A woman was left paralyzed after being "catapulted" from her new bed during sex, a high court in London heard Monday. The woman was suing the manufacturer for £1 million ($13, 17,405) in damages.

Claire Busby, 46, suffered a serious injury to her spine after she toppled off the end of the super king-size double divan as she shifted her position, the court was told. She claimed the bed was in a "defective state” when the accident took place and that she was taking legal action against Berkshire Bed Company, trading as Beds Are Uzzz.

Judge Barry Cotter was told the main questions in the case were whether there were defects with the bed and if Busby's injuries were caused by them, BBC reported.

The bed was one of five delivered to her then home in August 2013 when she was renovating the property. She was injured a week after, while having sex with her partner John Marshall.

Busby told the court she was kneeling in the middle of the bed performing a sex act when she “swung her legs” from underneath her, before laying back on the bed. At that point, the bed gave way and she toppled off the end, landing on her head, she claimed.

“I spun around, I put my hand down and then I felt like I was catapulted off the back of the bed. My head hit the floor, I fell to the side and then I heard like a spring in my body snap, it felt like,” she said, Metro reported.

Natalie Busby, her sister, said she visited the property two days after the accident and noticed the bed did not have “two feet.” However, she decided not to discuss the matter until later as her sister was in a bad state.

"Claire wasn't in any fit state to be having a conversation, at one point she had two heart attacks in 24 hours. It was touch and go whether she was going to make it,” she said, Mirror reported.

She went on to claim the two divans which made up the base of the bed were not properly fastened together and two feet were missing from the end of the bed.

Busby’s lawyer said, "It is the claimant's case that the point at which she left the bed is precisely the location where the different height of the two divans was at its maximum. It represented the area where the mattress was most likely to fall away due to the fact that it was partially unsupported,” Telegraph reported.

It was "accepted that the particular circumstances of the accident are unusual," but it was enough for there to have been "some foresight of some loss of balance in the use of the bed" for the firm to be found liable, he added.

The manufacturer, however, denied the liability for Busby’s injuries and argued the bed was properly assembled.

Neil Block, representing the firm, said, "It is overwhelmingly likely that, whatever her actions, they were too close to the edge of the bed and she simply lost balance and toppled backwards."

The hearing of the case continues.
