Lumbar support fully envelops back.
My feet don’t hang off the recliner when reclined.
I am 5’10 210 and the chair engulfs me.
My head doesn’t come close to going over the high back. 
The chair reclines literally all the way back and your feet above your heart.
I’d have to say for the price this chair is perfect, and I’ve owned many couches and recliners. 
Lazy boy is the way to go. 
Oh, and the material breaths, I never get hot.
