An obese US man had to be cut from a chair he had been sitting in for two years after his body became fused to it, local media reported.

Police told WTRF news that the Ohio man's skin had become fused to the seat of the chair, which was covered in urine, faeces and maggots.

The man's girlfriend brought him food for two years as he sat in his own waste in the filthy apartment they shared with another man, police said.

They called for help on Sunday morning when he was unresponsive and had to cut a hole in the house to get him out of the building so they could get him to the hospital.
