Frequently Asked Questions
What does the Serenity | Plush feel like and who is it good for?
The Serenity | Plush has a soft, luxurious feel, rating as a "Plush" on our firmness scale. It’s designed to provide significant cushioning and pressure relief. This mattress is an excellent choice for side sleepers, as it cradles the shoulders and hips to maintain proper spinal alignment. It is also a great option for back sleepers who prefer a softer, more conforming surface that still offers underlying support.
How is Serene® foam different from traditional memory foam?
Serene® foam is a newer, more advanced foam designed to overcome the common drawbacks of memory foam. Its key benefits include:
Temperature Neutrality: It does not retain heat like memory foam, thanks to better airflow and integrated gel bead technology, helping you sleep cooler.
Faster Response: It recovers its shape almost instantly, so you won't get that "stuck" feeling when changing positions. This makes it easier to move around and get out of bed.
Consistent Feel: Its comfort is not dependent on temperature, so it feels consistently plush whether your room is warm or cool.
Do I need a special box spring or foundation for this mattress?
The Serenity | Plush is a hybrid mattress and is compatible with most modern foundations. You can use a platform bed, a slatted base (with slats no more than 3 inches apart), an adjustable base, or a traditional box spring/foundation that is in good condition. A solid, flat, and supportive surface is essential to ensure the longevity and performance of the mattress and to comply with the 10-year warranty.
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.
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.
