The Sealy Essentials Osage Firm Twin XL Mattress provides an exceptional night's sleep. It is designed to last for years without losing quality.
The euro top includes layers of SealyCool Air Gel Foam and SealyCool Gel Foam Firm to provide just enough pressure relief with flexible, durable support. The comfort scale rating of 3 indicates a mattress that is on the firm side but does not feel like you are sleeping right on a carpeted floor.Advanced Type of Support
Sealy's Response Pro Encased Coil is an elevated coil system that offers just the right support exactly where you need it. The coils each respond individually to your body's curves allowing for targeted support. The individually encased coil system reduces motion transfer allowing you to sleep soundly even beside a restless partner. The Gel Foam in the center third offers extra support in the middle section where it's needed most.Airflow For Ideal Temperature
The Layer of SealyCool Air Gel Foam in the quilt offers increased airflow through the mattress as you sleep allowing for a cool and comfortable sleeping temperature.Making the Most of the Mattress
