NRS DUO Walking Trolley (Hornsey N8)

Used, briefly and always indoors, by my mother-in-law following a hip replacement.
The two trays are both removable and the height can be adjusted by popping out the four grey clips on the legs and sliding the bottom poles up or down to get the height you want.
It's in excellent condition and would have gone to a charity shop if they were allowed to accept these things.
To help me work out if you really want this item (and aren't an auto-reply), please let me know who will be using the trolley and why.
Thanks.
