Frequently Asked Questions
What is Titanium-Infused Memory Foam?
Titanium-infused memory foam is an advanced material that enhances traditional memory foam in two key ways. First, the infusion of titanium particles adds strength and durability to the foam's cell structure, helping it resist body impressions over time. Second, titanium is an excellent thermal conductor, which means it helps pull heat away from your body more efficiently, resulting in a cooler and more comfortable sleep.
What makes the PowerEdge® support on this mattress special?
The PowerEdge® support system is an intelligent design that reinforces the most important parts of the mattress edge. It features two dedicated rows of extra-thick, heavy-gauge steel coils running head-to-toe along both sides of the mattress. This targeted reinforcement provides a firm and stable edge, which has two major benefits: it prevents that 'rolling-off' feeling, maximizing your usable sleep surface, and it creates a durable seating edge for getting in and out of bed.
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.
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.
