No. I have lower back disc problems and have a lot of trouble doing crunches, which is what the ab lounge essentially does. Crunches bend at the lower back and abs. The exercises I do/recommend bend at the hips and you use your ab muscles to keep your back straight. Crunches are typically face up or nearly so (though some gym machines have you sit up and then bend forward) and ab bridging exercises (what I do/recommend) are typically face down or nearly so. The most well known ab bridge is the plank.
