I love the idea of using an office chair with wheels. I have one that I almost never use since I retired. I'm going to move it up from the basement office to the kitchen and see how that goes.I'm right there with both of you Taxi and GG. My stamina both in and out of the kitchen is really diminished. Standing for more than a few minutes just isn't in the cards anymore. I have an office chair in the kitchen that helps and scoots across the floor easily. I can sit to watch a pot on the stove and only need to stand when needed.
Thankfully, the SC does a lot of the prep work and seems to enjoy doing it.
Like Bea..."I'm over the hill and picking up speed" so my goal for the year is just being able to maintain what I already do.
I have a bar stool. I keep forgetting to use it in the kitchen. Both of these ideas should help.
