If you have your heart set on the sleigh bed it is possible to make it work.
Can i put a king mattress on a queen frame.
Check that the smallest possible setting is wider than 60 inches the width of a queen mattress.
Your queen mattress is only 60 inches wide but it is also 80 inches long.
The key to making this work is to make it look like it s intentional by turning it into a platform bed.
Then you can put your king size mattress on top of the king bed frame.
If the bed has side rails you can install the bed around a regular steel full size bed frame with that frame supporting.
Step 2 slide the rails together until the frame width is 60 inches.
Some rails are built to be compatible for queen and king mattresses in which case you can stop at this step.
Measure from one bracket to the other and note where the brackets need.
Please call us if you have any other questions.
The frame will hold your bed since it s bigger but some of the frame will be sticking out.
Install the headboard modification brackets loosely to the bed frame via the holes used to secure the headboard to the frame.
