Kingsdown Twin XL 3" Foundation

This 3-inch foundation is specifically designed for modern, thicker mattresses. By lowering the overall height of your sleep set, it creates a sleek, contemporary look and makes getting in and out of bed more accessible. It is an ideal choice for households that want the robust support of a traditional base without the excessive height of a standard foundation.

Absolutely. This Twin XL foundation is the standard building block for a split-king setup. By placing two of these units side-by-side, you create the exact dimensions of a standard King bed (78"W x 80"L). This is a highly functional solution for those using two separate mattresses for customized comfort or for easier transport into homes with narrow entryways.

To maintain the upholstered finish, our experts recommend regular vacuuming with an upholstery attachment to remove dust and allergens. For minor spills or stains on the fabric, you can lightly spot clean using a soft cloth with mild soap and water. Always ensure the area air dries completely to protect the premium Canadian Spruce frame underneath.

This foundation is meticulously hand-assembled using sustainably sourced Canadian Spruce. To ensure longevity, the lumber is both heat-treated and kiln-dried. This specialized drying process removes moisture from the wood, preventing it from warping, shrinking, or cracking over time, which ensures the base remain level and stable for years to come.

This foundation features wooden slats that are placed more closely together and cut a full inch wider than the industry standard. This design provides a sturdier, more uniform support system that helps maintain the structural integrity of your mattress and protects your warranty.

This is an excellent choice for students and urban dwellers. Its Twin XL dimensions are tailored to the "Extra Long" twin beds standard in most college dorms. Additionally, the slim 3-inch profile and fully assembled design make it much easier to maneuver through narrow hallways, small elevators, and tight staircases than a bulky, standard-height box spring.
