Full size bedframe with desk

I have a metal full size bedframe with a desk underneath. The bed is Coastal brand. We were the second owner and it is still usable but shows signs of use. Structurally secure and have all the screws to put it together. It'll take some patience and time without instructions. The side rails measure 56 and a half inches by 72 in tall. From one of the pictures you can see the item number and maybe get instructions or get a better idea how to reassemble. You may have the mattress if you want but it has some stains. Asking $50.00 hoping for a quick sale. The bed frame would cost hundreds if it were new. In Mesa, near Gilbert and Southern Any questions, please ask, Thanks
