Serta California King Low Profile Foundation

This low-profile foundation stands at 5 inches tall, making it an ideal choice if you have a modern, thick mattress or a high-profile bed frame. By reducing the overall height of your sleep set, it makes getting in and out of bed easier while maintaining a sleek, contemporary look in your bedroom.

While often used interchangeably, this foundation is a modern box spring alternative designed for superior support. It features a solid, upholstered construction that provides a flat, rigid surface. This design is specifically engineered to extend the life of your mattress by preventing sagging and better isolating the effect of a partner’s movements during the night.

Pairing your mattress with its engineered foundation is a key step in protecting your investment. This foundation is designed to provide the specific durability and long-lasting comfort required by Serta mattresses. Using a proper, supportive base ensures your mattress performs as intended and helps maintain the integrity of the mattress over time.

This makes it an excellent solution for urban apartments or older homes with restricted layouts.

To accommodate the size and weight of a California King mattress, this foundation is designed as a "split" unit. This specific item measures 36 inches wide. Because a standard California King mattress is 72 inches wide, you will need to purchase two of these units to create a complete and stable support system for your bed.

No, this Serta foundation arrives fully assembled. You can place it directly onto your bed frame and set your mattress on top immediately, allowing you to enjoy your updated sleep setup without the need for tools or complex setup procedures.
