium Firm

by Jed Harrington

The Beautyrest Silver Adda 4 Medium Firm King Size Mattress makes an excellent 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 really hard. This mattress incorporates a solid coil system, thoroughly tested comfort materials, and a great edge support-- all the things you need to get quality sleep without breaking the bank.

4 Out of 10 On Our Comfort Scale

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

Solid Support From an Established Coil System

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

Sleeping Too Warm? Not Anymore.

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

Edge Support Keeps Comfort Even

You can fall asleep 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 fantastic feature since it creates up to 10% more usable sleep surface compared with mattresses that don't include an edge support.

Is the Adda 4 Medium Firm a Good Choice for Me?

Although there are better options available from the Silver collection, for a lower price point the Beautyrest Silver Adda 4 Medium Firm is able to deliver a level of comfort and support that makes it an amazing choice in the mid-price mattress category. This mattress is dependably constructed and comes backed by a generous 10-year warranty to ensure you're fully satisfied with your purchase.

Mattresses change names from store to store, to prevent you from comparison shopping. We think this is wrong, and have done the work to help you understand what models on our site match up to those you may have tried in a store. That way, you can always get the best price.
