Similar. I do powerlifting, i have a great squat and regularly use it for relaxing or doing things at home in a comfortable pose.
My back still has issues from sitting all day to program.

Lie on your back. Knees bent / legs up, so your back is fully supported by the floor. Arms at your sides, hands on your stomach or whatever the most neutral position is. Small pillow / book under your head to keep that portion of your spine properly curved.

I'm actually surprised by the legs part since i would've thought proper pose is legs down.
