A cinemagoer died after his neck got trapped in an electronic footrest as he searched for his phone and keys, an inquest heard.
Ateeq Rafiq, 24, had been in a "Gold Class" seat at the Vue multiplex at Star City, Birmingham, last March.
His wife and staff spent 15 minutes trying to free him from the mechanism, a jury heard.
Coroner Emma Brown said Mr Rafiq died from "catastrophic" brain injuries after suffering a cardiac arrest.
Ayesha Sardar told the inquest her husband "went fully under the seat with just his legs sticking out" while reaching for his possessions at the end of the film.
Jurors heard the footrest was initially in a raised position but started to come down "very quickly".
'He was blue'
Mrs Sardar noticed it descended and tried unsuccessfully to hold it up before running for help.
Cinema staff then attempted to release Mr Rafiq for 15 minutes while she was taken outside, she said.
Staff eventually managed to free Mr Rafiq by removing a bolt from the seat, which had trapped either the back or right side of his neck, the inquest was told.
Mrs Sardar said she "ran back in" when she heard he was not breathing, and "saw that he was blue".
Mr Rafiq, from Aston, Birmingham, died in hospital a week later.
His cause of death was confirmed as a cardiac arrest following compression of the neck.
Charles Simmons-Jacobs, from the Health and Safety Executive (HSE), said he found it was "impossible" to lift eight of the footrests in the 52-seat theatre.
The seats only work when a customer was seated, he said, and after they vacated the control box waited four seconds before returning to a vertical position.
Mr Rafiq's seat had blown a fuse in its control box, he said, adding that the force that came down on him would have been the equivalent of three-quarters of a tonne.
Mrs Sardar said her husband was "always happy and positive".
"His smile was the kindest and his heart was the greatest," she said.
The inquest, due to last a week, continues.
