Twin XL to king pop up trundle bed (Farmington Hills)

Hello, I have two twin xl mattresses, 38" x 80" in size. Their height is at least 6". We are searching for a daybed with a pop up or a trundle that pops up to make a king size bed when both mattresses are together. We CAN NOT use a regular twin trundle bed because that is 38" x 75", which is 5 inches too short. Please measure the length of the frame before offering as we do not have standard twin mattresses. It does not have toook like the picture, we inclded the picture as a reference only. Thanks for reading our post!
