How to change my queen bed into a king - DIY

by Deb
I have a queen and want to change it into a King. It is a large 4 poster bed like this one and came wth large supports for underneath. Would the metal slide attachment that I have seen would work for the bed rails to expand it? If not how to make it work. Even with a king the large post's would offset the extra 8" on each side. Help.

    If you can change the supports to the top of the side panels, you could place 2 plywood sheets to extend the sides. Not sure how stable it will be with the mattress sticking out on both sides. There is no way to extend the headboard and footboard. Do you have a king size mattress you're trying to make fit? I'd also check the length of the king mattress. If it's longer than this bed frame, then you will also need to remove/replace the side panels.

      @Connie Mar Since I am going to replace the queen I might as well put a king in place. It came with some supports that I have not used and plan to use them when I get ready to buy my mattress. Some one else had supports between & above the rails that I think will work. If i used 3/4 plywood cut down to 6.3 ft and cover and tape it and put on top of that... I think it would work. I was trying to find the best way without messing up my bedroom suite doing it. A Queen size is 60" wide x 80" long whereas a King size is 76" wide x 80" long.

    My brother transferred an old antique double bed I had bought in Belgium at a flea market by using 2x4's. He cut 4 and laid them on the bed. Drilled a hold on each end and then put screws in it. I just laid my queen matress on it and it works like a charm.

      @Mickie Hughbanks Hi, did you attach a piece of plywood over the top of the 2x4? Wouldn't that it would mess up the mattress where there isn't any support and start bowing? I do not want to drill any holes into my bedroom suite.

    No I did not and not it did not bow. You know it might have bee a 4x6. Anyway, it works perfectly.
