What position to you take when reading (sit, lie down, on back, sit in chair)?

I usually read lying down with my back on the bed in a supine position or on my side so I can prop the phone (for ebooks) Ort the book on my bed for support

I usually sit up in a stair to stay alert and awake. But I also like to sit, legs stretched and relaxed, on the sofa, very comfortable and relaxing. I don't prefer to read just before sleeping or while laying in bed, because it makes me sleepy.
