Featuring patented X-System technology and a super clamp, it prevents bed frame legs from sliding or bending, ensuring superior mattress and foundation support. With easy installation and height adjustability from 6.5 to 15.5 inches, it’s compatible with wood and metal frames, providing a durable solution to eliminate sagging and extend your bed’s lifespan. ## Description The revolutionary X-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 6-1/2 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.) 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, you easily attach the pieces together to create a heavy-duty support system. 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. 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 supoprt to protect your bed and bedding, so you can protect your bedding investment and ensure a great nights' 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. The X-System Adjustable Center Support System is designed for use with both Wooden and Metal side rails, and is a great way to ensure your rails will not bend or break. 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. ## Features - UNIVERSAL FIT: Suitable for Full / Double, Queen, King / Eastern King, and California King size Beds; Works with Mattresses, Box Springs, and Foundations; Compatible with steel, iron, metal, and wood bed frames (bed frame not included) - STRONG SUPPORT FOR BEDS: Patented X-System keeps bed frame legs vertical and in place, preventing them from sliding out of position; All-steel cross rails combined with heavy-duty super clamp and X Support provide the ultimate in support for your bed, foundation, and bedding; Stronger alternative to bed slats; No more sagging mattress! - EASY TO USE: Clear, uncomplicated instructions are included; Pre-drilled holes allow you to easily secure the cross slats to your bed using the included screws ## Technical Specifications | Specification | Value | |---------------|-------| | Display maximum weight recommendation | 200 Pounds | | Care instructions | Wipe with Dry Cloth | | Batteries required | No | ## Images ![Glideaway X-Support Bed Frame Support System, GS-3 XS Model - 3 Cross Rails and 3 Legs - Strong Center Support Base for Full, Queen and King Mattress, Box Springs, and Bed Foundations - Image 1](https://m.media-amazon.com/images/I/71t9L-ZXhuL.jpg) ![Glideaway X-Support Bed Frame Support System, GS-3 XS Model - 3 Cross Rails and 3 Legs - Strong Center Support Base for Full, Queen and King Mattress, Box Springs, and Bed Foundations - Image 2](https://m.media-amazon.com/images/I/51JQFQSHgkL.jpg) ![Glideaway X-Support Bed Frame Support System, GS-3 XS Model - 3 Cross Rails and 3 Legs - Strong Center Support Base for Full, Queen and King Mattress, Box Springs, and Bed Foundations - Image 3](https://m.media-amazon.com/images/I/61y3Mcd+QCL.jpg) ![Glideaway X-Support Bed Frame Support System, GS-3 XS Model - 3 Cross Rails and 3 Legs - Strong Center Support Base for Full, Queen and King Mattress, Box Springs, and Bed Foundations - Image 4](https://m.media-amazon.com/images/I/61UdZNVTUzL.jpg) ![Glideaway X-Support Bed Frame Support System, GS-3 XS Model - 3 Cross Rails and 3 Legs - Strong Center Support Base for Full, Queen and King Mattress, Box Springs, and Bed Foundations - Image 5](https://m.media-amazon.com/images/I/51+tNOMdIoL.jpg) ## 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... ## Frequently Bought Together - Glideaway X-Support Bed Frame Support System, GS-3 XS Model - 3 Cross Rails and 3 Legs - Strong Center Support Base for Full, Queen and King Mattress, Box Springs, and Bed Foundations - ZINUS Compack Fabric Covered Wood Slats, Bunkie Board, Box Spring Replacement, Natural, King --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/304509200-glideaway-x-support-bed-frame-support-system-gs-3-xs](https://www.desertcart.co.uk/products/304509200-glideaway-x-support-bed-frame-support-system-gs-3-xs) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-21*
