Question 1

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?

Accepted Answer

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.

Question 2

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?

Accepted Answer

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.

Question 3

Can this system be used under the "plastic boxes" on which a sleep number bed mattress rests?

Accepted Answer

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.

Question 4

Can the spaces between the slats be adjusted? If not what is the distance between them

Accepted Answer

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...
