The right box spring can extend the life of your mattress, increase air flow, and improve overall support. Unlike traditional box springs made from wood frames and internal coils, a metal box spring is constructed entirely from metal and is often an open structure. These types of box springs can last for many years without breaking down or developing cracks or other defects.

There are a wealth of metal box springs available for any budget and type of mattress. So how do you choose the right model for you? I’ve tested several options for quality, support, and durability to help you find a foundation that suits your needs and personal style.

My choice for editor’s pick is the Zinus Victor 9 Inch Quick Lock High Profile Smart Box Spring and Mattress Foundation. This low profile foundation is constructed exclusively of brushed black steel and arrives ready to assemble. The Victor comes with a zippered fabric cover, assembly instructions, and a 5 year warranty.

Best Low-Profile

AmazonBasics Mattress Foundation

If you don’t need a high-profile box spring but are looking for a little supportive boost, take a look at the AmazonBasics Mattress Foundation. This streamlined, all-steel model is my choice for best low-profile box spring. The 5 inch version offers a nice bit of lift without too much height. The foldable frame comes with a zip cover and is covered by a 5-year warranty. 


  • Height options. The AmazonBasics box spring is available in either a 5 or 9 inch model, giving those of us who like a low-profile two great options
  • Assembly. This box spring comes with easy-to-understand instructions and was a cinch for me to put together — such a cinch that no tools are required
  • Works for any mattress. The AmazonBasics foundation is sturdy enough and utilizes enough slats to make it appropriate for mattresses of all kinds, including hybrids and all-foam models



  • Wide. This box spring was a tad too wide for my mattress. I suggest double-checking your measurements before purchasing 


  • Cover zipper. The optional cover is fairly easy to slide on but has a tendency to come unzipped

The Sleep Master Smart Box Spring is my top pick for durability. This 7 inch steel-frame model comes in twin-king sizes and has a weight capacity of 500 pounds. This low-profile foundation can work for any type of mattress, including all-foam models such as memory foam or latex. The Sleep Master comes with a zippered cover and limited 5 year warranty.

  • Size. The Sleep Master wasn’t quite long or wide enough for my memory foam mattress. Be sure to measure your mattress and check the Sleep Master’s dimensions before buying
  • A bit wobbly. This box spring didn’t feel quite as stable as I expected — time will tell if this is an issue of assembly or durability

How We Picked

When choosing a metal box spring, there are a few important factors to bear in mind. These are helpful to remember regardless of budget, manufacturer, or personal preferences. When checking out options, consider the following:


All-metal foundations forgo wood and other less durable materials and use steel for the frame and slats. Steel is less likely to bend or develop cracks, and may be a better choice for heavier sleepers and long-term use. When shopping for a metal box spring, look for welded steel that can stand up to the weight of your mattress and support you and a partner without warping or squeaking.


Most metal box springs can be expected to last around 5 years, but a well-constructed steel model may last significantly longer if used as intended. When you start the hunt for a metal box spring, research your top three options. Know the materials, read the reviews, and understand the fine print. Make sure you know the weight limit and warranty conditions before purchasing. Find out how long you can expect your new box spring to last, and how the manufacturer solves issues such as defects, damage, and missing parts.


Like traditional box springs made with wood and other materials, metal box springs typically range in height from 4-14 inches. When deciding whether to buy a high or low profile metal box spring, understand your sleep needs and physical abilities. Do you suffer from orthopedic pain that might make bending or sitting on a low-profile bed more difficult? How thick is your mattress? Will a high profile box spring create too much height? Think about your needs and the way you typically use your bed when narrowing down your options.


Box springs constructed from metal are some of the most durable and cost-efficient models on the market. Browse a few options that fit your wish list and note how much they typically cost. Depending on your budget, you may need to compromise in a few areas. Is easy assembly a must for you? How about a generous weight limit? With so many choices available, most folks will be able to find a metal box spring that suits the majority of their needs as well as their budget.


Metal box springs are typically available in twin to California king sizes, but dimensions may vary according to model and manufacturer. Be sure to measure your bedroom and mattress before committing to a new box spring to make sure fit won’t be an issue after purchase.

Sleepopolis Tips

Still on the fence about choosing a new metal box spring? Try the following tips:

  • Understand how you’ll use your box spring. The box spring you choose for a master bedroom may need to be more durable than one you buy for a guest room
  • Understand the warranty. Though box spring manufacturers usually offer a 3-5 year warranty, terms and conditions vary. Before purchasing, know the company policy for returns, exchanges, and repairs, as well as contact information in case you have questions or issues with your new box spring
  • Try it out. If you’re not sure which box spring is best for your needs, give some a try. Traditional box springs may have a different feel from all-metal models. Most mattress stores also have box springs, which you may be able to test out and compare
  • Don’t forget your mattress. Most mattresses are designed to be used in a way that extends their life and preserves their materials for as long as possible. Like a box spring, a mattress can be an investment. Be sure you know if your mattress requires a box spring or particular type of foundation for optimal performance
