"Air Mattresses are not good and nursing staff."

I was admitted recently for diverticulitis in 7west in think. I am very satisfied with the treatment and the staff. The only bad thing that I have noticed that the nursing staff talks in their own language and also some of them hardly understand English. But one thing that I was not very happy was with the air mattresses. At present I having a serious dizziness problem. My head was spinning while lying on the bed. I was feeling very nauseous and was unable to eat anything. I complained but no action. So on the last day I was provided with a normal mattress before I was discharged. Apart from that I have no complaint. Many thanks
