Queen Memory Foam Mattress in a Box

We are an innovative American mattress brand, Dyonery, dedicated to providing you with unparalleled comfort and a restful night's sleep. The goal of our brand is to seek better comfort and to be a trusted name to our customers.

Our cooling gel-infused charcoal memory foam mattress offers a fresh and clean sleep environment, thanks to the infusion of green tea and cooling gel that makes the mattress cooler and more breathable. The Dyonery adjustable bed base can help improve your overall comfort, allowing you to find the perfect angle for sleeping, reading, or watching TV. Additionally, our portable trifold mat is a great choice for both indoor leisure and outdoor travel, helping to relieve fatigue.

At Dyonery, our wish is to seek a more comfortable mattress that improves people's deep sleep. We are dedicated to solving any dissatisfaction or problem our customers may face, and we strive to address them as soon as possible.

Our queen mattress features a Graphene Jacquard Cover and a Fiberglass-Free Cover, providing a soft and breathable surface that regulates temperature and absorbs pressure. The inner cover is also fiberglass-free, offering a safe and effective flame retardant layer.

Certified by both CertiPUR-US and Oeko-Tex Standard 100, our queen mattresses are free from harmful substances, ensuring that the memory foam and fabrics have been independently evaluated to comply with all mandatory and voluntary safety standards for mattress products. These certifications give our customers peace of mind, knowing they are investing in a safe and healthy mattress.

Shipped in a compressed, rolled form in a compact box for easy delivery and setup, our 10-inch memory foam queen mattresses can be used with any type of frame, including box springs, floors, adjustable beds, foundations, slatted platforms, flat platforms, and hospital beds. Simply allow 2 hours for the mattress to fully expand to its original shape.

We are so confident in the quality of our products that we offer a 10-year limited warranty for worry-free sleep. If there are any issues with your green tea mattress, our customer support team is dedicated to assisting you and resolving the problem. Please note that our mattresses cannot be returned once opened.
