Question: I have a full size wooden bed frame with side rails and a few wood slats. Will this product work? Is a board or box spring needed?
Document: I bought these for our spare room bed which had rails but no support system. (The rails were attached to the headboard and foot board and the bed collapsed several times) I thought they were a little pricey but they were the only thing I could find that looked like they would work for my frame without buying a whole new frame. When they came, the instructions said that they were for a wood frame. Well, I had metal, but they worked.
these adjustable slats are just what I needed for a platform bed frame I built. Slats are made so the each end of the slat is formed into a flat mount where you can either secure to a metal frame with bolts and nuts or secure with wood screws onto a wooden bed frame. Adjustable support legs two to each slat has plenty of length to be adjusted for either a lower bed frame or up to 15 inches for a raised frame. Well worth the money.
Attached easily to the wood side rails of our king sized bed. Adjustable legs can accomodate a variety of bed heights. Can be used on any size of bed from a twin to a king. Only issue was the rails were shipped taped together and the some of the black paint came off the rails when the tape was removed. Rails are under the bed and cannot be seen so it was not an issue for me.
My Cal King Bed mattress was too high with the box springs and wanted to lower the mattress without the box springs. So I  bought two set (2 each in a set) for my Cal King bed frame. I was not sure if this would work, since there wasn't too much information on Amazon about it. And also, the spec's that was posted worried me a bit too. I needed a slat that would be 73 inch wide and the spec's on Amazon stated max 66 inches.
Final product came out perfectly. No cracking sound of wood like those wooden slats when you reposition your body on the mattress. I would greatly recommend these slats and can't beat the price too. Thank You Kincaid Furniture Company for a great product and saving me a lot of headaches.
As a few others wrote, the box came looking like it had come through a war zone; but all the pieces were there and the slats were  undamaged. It took maybe 8 minutes to install and I cannot say enough about what a difference it made in my bed. I have a very old four-poster bed and a twelve year old mattress. The bed frame was fairly wobbley and I could not get regular wooden bed slats to stay in place.
We received it in a few days, it came with instructions, not that we need them, but it is alway great to review before you install it.Bolted right up to our bed, and fit prefect, no need to have your box spring hit the floor in the middle of the night. Get a bed slats, and sleep in peace.
Bought them for my bed that had wooden slats that kept falling out. This is very well constructed, easy to install, and seem to work very well, at least so far.
One commented that it would fit the Cal King bed frame, but didn't know for sure, because they used their slats for a Queen size bed frame. But I took a chance and figure if these slats don't fit my Cal king bed frame, I would either return them or sell them on Craigslist. The slats come a week later after I order it and to my surprise, these slats were easy to assemble and I had my son measure the slats.
I ordered these for under a king bed. They are really sturdy and work great. My hubby had to get his drill and some special metal screws to attach them to the bed as the sideboards were metal, I am not sure the normal person could do this. They would work great with wood sideboards without any extra work!
Answer: Hi, I purchased this item for my queen size bed and it works great.  I had to extend the slats out, so they will definitely work for your full size.  I have a platform bed with wooden slats and purchased this item for additional support.  It works very well.
