Stepping Up the Comfort Technology

by Jed Harrington

Stepping up in the Sealy Posturepedic line, the Cooper Mountain offers an upgraded responsive coil system and edge support to level up on the already impressive Posturepedic technologies. The quilt features SurfaceGuard Technology with MoistureProtect offers moisture wicking to help regulate body temperature as well as antibacterial capabilities to protect your mattress over time for healthier sleep. If you prefer a firm feel, but still want the superior support offered by the Posturepedic line, this mattress is for you.

A Very Firm Support

With a comfort scale rating of 2 this is a very firm mattress as the name suggests. This is the firmest mattress in the Posturepedic collection. If you feel most comfortable on a bed that almost feels like sleeping on a carpeted floor this is a great choice.

Encased Coils Target the 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.

Cooling Gel Foam

The SealyCool Air Gel Foam quilt layer increases airflow so that heat dissipates while you sleep instead of building up and causing you to overheat.Durable Border Support

The Cooper Mountain V offers a DuraFlex Edge, a flexible coil border all the way around the mattress. This durable border offers an increase in sleepable space as you can sleep right up to the edge of the mattress.

Handles - A Simple Solution

The handles featured on the sides allow for easy installation and movement throughout the life of the mattress. This is a handy feature when moving house or rearranging your space.

Is the Ultra Firm Cooper Mountain V Right For You?

This is a great choice for back and stomach sleepers that prefer a very firm level of support.
