    Frequently Asked Questions

    What is an Open Coil Mattress?

    An open coil mattress features a traditional innerspring design where the coils are interconnected and not individually wrapped. This design provides strong support and a bouncier feel compared to mattresses with individually pocketed coils. However, open coil mattresses have less conforming ability and can lead to motion transfer, which might be disruptive for light sleepers or those sharing the bed. Upgrading to a mattress with individually pocketed coils can offer improved motion isolation, better contouring to the body, and a more personalized sleep experience, enhancing comfort especially for couples or those seeking more targeted support.

    What is 360-degree edge support on a mattress?

    360-degree edge support in a mattress refers to the reinforcement around the entire perimeter of the bed. This support is vital for several reasons:

    1. Preventing Sagging: It helps prevent sagging at the edges, maintaining the mattress's shape and structure over time.

    2. Increased Usable Surface Area: With strong edge support, the entire surface of the mattress becomes usable for sleeping and other activities, such as sitting. This is particularly beneficial for couples, as it allows them to use the full mattress without the fear of rolling off.

    3. Ease of Mobility: For individuals with mobility issues or those who experience back or joint pain, a firm edge support makes getting in and out of bed easier. It provides a stable base to sit on and assists in transitioning from sitting to standing.

    The construction of 360-degree edge support can vary. In some mattresses, this involves using firmer foam or high-density foam wrapped around the core mattress, providing extra support. In others, particularly in hybrid mattresses, the edge support is achieved with coils placed close to the sides.

    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.

    Do I need a boxspring or foundation for my mattress?

    Understanding whether you need a boxspring or foundation for your mattress is crucial. Often, these terms are used interchangeably, with modern boxsprings essentially acting as foundations without actual springs. The necessity of a boxspring or foundation depends largely on your bed frame.

    For Traditional Bed Frames: If your bed frame has fewer than 10 slats or crossbars, a boxspring or foundation is necessary. It provides a level, stable surface, ensuring your mattress is properly supported. This helps in maintaining the mattress's structure and can extend its lifespan.

    For Platform Beds: Many contemporary bed frames are designed as platform frames. These usually include 11 or more slats or a solid steel grid, eliminating the need for a separate foundation. Platform beds offer sufficient support for your mattress on their own.

    Adjustable Bases: The rising popularity of adjustable bases, which can raise and lower your head and feet, has also influenced mattress support. These bases are self-supporting and designed to offer optimal mattress support without needing an additional foundation.

    Importance of Proper Support: Regardless of your bed type, ensuring your mattress rests on a solid, level surface is vital. This not only helps in keeping your spine properly aligned but also enhances the overall comfort and durability of your mattress.

    Further Guidance: For more information on choosing the right foundation for your mattress and insights into various bed types, you can explore our detailed Mattress Buying Guide. Here, we also offer a range of accompanying products that complement your mattress choice, ensuring you have everything you need for a great night’s sleep.

    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.

    What is the best mattress for me?

    At Mattress King, finding the 'best mattress' is all about what uniquely suits you. Our extensive range ensures there's a perfect match for everyone's specific needs and preferences. To begin your journey to the ideal mattress, we recommend starting with our Mattress Finder Tool. This tool is designed to guide you through selecting the ideal size and budget range, helping narrow down the choices to mattresses that align with your requirements.

    But there's more to consider. Your sleep position, whether you're a side, back, or stomach sleeper, greatly influences the type of mattress that will provide the most comfort and support. Additionally, your temperature preferences – whether you tend to sleep hot or cold – play a crucial role in determining the best mattress material and design for you. And let's not forget about any specific pain points or discomfort you may experience, such as back pain or pressure points, which require tailored support and cushioning.

    Understanding these personal factors is key to finding a mattress that not only feels comfortable but also supports a healthy sleep posture, regulates temperature effectively, and addresses any specific pain or comfort needs. So, take the first step with our Mattress Finder Tool and discover the mattress that promises you the best sleep experience.

    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.
