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.

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.

Adjustable beds, also known as electric beds, allow personalized comfort through a metal frame with pivot points and actuators. You can adjust the head and foot sections independently using a remote control, catering to your preferred sleeping or sitting position.

Some adjustable bases come with standard leg heights or offer a 3-In-1 design for adjustability. Others might not have height adjustment options. Our 2.0 and 3.0 adjustable bases have this 3 in 1 design so you can achieve the desired height you're looking for.

Most modern mattresses, including individual pocketed coil, hybrid, memory foam, latex, or gel, are compatible with adjustable bases. Their flexible design conforms to the movement of the base. Old style mattresses with open coils and a border wire are not compatible because the border wire won't conform to the adjustable base. It's always best to check with a representative to confirm compatibility.

At Mattress King, we understand that finding the right mattress is crucial for a good night's sleep. That's why we offer a 100-night trial policy on select mattresses. If your mattress isn't feeling comfortable, we recommend sleeping on it for at least 21 days to allow your body to adjust. However, if you're still not satisfied after this period, you're eligible to exchange it within the 100-night timeframe. For customers who purchased in-store, please revisit the store with your original receipt and our team will assist you with the reselection process, provided you have purchased our mattress protector.
