    Frequently Asked Questions

    What makes GELTEX® foam different from latex or memory foam?

    GELTEX® is a high-performance comfort foam that combines the best qualities of different materials. It has the responsive, buoyant, and almost "bouncy" feel of latex, which makes it easy to move on the mattress. However, it is engineered to provide superior pressure relief and durability compared to many foams. For the sleeper, this means you get a gentle lift and support without the slow-sinking feeling of traditional memory foam.

    How does the cooling technology in this mattress actually work?

    The Serenity Hybrid uses a multi-faceted approach to cooling. The primary technology is the PCM (Phase Change Material) woven into the cover. PCM is a smart material that actively absorbs and releases body heat to maintain a balanced and comfortable temperature throughout the night. This is supported by breathable comfort layers like Serene® and GELTEX® foam, which have an open-cell structure that promotes airflow and prevents heat from getting trapped, unlike traditional memory foams.

    Is a hybrid mattress a good choice for me?

    A hybrid mattress is an excellent choice for a wide range of sleepers, especially those who want the "best of both worlds." You get the contouring comfort and pressure relief from the top foam layers (Serene® and GELTEX®) combined with the durable support, breathability, and edge-to-edge stability of an innerspring coil system. If you like the cushioning of foam but don't want to sacrifice the traditional support and airflow of a spring mattress, the Serenity Hybrid is a perfect fit.

    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.

    What are the dimensions for standard mattress sizes?

    Choosing the right size is a key part of finding the perfect mattress. Here are the standard mattress dimensions to help you measure your space and decide which size is best for you. This mattress is available in most of the sizes listed below.

    • Twin: 38" x 75" — Ideal for children, bunk beds, and single sleepers in smaller rooms.
    • Twin XL: 38" x 80" — A great choice for taller teenagers or for use in college dorms. Two Twin XLs also form a Split King.

    • Queen: 60" x 80" — The most popular mattress size, providing comfortable space for couples or a luxurious amount of room for an individual.
    • King: 76" x 80" — The widest standard size, perfect for couples who want maximum personal sleeping space
    • California King: 72" x 84" — Offers extra length for taller individuals, though it is slightly narrower than a standard King.
