In this guide, we’ll explore everything you need to know about California King mattresses and provide tips on how to choose the perfect one for your needs.
Understanding the California King Mattress Size
The California King mattress, often abbreviated as "Cal King," measures 72 inches wide by 84 inches long. This size is four inches longer and four inches narrower than the standard King mattress, making it a perfect choice for taller individuals. The added length ensures that you have plenty of space to stretch out comfortably without your feet hanging off the edge.
Benefits of a California King Mattress
Choosing a California King mattress comes with numerous benefits, including:
- Spaciousness: With the added length, the Cal King provides generous space for individuals who need more legroom.
- Comfort: It's an excellent option for couples, as the width and length offer ample space to move around without disturbing your partner.
- Versatility: Its design suits larger master bedrooms, allowing it to become a centerpiece that adds to your room's aesthetic.
Factors to Consider When Choosing a California King Mattress
When searching for the ideal California King mattress, consider the following factors to ensure you make an informed decision:
1. Mattress Type
There are various types of mattresses to choose from, each providing different comfort levels and support. Popular mattress types include:

- Innerspring: Offers a traditional bouncy feel with excellent support.
- Latex: Provides a responsive feel with natural materials.
- Hybrid: Combines the benefits of memory foam and innerspring for optimal comfort and support.
2. Firmness Level
