Please tell me the correct way to sit seiza

Question

Is Seiza sitting cross-legged or is it sitting above your bent upper and lower legs which aren't crossed?

Answer 1

Here are some common sitting positions. At my zendo, we sit in Seiza, Lotus, or Half-lotus.

Answer 2

Essentially kneeling all the way down so thighs touch calves. Some schools cross the big toes, some don't.

So the second description in your question.
