A mother of four left paralysed after being “catapulted” from her bed while having sex is suing the manufacturer for seven-figure damages at the High Court.

Claire Busby suffered life-changing damage to her spine after she toppled off the end of the “defective” bed while switching positions during intercourse.

The 46-year-old from Maidenhead, Berks, appeared at the High Court in a wheelchair yesterday, where she is taking legal action against Berkshire Bed Company, trading as Beds Are Uzzz.

The court heard the bed was one of five delivered to Ms Busby's then home in August 2013 when she was renovating the property in Theresa May’s constituency. Ms Busby, a successful businesswoman in the property industry, was injured just a week after the bed's delivery.

She told the court that she was kneeling in the middle of the bed performing a sexual act on her partner, John Marshall, when she decided to move position and "swung her legs" from underneath her, before laying back on the bed.

At that point, she said the bed gave way and she fell off the end, landing dangerously on her head.

“I was positioned kneeling over him,” she told Judge Barry Cotter QC.

“I was kneeling over him and my right hand was touching him, maybe my left hand was touching his leg. I was half way down the bed.
