over bed, hospital style table (Westcliff on Sea SS0)

fold down hospital style table with wheels and locking brakes, my mothers care home is in need of some of these for their residents, i had one, which i gave to my mother, have sourced 2 more from charity/junk shops, but haven't bee able to find anymore for months. If you have one you no longer need, i would be very grateful, they are used when a resident is ill in bed, or wants to spend time in their room crafting or colouring etc. Must have locks on the wheels.Thank you
