Frequently Asked Questions
What does "Medium-Plush" feel like and who is it best for?
A Medium-Plush feel strikes the perfect balance between soft, contouring comfort and supportive lift. It’s ideal for side sleepers who need significant pressure relief on their shoulders and hips, as well as back sleepers who enjoy a more cushioned, body-hugging surface. If you love the feeling of sinking into your mattress just enough to feel cradled while still being properly supported, the Wave Medium-Plush is an excellent choice.
What makes the Wave mattress so effective at cooling?
The Wave mattress uses a three-part cooling system. First, the Ice Cool Knitted Cover provides an instant cool-to-the-touch sensation. Second, a layer of Gel Memory Foam works to pull heat away from your body. Finally, the Ventilated Foam Encased Edge and the pocketed coil system promote active airflow throughout the mattress core, allowing heat and humidity to escape so you sleep cool and dry all night long.
How does the zoned support system in this mattress work?
This mattress features two types of zoned support for optimal spinal alignment. The Tri-Zoned Pocket Coil System is engineered with firmer coils in the center third of the mattress to provide enhanced support under your lumbar region, preventing your hips from sinking too low. This is paired with a 7-Zone Flex Contour Foam layer above it, which has unique patterns to provide more targeted contouring and pressure relief for different parts of your body, like your shoulders and knees.
Do you offer delivery and old mattress haul-away services?
Yes, at Mattress King, we provide convenient delivery services across Oklahoma. We pride ourselves on offering fast, one-day delivery options. For those who opt for our upgraded delivery service, priced at $99, we not only deliver but also set up your new mattress and haul away your old one.

For a comprehensive understanding of our delivery services, please visit our delivery information page here.
Do you offer financing options?
At Mattress King, we offer a variety of financing options to fit your budget. Our financing partners include Synchrony, Affirm, and Snap Finance, each offering distinct plans to accommodate different financial needs.
Synchrony: For those with good credit, Synchrony provides a 12-month plan with 0% interest, helping you manage payments without additional costs.
Affirm: Affirm offers flexibility with interest rates ranging from 0% to 36%. They provide three payment term options, allowing you to choose a plan that best suits your budget.
Snap Finance: Ideal for those who might not have a strong credit history. Snap Finance considers other factors like a steady income and an active checking account. They offer a 100-day cash option and operate on a lease-to-own basis.
Each of these options is designed to make your mattress purchase more manageable financially. You can explore these options and apply directly to find the one that aligns with your financial situation.
