The 6 Very Best Box Springs

A good box spring should do a few things: improve airflow, provide support for your mattress, and raise it to a more comfortable height. And with so many types of box springs out there — including metal box springs, wooden box springs, and even box springs that fold — it can be hard to pick the right one for you. So we’ve rounded up the best of the best, as praised by the most enthusiastic reviewers on Amazon. To even the playing field a bit, we focused on queen-size box springs, but most of these box springs and mattress foundations are available in other sizes as well. And don’t worry, if you’re looking for other ways to help you get a good night’s sleep, we have roundups of the best mattresses, adjustable bed bases, and platform beds, too.

What we’re looking for

Depth: Box-spring height depends on your preference and your mattress height, and many box springs come in a variety of heights. If you like your bed closer to the ground, you’ll want a low-profile bed frame around four or five inches tall. If your mattress and bed frame already have your bed lifted pretty high up off the ground, you may want to stick with a lower box spring so you don’t have to literally jump into bed each night. And if you are an older person or have limited mobility, a lower box spring may be best for you. But if you like feeling lifted, you’ll want to go for something that’s seven or nine inches. We’ve flagged the most popular height for each of our picks, along with the other variations.

Price: There are three different price points that we decided on, denoted as $, $$, or $$$: respectively, under $150, under $200, or over $200. The prices shown are for the mattress heights named in the product title — those heights are the ones readers bought most.

Best overall box spring

5-inch, 7-inch, and 9-inch | $

Zinus makes some of our favorite affordable but high-quality mattresses and bedroom furniture, so it’s no surprise it’s also behind several of our readers’ favorite box springs — five of the six on this list, in fact, including this best overall nine-inch box spring. Since 2019, readers have purchased it 3,788 times, which is exactly double the amount of our second-most-sold box spring. It has more than 52,000 five-star reviews on Amazon, too, with many noting it’s strong, study, and surprisingly supportive even after years of use. The strength comes from the quality of the metal, a durable steel that can support up to 700 pounds. (The steel frame is covered by soft-knit polyester.) Like all Zinus furniture, it’s easy to put together, with many noting it took less than an hour to do alone and even less when done with someone else. And if you want to spend a little less, you can get it in a low-profile five-inch height, which was technically our second-most-sold mattress with 1,894 sold. But since they’re part of the same line, we’ve wrapped them into one here and named it the best overall (and least expensive).

Best metal box spring

From $206

4-inch, 7.5-inch, and 9-inch | $$$ 

For an even sturdier metal box spring, readers and Amazon shoppers like this one from Zinus. It has more steel slats running the length of the bed than the Amita box springs above, with about three inches between each. If more slats sounds like more work to you, think again: This one uses Zinus’ Quick Lock assembly system, which means the slats snap into place — no screws needed. Even without the use of screws, though, the box spring can support up to 700 pounds, and it’s earned much praise from Amazon reviewers, about 6,500 of whom have given the box spring a five-star rating. Many of those reviewers comment that they put the box spring together in 20 to 30 minutes, and once assembled, it didn’t budge, squeak, or let the mattress sag. That durability is why it’s also our third-most-purchased box spring, with just under 1,000 sold since 2019.

Best box spring with wood slats

4-inch, 7.5-inch, and 9-inch | $$$

For those who prefer wood slats, Zinus is the reader pick again. Readers purchased this box spring over 900 times since 2019, making it our fourth-most-sold. It combines the strength of steel in the base with the natural yet sturdy bend of wood in the slats, which some sleepers say offers a more comfortable night’s rest. While wood can be less durable than steel, this box spring holds up. The slats are spaced close together (about three inches apart) for maximum sturdiness and support, and they’re strung together so you don’t have to worry about spacing them correctly — just unroll the bundle and lay them on the box spring’s frame. And as with all Zinus products, this one is praised for how easy it is to assemble. Many of the 11,000 shoppers who gave the box spring a five-star rating on Amazon say it takes mere minutes to assemble.

Best low-profile box spring

4-inch and 8-inch | $$$

If you don’t want your bed too high off the ground, a few inches in your box spring’s size can make a world of difference. This one from Zinus is available in as few as four inches, and many of the over 3,500 people who gave it five stars on Amazon have noted how surprised they are that it’s so thin and lightweight yet so sturdy. It’s made of solid wood, both the base and the slats, though the slats are made of thicker wood than most to ensure a solid base. Many reviewers who didn’t want to literally climb into bed appreciate the low base, as do the 746 readers who purchased this box spring in the past three years, making it our fifth most-sold.

Best easy-to-assemble box spring

From $109

5-inch, 7-inch and 9-inch | $

While Zinus is (obviously) beloved, Amazon takes the prize for the easiest-to-assemble metal box spring. Nearly 70 percent of the almost 20,000 Amazon shoppers who have purchased this box spring used the phrase “easy to assemble” in their review: No tools are required to put this interlocking box spring together. It more or less snaps together in six easy steps — and the whole thing takes about 20 minutes, according to reviewers. But the durable steel frame and horizontal slats provide a sturdy, quiet base.

Best upholstered box spring

4-inch, 7.5-inch, and 9-inch | $

For those who want a put-together look from their quilt all the way down to their box spring, this upholstered box spring from Zinus offers a crisp, clean design in a — you guessed it — sturdy package. Readers bought it more than 300 times since 2019, making it our seventh-most-sold box spring. It’s made of strong steel for the base and thick, 2.8-inch wood for the slats, but that’s all hidden beneath a gray woven fabric cover for a polished look. As some reviewers note, that means even when their box spring peeks out from under the covers or there’s no bed skirt, it looks okay. And of course, it’s easy to assemble, with a base that comes together in steps. The wood slats are encased in a fabric covering that makes them even easier to roll out onto the frame.
