Easy Installation – Secure Support

Easy to follow instructions, see the video & PDF below. Additionally instructions are packed in the shipping carton. The “Gripper Clamp gets the job done, you simply connect the pieces together. Unique Positive-Locking designed legs actually become even more structurally solid when additional weight is applied to the bed. 3 cross rail supports are all interconnected to a center head to toe X-System. This unique feature is designed to keep the legs sturdy and in position for years to come.

One of a kind X-System

If your wooden lip measurement is lower than 6½ inches, see the SGLP-3

For Use With Wooden Side Rails Only

Glideaway’s GS-3 XS Adjustable Center Support System is built to work on wood side rails to help ensure your rails will not bend, crack, or break. Glideaway’s middle slats cross from side to side and include pre-drilled holes on each of the ends. The steel slats rest on the wooden lip and rest on your bed side rails. Simply secure them with the included screws to ensure the GS-3 XS system will not move out of position. This added support will guard against bowing, bending, and breaking of your wood bed side rails when installed properly.

    I chose this product after careful consideration – I like that it offers steel slats that won’t flex, and 3 contact points to distribute weight to the floor in the center of the bed. It’s a rock solid design. Installation was easy, and the product seems to be working well. ** Furthermore, STLBEDS was great to work with, they shipped promptly and corresponded about shipping information very quickly ** All in all, highly recommended.

    I bought a brand new bed from Macy’s and the wooden center frame broke the very first night. Well, I was in a panic and searched for something quick to replace my wooden frame. Found this product and seemed to fit my needs. I ordered the frame and in 3 days I had my new frame and it’s perfeccccttt! Now my bed is sturdy and I can tell this will last me a long time. I love my new bed and I’m so grateful to have found such a high-quality product on such short notice. Thank you!!

    Needed a new frame to replace my wooden slats that started creaking/cracking. Found STL Beds online. Originally was thinking about getting a regular metal frame. But then I saw there steel slat model GS-3 XS Center Support. It looked very sturdy and with a center support just what I needed. It took about a week for it to arrive (I live in Los Angeles). I had noticed that my mattress would kinda sink in the middle . The mattress is only 10mths old!! Apparently that was becuz the support from the wooden slats had run its course after 6yrs.With the GS-3XS steel slats they give a lot of support. My mattress now is back up to where it is suppose to be. And so comfy. I just wished I had looked around 6 months ago. This is really a good deal , don’t hesitate.

    We had our wooden slats on our bed warp. It was gradual and we didn’t realize how much they had warped. We were waking up with back issues. Finally the slats shifted and we definitely noticed. Researched online different products, this one seemed to make the most sense. Take your time setting it up, but is not too hard. I was super impressed with the design and the quality of the frame. It fixed our issue. We both woke up from a great nights sleep. I completely recommend this product. Only wish I would have found it sooner.

    Our wood frame bed didn’t come with slats so our mattress even with a box spring was sagging and noisy. I did some research and this item got good reviews. Pricing at SLT Beds was the best I could find online. Prompt communication and mailing of product. It didn’t take long to install and, wow, did it make a world of difference! Would definitely recommend product and SLT Beds!

    After waiting a few years to select and purchase a new mattress (over $2, 400), imagine my extreme disappointment when we experienced some sagging in the middle the very first night in the bed. I could not believe this was happening to a brand new box spring and mattress. My husband suggested it might be due to lack of support from the wooden slats and offered to reinforce them with larger or thicker ones. Dursing my research, I came across this bedframe and we decided the center support on this bed frame might address the problem we were having. We did have some installation difficulty due to the interior bed frame of our Amish built bed frame having trim work that surounded the slats, as a way to lock them in place. My husband had to add some trim for the new metal fram to rest on to make the metal frame sit as high as the other slats. If he had not, the box spring would have hit the higher trim pieces / slats and not seated properly on the new metal frame. This is not an issue with the frame, rather a “feature” on my bed that made installing the new metal bed frame / rails slightly more challenging. I am happy to report the sagging is completely gone and the bed feels more solid. Very happy with my purchase, since I am not certain thicker rails would have helped as much as this.

    Bought this 2 months ago for queen size Tempur-Pedic memory foam bed and a Macy’s furniture bed frame circa 2003.
    Initial install in 2003 went fine but after a move troubles started with the relatively cheap wood slats and 3 flimsy center wooden slat supports. The center supports started to fall off after repeated stresses the past few years. A real quality of life issue.

    A month ago I installed the GX-3. It was a bit more work than I thought because the bed frame did not have wooden side lips just local metal braces at each of the 3 wooden slats. So I had to remove the metal slat supports and bought 2 80 x 1.5 x .75 inch wood strips and screwed them into the bed frame to support the frame mounting of the GX-3 unit. This cost me $18 and a far amount of elbow grease. The rest of the install went smoothly thanks to the supporting video online and paper instructions shipped with GX-3.

    For the past month the bed has been rock solid and I’m happy with this product.

    My husband and I recently purchased our first complete bedroom set. I fell in love with a bed that got great reviews EXCEPT for the fact that it came with flimsy wood mattress supports. Since I knew this was going to be an issue, I went to Google to find something that would provide better support. I was led to STL Beds, and after reading reviews, purchased the GS3-XS center supports. We received the supports before our furniture arrived and could not be happier with our purchase. My husband and I set up the supports quickly without any issues. Our bed is solid and our mattress feels even more supported than with our previous bed frame. I would definitely purchase again!

  65. Douglas Belleville

    Melanie, That is great news. The GS3xs really is an outstanding center support system. I just wish these bed manufacturers would step up to the plate and include good support systems like this one instead of the junk wood ones they “give us for free” Enjoy! Doug

    Works great for converting a DaVinci convertible crib (expresso Richmond) into a full/double size bed. Strong enough to support a heavier latex mattress & box springs and 2 good sized adults. Also very strong for when toddler jumps on the bed. Daughter put this support together herself & said it was a little tricky to do, but she did it just fine.

    We are so happy with the final result of this product, and the customer service. I spoke on the phone twice with STL beds, to see if this would work with our queen frame with metal side rails. They explained that it would probably work if we were able to drill holes in to the metal side rails in order to line up with the support system. This is what we ended up doing, and the bed is so much more comfortable now! I don’t feel like I’m sleeping on the edge of a cliff because there is NO MORE SAG in the middle of the mattress. And no more squeaking, which was becoming an issue.

    I do wish there was a way this product could be adjustable, so that we could have lined up the cross bars with the holes that already existed for our original slats. It took two different sessions on two different weekends for my husband to get the holes drilled to that they lined up exactly. But he did it, and now we are very happy with this product!

We need more companies like STL who care and have pride in their service.
