A Good Night's Sleep

by Jed Harrington

Sealy's Essentials collection is built for a great night sleep and the Osage Firm is no exception. This durable mattress will have you sleeping soundly for years to come.

Firm Feel

Coming in at a 3 on our comfort scale, it features Sealy Support Gel Foam and Sealy Cool Air Gel Foam resulting in a flexible and breathable initial feel to offer you the contouring support you need for a sound sleep.

Responsive Coil Support

The open coil offers back support just where you need it as the coils respond to the pressure of your body as you sleep.

Is the Osage Firm Right For You?

We recommend this for back and stomach sleepers who prefer a firmer sleeping surface. If you are looking for a simple quality mattress this is a great choice.
