sturdy wood floor easel (Town Cntr. Mountlake. Terrace)

I’m looking for a sturdy, non-wobbly wood floor easel, ideally one that folds flat for storage. It doesn’t have to look exactly like the one in the picture but it does need to be very stable, heavy enough so my very active and curious cat can’t knock it over but not so heavy that this old lady can’t carry it. Thanks.
