What I Think of the Beautyrest Silver Adda 4 Medium Firm

by Jed Harrington

The Beautyrest Silver Adda 4 Medium Firm Twin XL Size Mattress is an outstanding 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 certified comfort materials, and a great edge support-- everything you need to get quality sleep without breaking the bank.

Comfort Scale Score of 4

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

Great Support From a Famous System

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

Sleep Warm? This Will Help.

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

Consistent Comfort

It's okay to sleep anywhere on the surface 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 really 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 Needs?

Are there better options from 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 great choice in the mid-price mattress category. This mattress is well-made and comes backed with a 10-year warranty.

Comfort This describes how a mattress feels. The Comfort Scale rating is based on how the cushioning materials conform to the body's shape. The higher the number the softer the mattress.

Correct Back Support System This is a general term used to describe how a mattress distributes and stabilizes body weight and maintains proper spinal alignment. Different materials provide different levels of support.

Box Spring - Foundation (optional)

  • 10 year warranty against manufacturer's defects
