For a split adjustable bed in King size, which typically consists of two Twin XL mattresses, the ideal choice is a set of Split King sheets. These sheets include two Twin XL fitted sheets to accommodate the independent movement of each side of the adjustable bed, along with one King size flat sheet for complete coverage. Additionally, consider a Split King mattress protector set, comprising two Twin XL mattress protectors, to ensure complete protection and comfort for your adjustable bed setup.

A Split King adjustable bed is an ideal solution for couples who want independent control over their sleeping positions while still enjoying the spaciousness of a king-size bed. This setup involves two Twin XL adjustable bases and mattresses placed side by side, creating the dimensions of a standard king bed. This unique configuration allows each person to adjust their side of the bed independently, offering personalized comfort. Split King beds are also complemented by specialized bedding, known as split king sheets, which include two Twin XL fitted sheets and one king flat sheet, ensuring a seamless look and feel.

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.

The primary difference between Twin and Twin XL mattresses lies in their length. A standard Twin mattress measures 38 inches in width and 75 inches in length. In contrast, a Twin XL mattress has the same width of 38 inches but offers an additional 5 inches in length, totaling 80 inches. This extra length in the Twin XL makes it a suitable choice for taller individuals or for use in college dorm rooms, where extra legroom can be particularly beneficial. Both sizes are often used in smaller bedrooms, guest rooms, or for children's beds, but the Twin XL's extra length can provide more comfort for growing teens and adults.

No, a box spring will not work with an adjustable bed. The design of an adjustable bed is self-supporting, offering all the support your mattress needs. This setup ensures proper mattress support and function while using the adjustable features.

Yes, adjustable bases fit standard dimensions and can comfortably sit inside a bed frame. If your frame has slats, they should be removable so the adjustable base can rest inside the cavity of you bed frame. Optional headboard brackets are available for attaching a standalone headboard.

At Mattress King, the adjustable bases are not eligible for a trial period. Additionally, we do not offer a specialized return policy for these items beyond our standard return policy. It's important for customers to carefully consider their purchase of an adjustable base, as the standard return policy terms will apply. We encourage customers to review our standard return policy here for more detailed information and to ensure clarity on the conditions and processes involved.

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.
