The 11 Best Box Springs of 2024

Best Overall

Helix Foundation

View on Helix

A combination of materials, and design locked in the Helix Foundation as our pick for the best overall box spring. Designed with slats that are 5 inches apart, this is ideal for anyone with a memory-foam mattress who is looking to ensure there is as much airflow as possible beneath the mattress. 

While this pick requires assembly, it’s the ease and simplicity of that assembly that we appreciate. No tools are necessary, and Helix notes that it can be assembled in just two to three minutes. This is a good pick for people looking to elevate their mattress quite substantially since it’s 7.5 inches thick. However, it may be too tall for some. Our only gripe is that it comes in just one height.

This foundation has spruce wood slats, and the brand notes that it has handled up to 1,000 pounds with no visible signs of wear and tear, despite not having an official weight limit. We also appreciate the customer service: Helix offers a five-year limited warranty, in addition to a 100-night trial. 

_{Material: Wood | Thickness: 7.5 inches | Weight Capacity: 1,000 pounds (potentially more) | Assembly Required: Yes | Sizes Available: Twin, twin XL, full, queen, king, California king}

Best Budget

Wayfair Sleep Easy Assembly Box Spring

$69 at Wayfair View on Jossandmain.com

We love that this pick from Wayfair Sleep is able to provide excellent quality without breaking the bank. Available in 5-, 7.5-, and 9-inch thicknesses, you’ll find a height that suits your needs. 

It’s made from durable steel to keep your mattress supported and to prevent sagging, while also working to eliminate any squeaking. It also has a removable cover with an elastic band to make putting it on and taking it off a breeze. Inside, metal support bars are spaced 6.3 inches apart for twin and full sizes, 6.7 inches apart for twin XL, queen, and king sizes, and 7.2 inches apart for California kings.

Assembly will take longer when compared to models like the Helix Foundation, since this box spring has several more smaller pieces. It does have a slightly lower weight limit than other picks, with a 350-pound limit for a twin and a 700-pound capacity for anything above a twin. But, we appreciate the five-year warranty.

_{Material: Metal | Thickness: 5 inches, 7.5 inches, or 9 inches | Weight Capacity: 350 pounds (twin), 700 pounds (all other sizes) | Assembly Required: Yes | Sizes Available: Twin, twin XL, full, queen, king, California king}

Best Alternative

Leesa Mattress Foundation

View on Leesa

This pick from Leesa is different from a traditional box spring, but it accomplishes all of the same goals. Inside, this foundation uses 4.5-inch-spaced spruce slats that are protected by high-grade plastic molding and polyester upholstery in tuxedo grey. 

Plus, Leesa affords you the choice between a high- and low-profile model for more customizability. The high-profile model is 7.5 inches thick, and the lower profile is 5.5 inches thick.

We also appreciate that this pick comes with free shipping and returns, in addition to a 30-night trial. It also requires no tools for assembly. To top it all off, a three-year warranty should leave you feeling protected with your purchase. Just be aware that the cover is spot wash only.

_{Material: Wood, plastic | Thickness: 5.5 inches or 7.5 inches | Weight Capacity: Not listed | Assembly Required: Yes | Sizes Available: Twin, twin XL, full, queen, king, California king}

Best Low-Profile

Brooklyn Bedding The Low Profile Foundation

View on Brooklynbedding.com

If you’re looking to raise your bed without going too high, we love Brooklyn Beddings’ The Low Profile Foundation, which is 5.5 inches thick. Despite the lower height, it offers exceptional support, so you can gain precious inches to make getting in and out of bed easier while accommodating an already thick mattress. 

In addition to the thinner, more streamlined profile, this option has a sleek-looking upholstery in gray to blend into your bed frame and bedding. A five-year warranty and a simple, no-tool assembly (which apparently takes less than ten minutes!) is a nice bonus.

In addition to the wood slats, this pick features a center rail for even more support, and it’s designed to have a squeak-free, motion transfer-eliminating night of sleep. Just be aware that if your mattress is already low, and you have limited mobility, this may not be right for you.

_{Material: Wood, metal | Thickness: 5.5 inches | Weight capacity: Not listed | Assembly required: Yes | Sizes Available: Twin, twin XL, full, queen, king, California king}

Best Metal

Joss & Main OrthoTherapy Easy Assembly Metal Box Spring

View on Jossandmain.com

Sturdiness is the name of the game with Joss & Main’s OrthoTherapy Metal Box Spring. This heavy-duty option is built to last thanks to its steel construction. It’s also available in a low profile, 5-inch option, as well as a 7.5-inch option, and a 9-inch option.

On the outside of this durable pick is a polyester cover that looks great but also works for functionality, providing non-slip and elastic straps to make it super easy to use. This box spring will take longer to put together than other box springs on our list because of the smaller metal pieces. 

In addition to the sturdiness of this metal box spring, it also comes with a five-year warranty to keep you and your purchase protected. We also appreciate that this affordable pick comes with free three- to five-day delivery.

_{Material: Metal | Thickness: 5 inches, 7.5 inches, or 9 inches | Weight Capacity: Not listed | Assembly Required: Yes | Sizes Available: Twin, twin XL, full, queen, king, California king}

Best Split Box Spring

Beautyrest Foundation

$250 at Pottery Barn View on Raymourflanigan.com

If you own a split king or a split California king mattress and are looking for a box spring, this pick from Beautyrest is worth considering. Available in a 5.5-inch “low” profile model and a standard 9-inch thick model, you can really dial in your split mattress height to suit your specific demands with this option. 

Inside, it features solid steel struts and reinforced interior corner guards as well as a non-skid top to keep everything in place. Plus, from a convenience standpoint, we appreciate that it is delivered in two separate packages to make moving them into your room easier. 

But, it’s worth addressing that we find it unfortunate that this option is final sale and cannot be returned or exchanged.

_{Material: Steel | Thickness: 5.5 inches or 9 inches | Weight Capacity: Not listed | Assembly Required: Yes | Sizes Available: Split king, split California king}

Best Foldable

Zinus Jayanna BiFold Box Spring

$301 $241 at Home Depot $249 at Zinus.com $130 at Samsclub.com

While other models of box springs feature bulky designs and somewhat tedious assembly processes, the Jayanna from Zinus aims (and succeeds) at eliminating a lot of the fuss. When it comes time to assemble it, it does require tools, but the assembly isn’t particularly difficult. It’s also made from durable solid steel and comes in 4-, 5-, 7.5-, and 9-inch thickness options.

The Jayanna arrives in one single package to make transporting it easier, and if you ever need to move, the foldable design makes navigating narrow hallways and around corners much easier. 

Just be aware that sizes full through California king of this box spring have a weight capacity of 700 pounds, which is lower than other picks on our list. Zinus does offer a five-year warranty, free shipping, and a 30-day return window.

_{Material: Metal | Thickness: 4 inches, 5 inches, 7.5 inches, or 9 inches | Weight Capacity: 350 pounds (twin, twin XL), 700 pounds (full-California king) | Assembly Required: Yes | Sizes Available: Twin, twin XL, full, queen, king, split king, split California king}

Best for Heavy People

Tatago Heavy Duty Box Spring

View on Amazon $120 at Walmart

When it comes to holding a larger amount of weight, this box spring from Tatago is built differently. With a weight limit of 3,000 pounds, this pick is made from a reinforced tubular steel frame, and it includes center support bracing. The corners are also welded for additional stability.

We love that this pick is also available in 4-, 5-, 7-, and 9-inch-thick options. And as a bonus, it also comes with all the necessary tools to assemble it. It doesn’t, however, come in sizes other than full, queen, and king, making it more limited than other picks on our list. 

But we appreciate that the cover is fitted, non-woven, breathable, and waterproof. 

_{Material: Metal | Thickness: 4 inches, 5 inches, 7 inches, or 9 inches | Weight Capacity: 3,000 pounds | Assembly Required: Yes | Sizes Available: Full, queen, king}

Best Wood

Zinus Metal Box Spring with Wood Slats

$159 $146 at Amazon

We like that this pick from Zinus combines the best of both worlds, with a durable steel frame construction and wood slats to support the mattress. The 14-piece wood slat construction leaves very little space for the mattress to sag and helps to ensure there’s no weak spots for your mattress to rest on. 

For twin and full sizes, the slats are spaced 3 inches apart, while the other sizes (twin XL, queen, king, California king) are spaced 2.6 inches apart. A knitted polyester cover also keeps the frame protected.

Like other picks on our list, this option can hold 350 pounds for a twin, and 700 pounds for all of the other sizes. Keep in mind this is still on average a lower weight limit than other options. On the plus side, it’s available in 4-, 7.5-, and 9-inch thickness options to be able to accommodate any height demands. And don’t worry, all of the necessary tools to build it are included. 

One con that is worth mentioning is that the steel construction, while important for sturdiness and durability, does mean that this pick is heavy to carry in the box.

_{Material: Wood and metal | Thickness: 4, 7.5, 9 inches | Weight Capacity: 350 pounds (twin, twin XL), 700 pounds (full, queen, king, California king) | Assembly Required: Yes | Sizes Available: Twin, twin XL, full, queen, king, California king}

Best High Profile

SunPrairie Metal Smartbase

$123 at Wayfair

Whether you are struggling with your mobility or you just didn’t realize your current mattress and bed frame combo would be so short, this pick from SunPrairie is a great taller foundation. Measuring 14 inches in thickness, this base removes the need for a bed frame, acting as both a frame and a box spring. So its an affordable option for guest bedrooms or small apartments.

Don’t let the reasonable price point fool you—this option is robust, relying on a steel base to create a weight capacity of 1,500 pounds. It also comes with a skirt so you can hide anything that you’ve stored underneath the frame. 

We only wish it were available in more than queen, king, and California king sizes. 

_{Material: Metal | Thickness: 14 inches | Weight Capacity: 1,500 pounds | Assembly Required: Yes | Sizes Available: Queen, king, California king}

Best for Motion Isolation

Serta Foundation

$210 at Wayfair $500 $250 at Serta.com $250 at Macy's

If you’re sick of your partner waking you up in the night with their constant movements, the Serta Foundation is a great solution, as it’s designed specifically with motion isolation in mind. 

It helps to keep your bed partner’s movements from affecting your side of the bed. This pick also adds 9 inches of height to the bed. 

Other perks of this option include a 1,000-pound limit and a 120-night trial. You’ll also appreciate free delivery.

_{Material: Wood | Thickness: 9 inches | Weight Capacity: 1,000 pounds | Assembly Required: Yes | Sizes Available: Twin, twin XL, full, queen, king, California king}
