Bed Safety Rail (Ware SG12)

Not sure what the title of this post should be. It’s a device that helps prevent someone falling out of bed. The open frame part sits under the mattress and the part with the bars projects above the level of the mattress. This part can be folded down as required. The whole thing is secured in place with the strap. The label says it should never be used for children. It was bought for my elderly mother after she injured herself falling out of bed.
