You asked and we answered. In today’s blog, we’re covering everything you need to know about box springs so you can make smart mattress buying decisions.

What Do Box Springs Do?

Box springs perform some important functions, which can help protect your mattress for years to come. First and foremost, box springs provide a stable base for the mattress. Innerspring mattresses especially benefit from this base, which prevents sagging, reduces wear and tear, and can even increase the life span of the mattress. They also keep the mattress off the floor, which can help prevent dust particles, dust mites, and bugs from infiltrating the mattress. Many people don’t realize that some mattress warranties specify recommended box springs or foundations for the mattress, and by choosing not to use them, you could be voiding your warranty.

Are Box Springs Necessary?

It depends on the mattress and the bed frame. Many newer mattresses no longer require box springs. Memory foam mattresses, for example, don’t necessarily require box springs, though many people choose to use some sort of box spring or foundation for added height. If you have a solid or slatted platform frame, this can be sufficient support for many mattresses. Similarly, adjustable bases do not require box springs, assuming you are using a mattress that that is approved for adjustable beds. Regardless of what type of mattress or bed frame you choose, keep in mind that some mattress warranties are void if you fail to use the mattress on the recommended base, so you should check your warranty before making any decisions.

Are All Box Springs the Same Height?

No. Just like mattresses, box springs and mattress foundations are available in different heights so you can choose the style that works best for you. Standard box springs are 9 inches tall, while low profile box springs tend to be on the shorter side—usually between 5 and 6 inches. The box spring height does not affect performance or mattress support but tends to be an aesthetic preference. If you like a modern, sleek look, a low-profile foundation may be right for you. It can also be a great option for people who have trouble getting in and out of bed.
