Life-long clinical depression causes husband to slide out of bed. He isn't hurt. He goes to bed later than he should, cannot move to the center because he has a subpubic catheter bag that has to hand over the side of the bed. Additionally, he thrashes around all night. Sheets, blankets, all bedding is on the floor in the morning.
He has a bar assist about 18 inches wide. It often is pushed out of place by rolling forcefully against it. I've tried using two assists, but he won't tolerate that because I have to place the second one when he is getting in bed. Likewise, rails would require being put on after he is in bed because he can't move with any agility. Have also tried putting the mattress on the floor; that doesn't allow the cath bag to hang lower than the bladder.
I'd welcome any suggestions!
He could still get into bed as it is not that high to get over if you sit and bring your legs over it but it might be enough of a "bump" that he could not roll over it.
Do you think a wedge would work, again same concept but rolling "up hill" on a wedge would be a bit more difficult. There are different size wedges but you could make your own with some foam from a fabric store that carries upholstery supplies.
You might try raising the legs on his side of the bed, yes the bed would be on a tilt. But again riling up hill would be more difficult than rolling off the bed if it is flat.
An adjustable base on the bed might work, if the head of the bed is raised a bit and the foot raised a bit it might encourage back sleeping so there would be less rolling around.
Last suggestion...I could loan you my 2 cats. One sleeps at my left hip the other at the right thigh. I can not move at all!
