Bests & Worsts Reviews from Amazon

I have been using this pad for a few months now. I am a very heavy computer user, I typically spend 8-12 hours per day on the computer for work and sometimes an additional 4-6 for leisure, there have been times as well where I've probably been at my desk for more than a 24 hour period. Yes this is unhealthy, I am trying to be more active and that's where this pad comes to play. Long story short I was having debilitating lower back and leg pain. I wouldn't want to get up to stretch / walk and take breaks because it hurt more to get up. I have a decent chair, I bought a durable 24/7 operator chair, solid metal frame oversized cushions etc. I bought this pad and was skeptical as I am a larger person ~350lbs. I have next to no back / leg pain where before there would be days I had trouble walking 100 feet. I feel like this item has worked tremendously well for me and given me relief to becoming more active and healthy.
