Toddler beds for airplane travel?

Does anyone know of any travel beds that will fit on the floor of the bulkhead seats on airplanes? Or have any suggestions of what I can use besides blankets and pillows? I am going to be taking a 10 hour flight and although my daughter is already two and will have a seat, I would like for her to have more room and get better sleep. I have seen mothers lay their child on the floor on blankets and I am hoping I can find something that will make the hard floor more comfortable for her. Thank you!
