I have a very difficult time with metal arms on chairs of any kind. Not just because I have fibromyalgia, but because they are just plain uncomfortable and, they can get hot in the direct sun. We do have our lounge chairs under the canopy so they are somewhat shaded, but I still needed something to cover the arm rests. The arms on the lounge chairs aren't very wide, so my brilliant idea was to find a way to cover them, but make them removable for washing and winter storage.
Our chairs are a dark brown color, but since we're not entertaining royalty anytime soon, it's not a big deal.
So today I ordered some dark gray Velcro seatbelt covers and I think they will work nicely to solve my problem. And hey, the price was right too.
