change both of them
Yes, a full size mattress will fit on a queen size bed frame. It may be just a tad bit smaller than the frame, but not too noticeable. I have a full mattress and use full/queen sheets and bedding all the time.
I believe not dear, a full sized frame is smaller than a queen bed frame, it will go on it, but it will hang off. Good luck =)
No.
Only if the frame will adjust out to the width of the king. King mattress sets are 16 inches wider than a queen.
No. Two twin size mattress will fit a king size bed frame.
it depends if your mattress is a bit big, but most likely not
No. If you have a box spring to support the sleeping mattress, the answer is yes, but not a sleeping mattress by itself. The frame is too short and the foot end of the mattress will hang down and touch the floor.
No such thing. You might be referring to Split Queen Box Spring.... This is just a wrong answer. A split queen mattress is a queen-sized mattress that has been split into two individual mattresses, each of which is half-width. I have one: The Otis Liberty Queen Split Mattress.
In the UK a Queen size mattress is 4ft6inches, so you really should use a divan box base that measures the same. If you use a 5ft King Size you may affect the stability of the mattress on top of the divan base or frame.
yes but it wouldn't fill it out it will look kinda weird
A Regular Queen size bed measures 60" x 80" An Olympic Queen size bed measures 66" x 80" Depending on your headboard frame, you would have an overlap because of the extra six inches in width. If you put the mattress on a pedestal, with the headboard behind it, the look would be iffy.
