Desk chair for child/small adult (Torrisholme LA4)

Originally from Ikea, fairly small desk chair. Daughter is now about 5’8” and size 10 and it’s just about useable but much too small to be comfy. In good condition, padding is not squashed and gas lift works, there are just some marks from paint and a water mark across the front of the seat from where I used carpet cleaner to get the paint off!
