Expert Review by Jed
The Full XL size Simmons Beautyrest Silver Adda III Plush is an affordable mattress that offers ample space with added length for tall individuals. It has a score of 4 on our Comfort Scale, which indicates that it provides firm support along with sufficient body contouring for back sleepers and stomach sleepers. If you are a side sleeper, you will likely benefit from a softer Beautyrest model to ensure you receive plenty of pressure relief and proper spinal alignment.

This model features several improvements from the Adda II in the Recharge Collection. The first layer consists of DualCool Technology Fiber, which is an incredibly soft fiber enhanced with silver to help move heat away from the body. This fiber also prevents mold, odor-causing bacteria, and mildew to provide you with comfort that is clean and fresh. To prevent you from tossing and turning, two layers of AirCool Foam are incorporated since they provide exceptional pressure relief. AirCool Foam also features a channeled surface design that increases airflow through the mattress. A layer of GelTouch Foam is also added to offer you close contouring and deeper REM sleep. The center third includes a layer of AirCool Gel Memory Foam that reinforces support to the crucial lower back area and promotes lasting durability. Expertly engineered, the 815 Density Beautyrest Pocketed Coil System minimizes motion transfer and provides close contouring to the lower back. This system is conveniently adjustable base friendly. To ensure consistent comfort, the mattress is surrounded by a thick, ventilated edge support system that aids in moving air throughout the mattress.

To sum up, the Full XL size Simmons Beautyrest Silver Adda III Plush is an excellent choice for tall single sleepers who want a spacious medium-firm mattress.
