Frequently Asked Questions
What is the difference between this quilted top and a smooth top mattress?
A quilted top, like the one on the Phantom, provides a more traditional mattress feel with a visible, plusher surface. It allows us to sew premium materials like wool and thick comfort foams directly into the top layer, offering immediate cushioning and thermal regulation the moment you lie down. A smooth top offers a more modern, streamlined feel that allows you to engage more directly with the memory foam layers beneath it.
What is "phase change material" in the cover?
Phase change material is an advanced cooling technology that actively manages temperature. Think of it like a smart thermostat for your bed. The material contains micro-capsules that absorb and store excess body heat when you're warm, and release that heat back to you if you get cool. This helps keep your skin at a comfortable, stable temperature for a less disruptive, deeper sleep.
Do you offer financing options?
Yes, at Mattress King, we offer a variety of financing options to fit your budget. Our partners include Synchrony, Affirm, and Snap Finance. Synchrony offers plans like 12 months with 0% interest for those with good credit. Affirm provides flexible payment terms, while Snap Finance is a great lease-to-own option for those with developing credit. You can explore and apply for these options to find the plan that works best for you.
What if I find the mattress too firm?
No problem — with our 100-night comfort guarantee, you can exchange or return the mattress risk-free if it’s not the perfect fit.
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.
