I received this bed with damage. I'm assuming due to shipping. I have a queen size mattress and it did not fit my queen size mattress. It's so tight that I had to smush my mattress down and it's nearly impossible to put sheets on. The instructions says full size queen size. If you have a queen size bed, just don't purchase this frame. Choose another frame. It was very easy to put together but I personally am not very happy with this purchase. I will be purchasing a different bed frame at another time. Again, this is not queen size mattress friendly even when you select the queen size.
