My Buying Guide on ‘Box Spring Cal King’

A box spring is an essential part of any bed frame, providing support and structure for your mattress. If you’re looking for a new box spring for your cal king-sized bed, there are a few things you need to keep in mind.

In this buying guide, I’ll discuss the different types of box springs available, the factors you should consider when making your purchase, and some of the best options on the market.

Types of Box Springs

There are two main types of box springs: innerspring and platform.
