## Overview

Featuring 3 heavy-duty steel cross rails and 3 adjustable legs (6"–15.5" height), it fits all bed frames and foundations, ensuring long-lasting stability. Easy to install with pre-drilled holes and included hardware, this system is the ultimate upgrade for professionals who demand durability and comfort without replacing their entire bed frame.

## Description

The revolutionary X-Brace system center support system is designed to be easily installed and help support your Full, Queen, King, or California King sized bed. Using the included legs, you can assemble this support system to adjust from heights as low as 6 inches, all the way up to 15-1/2 inches in height (measured from the floor to where the bottom of the box spring rests.) This unique center support system provides superior coverage under your bed to evenly support the box spring and mattress. The revolutionary X-System design creates a special synergy which adds an extra dimension of support to protect your bed and bedding, so you can protect your bedding investment and ensure a great night sleep. The legs of this support are easily adjustable to allow a wide range of height, accommodating almost any bed configuration. The support system also adjusts in width to fit Full, Queen, King, and California King sized beds. Designed for strong support of your bed. 3 sturdy metal rails and 3 feet hold your mattress in place. Replaces wooden bed slats. No more sagging mattress! The Positive-Locking leg design actually gets stronger when you apply the weight of the bed, with super strength to give you peace of mind. Since the three cross rails are all connected, this support stays in place over time. There are no complicated instructions to follow when installing this center support (although there are instructions in the box, just in case.) Using the unique "Gripper" Super Clamp, which comes preassembled, you can easily adjust the center support to the size of your bed and attach the pieces together to create a heavy-duty support system. The cross slats of this system have pre-drilled holes in the ends where they overlap your side rails, and are easily secured to the bed using the included screws. This ensures your center support system will not move around, and also protects your side rails from bowing or bending.

Review: Fits my King sized bed - I made the mistake of not taking a picture of what the end job looks like. Had to adjust top and bottom rail middle rail left it in its place ....all because the braces didn't line up I reused the hardware that came with my bed that is already attached to the side boards...this is strong bed frame I really feel like I will have no worries.. after installation now if you have no tools this is not for you but in order for this to work you will need all parts if you have no carpet ...that was the reason for buying this product I have no carpet. And the frame sliding on bare floor just wore them out to the point of no return .now if you have carpet I can see you getting away with out the braces..the frame will stay in place. Over all of you have bare floor you will need the whole set up and you will have to drill new holes like a did so remember if you have tools you'll need to do it right on bare floor .. carpet you can get away without the braces instructions are half clear if you're bed sit high you will need the metal leg extension I would put that together first...other than that I'm happy bed bed is solid I have no complaints for a cheap price not bad it will take you a two hours to build when you find out what all you need but to make adjustments you will need to drill 4 holes but this product is solid for my king size bed
Review: Perfect solution - This was exactly what I needed after the existing metal slats/support legs on my bed got warped and twisted after years of use on hardwood floors. (And enthusiastic adult activities...) The package came quickly, the package included everything I needed and then some. The install for me was very simple and straightforward. I did not end up needing a drill, and I was able to adjust it perfectly to fit across and height wise (the legs have extenders if you have a taller bed but I didnt need them). I was able to put this together by myself and I'm not the strongest or handiest person around. I'd recommend this product if you love your current bed frame and don't want to replace the whole thing. Which is exactly what I needed because its part of a furniture set that I was given by my grandparents :)

## Questions & Answers

**Q: I have a bed with metal side rails -- will this work with an all-metal frame? One reviewer says it won't, but the product description says it will work with both a metal and wood side boards. What's the story?**
A: This is a bit of a mixed answer - It CAN work with just about any metal frame, but it will be a lot easier with some frames compared to others. The support does include the necessary hardware to bolt to a metal frame.The tricky part is that with a wood frame, you simply screw the cross rails down where they rest. Most metal frames will have some holes pre-drilled in them along the rails, but the support may not perfectly line up with all of those holes since it has a fixed spacing between cross rails.With a metal bed frame, the options usually are:1) Rest the "lip" of the cross supports on the inside of your bed rail. Bolt down as many holes as will line up, leave the others resting. This isn't the most secure option, but will still provide good support.2) Drill 1/4" holes in your bed frame using a bit made for metal which will line up with the ends of the cross supports, so you can bolt down all six points.Using this with a metal frame is definitely possible and will provide good support, but it won't be quite as easy as using it with a wood frame.If your metal frame already has some pre-drilled holes, you may want to look at a support such as the Mighty Lift FQU-11 which doesn't have a fixed spacing - This will let you line up the cross rails with the pre-drilled holes.

**Q: Can these be screwed in directly to the wooden rails? do i need to add a bunkie board for additional support even though i have box spring?**
A: If you have a box spring no bunky board is required. I mounted my X-support system to the wooden rails that used to support the wooden slats on my bed. Used 6 wood screws to do the job, 3 to a side. My mattress is a heavy king and there are 2 box springs to support it. It all works well, no additional support needed.

**Q: Can this system be used under the "plastic boxes" on which a sleep number bed mattress rests?**
A: I would still put at least a layer of wood between the support frame and the mattress. I bought 1x10 yellow pine at Loews and covered the frame making sure the wood rested firmly on the bed frame as well. I used a regular sealy queen. I felt it gave the mattress solid support. I have a sleep number bed myself now.  Because they are such an expensive unit, I wouldn't risk damaging the mattress.  By the way, I got rid of the frame (nothing really wrong with it though) and went with the support unit with sleep number - the kind that can raise the foot and head. My back has been happy since. But I would never just put the sleep number unit on this frame without some other support - either the pine boards or plywood (3/4). Good luck.

**Q: Can the spaces between the slats be adjusted? If not what is the distance between them**
A: There are three slats; however, the space between can not be adjusted.  The only adjustment that can be made is in the width, and height.  You can adjust where you want to position the first slat with respect to the head of the bed.  The slats are screwed into the bedframe to position them firmly, and I positioned them near where the old wooden slats were, but you probable have at least 12" of adjustment as to how close to the head of the bed you want the first slat.  I hope this helps -- they worked great for me with a CAL King bedframe...

*by R***T on May 5, 2026*

Great supports. Went together pretty quick. Had no issues with it. Bed use to sag a lot in the middle and with this its like a brand new bed. Best night of sleep ive had in months. I would recommend this if you are in need of some extra support or new supports under your box spring
