    Firm Comfort. Zoned Support. Cooler Sleep.

    The Midnight Medium-Firm Mattress is specifically designed to provide the stable, supportive surface that back and stomach sleepers need for optimal health and comfort. By preventing the hips from sinking, its 5-zone firm support system promotes a neutral spine, which can help alleviate back pain and stiffness. While its core is undeniably supportive, the Ice Cool Quilt and top comfort layers ensure the surface still feels comfortable and pressure-relieving, not hard.

    Frequently Asked Questions

    Why is a medium-firm mattress recommended for back and stomach sleepers?

    Back and stomach sleepers require a mattress that keeps their hips and spine in a neutral position. A mattress that is too soft can cause the hips to sink, leading to an unnatural curve in the lower back and potential pain. The Midnight Medium-Firm provides the necessary support to keep your body properly aligned, offering a "floating on top" feel rather than a "sinking in" feel, which is crucial for these sleep positions.

    Will a medium-firm mattress feel too hard?

    Not at all. Modern mattress design distinguishes between core support and surface comfort. While the core support layers of the Midnight Medium-Firm are robust and firm, the top layers, including the Ice Cool Quilt and gel-infused foams, are designed to provide a comfortable, pressure-relieving surface. You get the healthy support your body needs without sacrificing a comfortable feel.

    How fast is your delivery and do you offer old mattress removal?

    As your local Oklahoma mattress store, we are proud to offer fast 1-day delivery to most areas. For a nominal fee, our premium delivery service includes in-home setup of your new Midnight mattress and the responsible removal of your old mattress and foundation. We also offer a free doorstep drop-off option for your convenience.

    How does the 100-Night Comfort Guarantee work?

    Your long-term comfort is our top priority, and our 100-Night Comfort Guarantee is designed to give you complete peace of mind. To participate, simply purchase a qualifying Mattress King mattress protector with your new mattress, which helps ensure it stays in like-new condition.

    We ask that you sleep on your new mattress for at least 21 days to give your body ample time to adjust to the new support. If, after that period and before the 100th night, you find it's not the perfect fit, we invite you to come back to any of our Oklahoma stores. You can make a one-time exchange for a different mattress that better suits your needs. We never charge restocking fees; the only cost is a single delivery fee for our professional team to handle the exchange. It's our commitment to making sure you find the mattress you love.
