A 2-inch king box spring is a slim mattress foundation for beds that need support without much added height. It can be useful for recessed platform frames, bunk beds, daybeds, or a setup with a taller mattress. The most important checks are whether the foundation fits your frame, whether the frame has center support, and whether the foundation works with your mattress. Here are five metal options, compared by their listed features.

Our Picks: Best 2 Inch Low Profile Box Spring King reviews
1. ZASHONT: A Covered Foundation with Listed Dimensions
The ZASHONT is a 2-inch metal foundation with a fabric cover. Its thin profile is meant to add support without raising the mattress much, making it a possible fit for recessed frames or beds that already sit high. The listing describes a non-slip design and a removable, machine-washable cover.
One useful detail is its stated size: 79.6 inches long by 75.6 inches wide, for a mattress listed as 80 by 76 inches. That is slightly smaller than the mattress dimensions, so measure your frame and check the fit before ordering rather than assuming all king frames have the same interior space.
The integrated design, included tools, and instructions are intended to make setup straightforward. The listing also describes the frame as heavy-duty steel and designed for quiet use, but it does not provide a weight-capacity figure. Compared with options that list a capacity, this one offers less information for shoppers who want to compare load limits.
Pros:
- Only 2 inches high for a low-profile setup
- Removable, machine-washable fabric cover
- Specific dimensions are provided in the listing
- Tools and instructions are included
Cons:
- No weight-capacity figure is provided in the supplied details
- Its listed dimensions may not suit every king frame
Verdict: Choose the ZASHONT if you want a slim, covered foundation and its listed dimensions match your bed frame.
2. LUMUNANCE: A Simple Metal Base for Multiple Mattress Types
The LUMUNANCE is a metal king foundation with a 2-inch profile. Its listing says it can support spring, latex, and hybrid mattresses, which makes it a flexible option if you are choosing a foundation for one of those mattress types. Confirm compatibility with your mattress maker and bed frame before purchasing.
A removable cover is included and is described as suitable for spot cleaning. The listing also emphasizes sturdy steel construction and includes tools, hardware, and instructions for assembly. It advises tightening all screws during the final steps, a practical reminder for keeping the frame properly assembled.
Unlike some of the other choices here, the supplied details do not state exact foundation dimensions, a weight capacity, or rounded corners. If your bed frame has a tight inset, those missing specifics matter: check the product’s current size information and compare it with your frame before deciding.
Pros:
- 2-inch low-profile design
- Listed for spring, latex, and hybrid mattresses
- Removable cover for spot cleaning
- Assembly tools, hardware, and instructions are included
Cons:
- The supplied details do not specify a weight capacity
- Exact dimensions are not included in the supplied description
Verdict: The LUMUNANCE is worth considering if you want a basic metal foundation and can confirm its dimensions and fit before ordering.
3. Awesofurni: Rounded Corners and a Listed 3,000-Pound Capacity
This Awesofurni foundation is a 2-inch metal option designed for low-clearance setups, including inset or drop-in platform frames. Its rounded corners are intended to reduce the chance of bumping into sharp frame edges. The listing states a capacity of up to 3,000 pounds; treat that as the manufacturer’s stated figure and make sure your whole bed setup is compatible.
The foundation uses reinforced steel construction and metal slats. Its listing describes welded support points intended to reduce distortion and squeaks, and a removable fiber cover with elastic bands for cleaning. Tools are included for assembly, and the product is presented as an integrated design.
Compared with the ZASHONT and LUMUNANCE, this option offers a clearly stated capacity and rounded corners, but the supplied description does not give exact dimensions. For a king frame with inset rails, verify the fit carefully before ordering. The 2-inch height also means it is not intended to add the lift of a traditional taller box spring.
Pros:
- 2-inch profile for low-clearance beds
- Manufacturer states a capacity of up to 3,000 pounds
- Rounded corners and removable cover
- Tools are included for assembly
Cons:
- Exact dimensions are not included in the supplied details
- Its slim profile adds little height to the mattress
Verdict: Pick the Awesofurni if rounded corners and a stated load capacity are priorities, provided its frame dimensions work for your bed.
4. VIPSHOW: A Low-Profile Choice That Requires Center Support
The VIPSHOW is a 2-inch metal foundation with rounded corners. Its listing describes widened and thickened steel support pillars, a slot system for the slats, and a capacity of up to 3,000 pounds. It is listed for use with innerspring, memory foam, and latex mattresses, and for bunk beds, daybeds, and embedded or drop-in platform frames.
A key fit requirement stands out: the product description says the bed frame must have a center support rod to help prevent sagging. Measure the inside of your frame and compare it with the product’s size chart before ordering. This is especially important for a king-size setup, where frame construction and support can vary.
The slot-mounted slats are described as a way to reduce friction and noise. Assembly tools and instructions are included. This model has more specific frame guidance than some alternatives, but it is not a good match for a bed frame without the required center support.
Pros:
- Manufacturer states a capacity of up to 3,000 pounds
- Rounded corners and a low 2-inch profile
- Listed for several mattress types
- Tools and instructions are included
Cons:
- Requires a bed frame with a center support rod
- The supplied details do not state exact dimensions
Verdict: The VIPSHOW can suit a compatible frame with center support, but measure carefully and do not skip that requirement.
5. Kaelidra: 13 Slats and a Stated 3,500-Pound Capacity
The Kaelidra is a 2-inch steel foundation with 13 reinforced slats. Its listing states a capacity of up to 3,500 pounds and describes U-shaped channels intended to reduce metal-on-metal friction. Rounded corners are another useful design detail for bedrooms where people may brush against the bed frame.
The slim height is aimed at bunk beds, daybeds, recessed platforms, and other setups where a taller foundation may not fit. The listing says the parts are packed together and describes assembly as straightforward. It also specifies that the bed frame should include a center support bar and recommends checking the frame’s inside dimensions against the size chart.
The main caveat is availability: the supplied product data marks this item as unavailable. Availability can change, so check the listing before planning around it. If it is unavailable when you shop, the Awesofurni and VIPSHOW also state capacities, though their listed maximum is lower.
Pros:
- 13 steel slats and a stated capacity of up to 3,500 pounds
- Rounded corners
- 2-inch profile for low-clearance beds
- Slat channels are designed to reduce friction
Cons:
- Marked unavailable in the supplied product data
- Requires a bed frame with a center support bar
Verdict: Consider the Kaelidra if it is available and your frame has center support; otherwise, compare the other options that list capacities.
How to Choose a 2-Inch Low-Profile King Box Spring
Measure Your Bed Frame’s Interior
Do not rely on the word “king” alone. Measure the inside length and width of your frame, especially if the foundation will sit inside a recessed opening. Compare those measurements with the foundation’s size chart or listed dimensions. The ZASHONT provides dimensions in its supplied details, while several of the other listings do not, so check the product page for the measurements before buying.
Check for Center Support
Some king-size frames need center support to help carry the mattress and foundation. The VIPSHOW and Kaelidra listings specifically require a center support rod or bar. Check your frame before choosing either one. If the product description gives a support requirement, follow it rather than assuming the foundation will work with any bed frame.
Confirm Mattress Compatibility
Foundation compatibility can depend on your mattress type and the mattress maker’s guidance. The LUMUNANCE listing names spring, latex, and hybrid mattresses; the VIPSHOW listing names innerspring, memory foam, and latex. Check your mattress instructions or warranty guidance as well, since a foundation that fits the frame may not automatically be the right support for every mattress.
Decide How Much Height You Want
A 2-inch foundation adds only a small amount of height. That can help when a mattress is already tall or a frame has limited clearance, but it will not raise the bed as much as a taller box spring. Consider the combined height of the frame, foundation, and mattress before choosing a low-profile model.
Compare Capacity Claims Carefully
Some listings state a maximum capacity, while others in this group do not provide one in the supplied information. The Awesofurni and VIPSHOW list up to 3,000 pounds, and the Kaelidra lists up to 3,500 pounds. These are manufacturer-stated figures, not a guarantee that every bed-frame and mattress combination has the same capacity. Check the requirements for your complete setup.
Think About Covers, Corners, and Assembly
A removable cover can help with cleaning, while rounded corners may be useful if the bed is in a tight space or people often walk close to it. Assembly details also vary: several listings include tools and instructions, but setup still requires following the supplied steps and tightening the hardware as directed. Choose the features that matter for your room rather than treating them as substitutes for proper fit.
Frequently Asked Questions
What does “2-inch low profile” mean?
It means the foundation is about 2 inches high. It is designed to provide a support base while adding little height to the mattress, unlike a taller traditional box spring.
Will a 2-inch king box spring fit any king bed frame?
No. Frame dimensions and support designs can vary. Measure the interior of your frame and compare it with the product’s listed dimensions or size chart before ordering.
Do these foundations work with memory foam mattresses?
The VIPSHOW listing names memory foam as compatible. Other listings give different compatibility details or do not specify memory foam. Check the product information and your mattress maker’s guidance before choosing.
Does a king foundation need center support?
It depends on the foundation and bed frame. The VIPSHOW and Kaelidra listings specifically call for center support. Check your frame and follow the requirements for the model you choose.
Can I use a 2-inch box spring to make my bed taller?
It adds about 2 inches, so it provides only a small lift. If you want a noticeably taller bed, a 2-inch foundation may not meet that goal.
Are the covers removable?
The ZASHONT listing describes a removable, machine-washable cover, while LUMUNANCE describes a removable cover for spot cleaning. Awesofurni also lists a removable cover. Check the care instructions for the specific model you buy.
Final Recommendation
For a covered foundation with dimensions stated in the supplied details, the ZASHONT is a practical place to start, as long as it fits your frame. If a stated capacity and rounded corners matter more, compare the Awesofurni and VIPSHOW, paying close attention to frame fit and the VIPSHOW’s center-support requirement. The Kaelidra lists the highest capacity in this group, but it is marked unavailable in the supplied data. Whichever model you choose, measure your frame and confirm mattress compatibility before ordering.
