Bedside rugs

DH has just gone ballistic because he "nearly" (according to,him) tripped over "that bloody mat" I.e.a (washable) bedside rug. Not thick, not sticky up , but there for a variety of reasons not least being a pale gold bedroom carpet (my stupid idea) and that because he can get sick in the night, a plastic washing up bowl is often kept beside the bed. When he was really poorly he had to sit on the edge of the bed to use a bottle. Nuff said.
Added to that, I had noticed that "his" side was getting grey just by the bed because it presumably gets more "footfall". He always wears felt Birkenstocks as slippers in the house, never outdoor shoes but even so.
AIBU to think it is a good idea rather than have a grubby potentially stained carpet?
(I should add he often doesn't pick his feet up very well, so I bet that was part of it )
