My surgery is approaching and I still don't have a chair with arms. We have wooden chairs on the deck with sturdy arms and have to bring one in to see if it will work or if I have to buy one. Any thoughts of what to get if I have to buy one? Not sure if I should be looking at office waiting room chairs or an armchair. Also I bought a 4" foam cushion to put on it and the couch. It will be great on the couch but is too high for my chair I sit at now the table and is too firm. Thinking I should get a 3" one. Any ideas on which would be an appropriate chair and cushion are welcome. Thanks so much!
