Indoor heating season starting

[Neil jones]

Just finished a tabletop in walnut and now I'm paranoid about it warping as we start running the heat. I finished it with three coats of poly about a week ago. This is my first large piece going through a full winter in a heated house. Should I be concerned or am I overthinking? the wood was acclimated to my shop for about 2 months before milling

Walnut is pretty stable compared to other hardwoods, so you're probably fine and I know that warping is more about uneven moisture content or grain orientation when you built it

How wide is the top, and is it one solid piece or a glued-up panel? wider pieces move more, obviously
