Step 1 inspect your bed to see how the frame attaches to the headboard and footboard.
Can you put a full size mattress on a queen bed frame.
After removing the queen size mattress and box spring push the frame inward from the foot of the mattress support to adjust its length to 75 inches.
The difference in width between a full size and queen is only six inches so there will only be a three inch overhang on both sides.
A full sized mattress and a queen sized mattress have a width difference of about six inches.
A standard queen size mattress is approximately 60 inches wide by 80 inches long according to the better sleep council.
You do not have to adjust the bed frame very much.
Queen headboard and or footboard usually measures 60 inches wide while full size mattresses and bed frames only measures 54 inches wide.
So if you are okay with a three inch overhang then you are good to go.
Have someone help you and use a tape measure to make it easier.
In contrast a standard full size mattress is approximately 53 inches wide by 75 inches long.
People have been fitting headboards to frames this way for years.
Here s what you ll need to get it done.
Since the metal bed frame dimensions are set for a full size mattress you will need to loosen the fasteners and make the bed frame 6 inches wider and 5 inches longer so the queen size mattress fits.
If you have a box spring that has an adjustable metal frame then you can easily loosen its fasteners to the dimensions of your queen sized bed.
Although 6 inches may seem like a lot it really isn t when you split the difference between each side.
If you re upgrading from a full size mattress to queen you can easily attach your existing headboard to the larger bed frame.
The four sided metal queen size bed frame that adjusts to variable widths is very simple to fit to a full size bed.
Push the frame inward on one of its sides to adjust it from 60 inches to 54 inches.
