Frequently Asked Questions
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.
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. In addition to this, we offer a free delivery option that includes doorstep drop-off, similar to services provided by FedEx and Amazon. This option is great for those who prefer a contactless delivery to their front porch or door. For a comprehensive understanding of our delivery services and to find the best option for your needs, please visit our delivery information page here.
I sleep with a partner. How well does this mattress isolate motion?
The Churchill is excellent for couples. It uses an individually pocketed coil system, which means each of the 768 coils can react independently to pressure. When your partner moves or gets out of bed, the movement is absorbed by the individual coils directly beneath them instead of transferring across the entire mattress. This ensures you can enjoy a much more peaceful, undisturbed night's sleep.
What kind of bed frame should I use with this mattress?
To ensure the best support and longevity for your Churchill hybrid mattress, we recommend using a modern foundation, platform bed, or an adjustable base. A solid, flat surface is key. If you are using a slatted frame, please ensure the slats are no more than 3 inches apart to provide adequate support and comply with the warranty.
How does copper-infused latex help?
Copper-infused natural Talalay latex combines the buoyant support of latex with the health benefits of copper. It naturally resists bacteria, mold, and dust mites, while also conducting heat away from your body. The result is a hypoallergenic, cooler, and cleaner sleep surface that helps you rest more comfortably night after night.
