These braces are designed to be screwed into the wooden side rails of the bed. They provide a lot of support, and don’t have the bounciness that some bed frames do. Here you can see a completely assembled rail with the parts for the next. The legs are attached with rivets and swing down. When they are in the correct position you can bolt them in place so they won’t collapse. The glides adjust by screwing them in or out, and the legs have extensions that can be bolted on in three positions for different height beds. The basic brace is for a queen bed and has two legs. For the king size there is an extension with another leg that can be bolted on. The queen version has a shorter extension without a leg to accommodate wider frames. For our bed we bolted the leg extension at the shortest position and it fit very well.

Phenomenal product !!!! Four (4) solid steel supports (rails) with three (3) support "feet" for each rail !!!! Solid as a rock. Very easy to assemble. You will NEVER have to worry about your Queen, King or California King sized bed sagging or not properly evenly supported. Nothing else like this on the market. Superior in all ways. HOWEVER, the package it comes in is HEAVY (40-50 lbs) so bring two people to carry it !!! This is the REAL deal in bed support !! A bit pricy, but in the end well worth it when you consider the total support provided and it will last FOREVER.

We got the bed frame put together & works well! Thanks for the help. It was a job to get finished, but about 3 hrs later it was finished with help from neighbor. Have to have tools to complete this assembly of bed frame!

Very sturdy and excellent quality ! Their customer service exceeded our expectations. They also sent pads to protect our floor . But to tell you the true they are not even needed since the product is designed to not damage our wood flooring.

I purchased the frame for my king size bed. When it came in it was one box that looked damaged. the box had one rail with extension piece, no legs, no screws, no instructions. i reached out to the sellers and they said they would send me the rails and parts i’m missing. Then days later said they no longer have the parts and offered a 35.00 refund! How is this a fair trade for missing more then half of the pieces of a 200.00 bed frame. The frame looks durable but i wouldn’t know because the frame is useless without all the pieces.

This bed frame has added a ton of stability and support to my mattress. It was relatively easy to install. But the company is awesome. Doug called me to make sure he was shipping me the correct product. He made a special adjustment because the height I needed which I never would have known without his phone call. His follow up was extremely helpful. He shipped the items immediately after we spoke and I received them 10 days earlier than expected. Wonderful product and excellent service.

The wood slats that came with my King bed got jacked up (bed is on wood floor and would slide, causing said jackness). STL was great to work with! They called me after I made the order to verify measurements so they could ensure the correct product was sent. The instructions were a bit difficult to decipher (instructions were a bit faded) but once the assembly commenced it went smoothly. Bed has a solid feel to it and thanks to finally finding a solution to the bed sliding on the wood floor...I'm sleeping well!

It feels so.good to have our bed back. We ordered a bedroom set from one of those big name furniture companies and two weeks in the thing collapsed on us. Turns out the feet and slats they used weren't installed correctly and they just finally buckled under our continued use. We waited THREE WEEKS trying to get ahold of their Customer Service to correct the issue but never heard back. Deciding I was tired of sleeping on the couch I caved and ordered this. I wish I would have ordered sooner. Our bed doesn't make a single sound and I feel safe and secure sleeping in my own bed again. The team over at STLBeds was great in helping me make sure I got what I needed for my bed. The slats were easy to install and fit perfect. Hopefully I don't have this issue again with wooden bed slats.. but if I do I know where to go. We have a king bed and use bunkie boards instead of a boxspring to make our bed sit lower to the ground for our dogs.. these slats and feet still worked perfectly for our setup. Highly recommended.
