Frequently Asked Questions
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.
Does Mattress King Offer Old Mattress Removal Services?
Absolutely! When you opt for our upgraded delivery service, which includes setup and haul away, we take care of your old mattress and box springs. 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.
What are the dimensions of a mattress?
At Mattress King in Oklahoma, we cater to a variety of sleep preferences and space requirements with our range of mattress sizes. Here are the standard dimensions for each size, along with some special options available:
King Size: Usually measures 76 inches by 80 inches, offering ample space for couples or those who prefer extra room.
Queen Size: Typically 60 inches by 80 inches, it's a versatile choice for couples and fits well in most bedrooms.
Full Size (Double): Measures about 54 inches by 75 inches, suitable for single sleepers or smaller rooms.
Twin Size: Often 38 inches by 75 inches, great for children’s rooms or compact spaces.
Twin XL Size: Around 38 inches by 80 inches, providing additional length compared to a standard twin.
Split King: A modern option growing in popularity, especially for those interested in adjustable beds. This setup involves two Twin XL mattresses placed side by side, forming the dimensions of a King size. This configuration allows for independent positioning, enabling each person to adjust their side of the bed.
California King: While less common in this region and typically not a stocked size at our stores, the California King measures 72 inches by 84 inches. It's narrower and longer than a standard King, catering to those who need extra length.
Remember, these dimensions are standard but can slightly vary depending on the brand and specific model. It’s advisable to check the exact dimensions of the mattress model you're interested in, particularly if you have specific space constraints or bed frame sizes in mind. At Mattress King, we offer a wide selection of mattresses in these sizes, ensuring we meet diverse needs and preferences.
This comprehensive response covers the standard mattress dimensions available at Mattress King, including special sizes like the California King and Split King, providing useful information for various customer needs and preferences.
How Do Regular Profile and Low Profile Box Springs Differ at Mattress King?
When choosing the ideal foundation for your mattress at Mattress King, it's important to understand the differences between regular profile and low profile box springs. A regular-profile box spring is typically about 9 inches in height, providing a classic, elevated appearance. However, this option might make your mattress sit too high for some bed frames. On the other hand, our low-profile box springs, at approximately 4.5 inches tall, offer a more streamlined, low-to-the-ground look. This can not only enhance the aesthetic of your bed frame but also make getting in and out of bed easier, especially if a high mattress is a concern.
Despite their height differences, both types offer the same level of support and durability, ensuring a solid foundation for your mattress. The choice between a regular or low profile box spring ultimately depends on your preferred bed height and style. Whether you're drawn to a statement-making taller bed or a subtle, minimalist lower bed setup, Mattress King has options to align with your personal preference.
What's the Best Mattress for Back Pain?
Finding the right mattress for back pain is personal. Key factors are spinal alignment and pressure relief. At Mattress King, our Mattress Finder Tool helps identify the perfect fit. Invest in a quality mattress and pick a mattress with our 100-night comfort guarantee. For extra back support, consider an adjustable base. Need more advice?
