Frequently Asked Questions
What is the optimal coil count for a mattress to ensure proper support?
In mattresses, the optimal coil count for support has evolved. While older mattresses often had around 416 coils, modern mattress designs average around 768 coils for a queen-sized mattress. This increase in coil count enhances support and comfort, conforming more effectively to your body and promoting spinal alignment. However, it's not just about quantity; the type of coil and overall mattress design are crucial too. Higher coil counts can offer more support, especially in combination with modern mattress technologies. Do keep in mind more coils doesn't always mean better and can lead to increased pressure points so it's best to find the mattress that contours perfectly to your body and doesn't allow your body to sag or hammick in the mattress. You can read our guide to give you a better understanding
What is the Quantum Edge steel support in mattresses?
The Quantum Edge steel support in mattresses features a unique construction with narrow-diameter thicker gauge wire Quantum coils at the sides, head, and foot. This design enhances edge support, offering a firmer and more supportive edge than traditional mattresses. The Quantum Edge system replaces foam encasement, providing a sturdy seating edge and expanding the usable sleep surface. The Quantum steel narrow coils that provide the edge support allow the mattress to be a little more flexible compared to foam encased edge support when using on an adjustable base. Additionally, its design promotes 28% more airflow and breathability when comparing to a foam encased edge support, contributing to a comfortable sleep experience.
What are the benefits of a ThermoBalance® Cooling Quilt in mattresses?
The ThermoBalance® Cooling Quilt is a specialized fabric integrated into mattresses, designed to enhance sleep quality by regulating body temperature. Made from viscose derived from wood pulp, it features unique hollow fibers that naturally wick away moisture. This advanced technology helps to dissipate body heat, maintaining a thermally balanced sleep environment. Beyond its temperature-regulating capabilities, the fabric offers a soft, silky touch, adding an extra layer of comfort. The ThermoBalance® quilt ensures that you sleep comfortably without overheating, embodying a perfect blend of luxury and performance for an optimal sleeping experience.
Do I need a box spring with a metal bed frame?
Whether a box spring is needed with a metal bed frame depends on the frame's structure. Frames with minimal crossbars and a central rail typically require a box spring for added support. In contrast, frames featuring extensive crossbars (10 or more) or a wire grid usually provide sufficient support without a box spring. These frames often stand 15-19 inches high, ensuring standard bed height with a mattress. Remember, robust center support is crucial for preventing mattress sagging.

At Mattress King, we take pride in providing a personalized delivery experience. We do not use third-party services; instead, all deliveries are handled by our in-house team, fully employed by Mattress King. Our professional delivery crew arrives in branded Mattress King vehicles and wears official Mattress King uniforms.

Please note that this service does not extend to bed frames or other furniture. For us to safely remove your mattress and box springs, they must be in a sanitary condition and free of any infestations. This way, we ensure a seamless and hygienic transition to your new sleep setup.
Can you explain Mattress King's 100-Night Comfort Guarantee?
Absolutely! At Mattress King, we're dedicated to ensuring you find the perfect mattress for your sleep needs. That's why we offer an exclusive 100-night trial period on eligible mattresses. To participate in this trial, simply purchase one of our mattress protectors with your new mattress.
If you find that your new mattress doesn't quite meet your comfort needs, don't worry. We offer a hassle-free, one-time exchange for a mattress that better suits you. There are no restocking fees involved – the only cost is a minimal one-time delivery fee. It's important that exchanges are conducted through Mattress King's official delivery service to guarantee proper handling of your returned mattress.
Your trial period kicks off from the day you receive your mattress. We recommend sleeping on it for at least 21 days, as this gives your body enough time to adjust to the new sleeping surface.
