At the back of the Adult Chemo room are a series of big red armchairs, watched over by a beautiful sculpted portrait on a plinth. They're square and quite soft, and were my go-to seat usually as they were near outlets (got to have a phone charging outlet if you're going to be in all day!) and also good to curl up and sleep in. I caught someone else doing the same one day.
Sadly they're now off limits to most patients, only used for those with certain particular conditions.
