    • Very Sturdy

      This frame is very sturdy and well made, but if you are looking to use it without a foot board it may not did not work for me. I have an older sleigh bed and I bought this because I wanted to remove the tall footboard. Without the footboard attached the bed was not useable... felt like I was going to slide off the bed. It that is your purpose do not buy it. I kept it because one of the original wooden slats broke but I would not have bought it for that purpose, doesn't feel any different.

    • Incomplete as is - not much use for it.

      I purchased this item to use with a queen mattress, and soon found that it can not be used without purchasing the wood frame (which is not included). It does not stand alone, and after searching on for the wood frame shown in the picture, was disappointed to see that it isn't available. I ended up just returning this useless item as it couldn't be used at all. Just buy a wood frame and don't bother with this junk!!

    • Perfect

      Perfect! Instructions were a little cryptic, but we figured out how it went together by looking at it and working with it a little. The bars are sturdy and adjustable--we were nervous about fit when we ordered, the support feet are nice big round plastic pads/feet. Shipping on this item WAS AMAZING!! It made it to our door in record time. We were very impressed.

    • just what we needed

      Our bed hads wooden slats, that when we took the mattress off the bed we saw were sagging and not of the best quality. I had priced other mattress support systems and found the best value here at Overstock. This is exactly what we needed, we did not need a new mattress, we needed a better bed support. I would recommend this item to anyone looking for support for their mattress.

    • What a creeky bed needs!

      I have a wooden bed with wooden slats and used to creek every time you move around in the bed. Replaced the wooden slats with these and that immediately fixed the problem. These are very sturdy and provide great support. Easy to install too.

    • Sturdy but short

      This product is easy to assemble and sturdy enough to hold our heavy mattress. We had chronic problems with mattresses sagging in the middle before we bought this bed frame support. These three supports are plenty strong to hold any mattress. The only issue is that our bed frame, which is higher off the ground than most beds, was too tall for the supports. We had to put each support on a brick to extend the length. Overall, we're happy with this bed support

    • Sturdy and easy

      This was a very heavy built and sturdy frame. One of the L brackets was slightly pinched together, so we had to pry it apart before we could use one of the pieces, but it is tighter and works well that way. Easy assembly and I am happy that my daughter will have such a sturdy bed.

    • explain how 13484048 holds up the beds boxspring and mattress without a footboard? Since the rails are only resting in the sideboards, what is holding up the side rails and preventing the bed from flipping if you sit on foot? What stops the side rails from opening apart? rjslafayette on Aug 15, 2013

      • Hi rjslafayette, the wood framing is not included for purchase. This item only includes the metal frames. While it is possible to use this item without the footboard, you would need to be concerned about putting too much weight on the footboard side. We hope this helps. Thanks for shopping with us.

    • Does this product work without a footboard as pictured?

      • Hello rjslafayette, this should work just fine without the foot board. Thank you for shopping with us.

    • Can this product be used without sitting on the wood edge of the bedframe. My wood edge split or broke off. I want to just lay the mattress on the product for support. tp

      • Hello tp1996, This items is designed to bring a strong support to your wooden bedframe. We hope this helps and thank you for shopping with us.

    • I have my wooden head board and foot board but my side frame rails and support rails got lost in the move. is this just the middle rails or the side rails as well?

      • Hello smiles143, this is just the middle rails. Thank you for shopping with us.

    • Do these three steel rails sit on top of the wood edge of the bed frame?

      • Hello laschill, yes they will.I hope that helps. Thank you for shopping with us.

    • does this come with three rails?

      • Thank you lindylee52 for your question on the Mantua Steel Rail Bedframe Support System. Yes, it does come with 3 rails. Thank you for shopping with us!

    • What is the max weight can this frame support?

      • Thank you for contacting us, if the adjustable glides are adjusted properly, it will hold up to 1000 lbs. Please let me know if you have any further question.

    • Can I use these to replace missing rails or do I have to already have existing side rails. How does it fit a California King (which is what i need) if the longest it can go is 66" and a Cal King mattress is 84" long?

      • Thank you for your question. You would need side rails to connect this too. This will not go all the way to the bottom of the mattress but still works on the cal king mattresses.

    • How does middle lock? Have King bed will need to adjust for king.

      • There is a picture on the page that you can see how it locks,I hope that helps.

    • "Dimensions: 7.5-12 inches high x 46-66 inches long" Does this mean that the E-Clamps are adjustable in height?

      • We are currently looking into this and will post an answer shortly.

    • Are the dimensions listed (46-66 inches long) accurate? The product states support for King (76 inch wide). Therefore, the dimensions should be more than 76" long to mount the side of the bed. Either the max length (66 inch) is incorrect or the products supported (up to King) is incorrect. Can you please confirm the product will work with a King bed?

      • The dimensions listed actually mean that it fits a full size bed (Full size mattress size is 4?6?), up to and including a King size (6?6?). The rails are adjustable so they are able to fit a Full, Queen or King frame. The rails (3 per carton) actually go side to side, not head to foot. The legs are adjustable.

    • Can this be used on a metal bed frame to offer support of heavy box spring and mattresses in the middle to avoid sagging?

    • Is this a queen size frame?

    • Item #: 13484048 Interested in full size bed frame. Can this be reduced to a twin bed frame? It features a head board, does it come with it and what is the material?

      • This can only be sized to Full, Queen, King and Cal-King. The headboard is not included and the material is rustproof rail steel and zinc plated steel. We hope this info is helpful.
