This is a GREAT piece of equipment! So wish I bought this instead of the full inversion table which didn't lock and caused my near death accident. My back is finally getting some relief. I'm a big guy 260 6"3' and feel secure in it. My head is close to the ground... about an inch or two off but that's fine with me. Exiting the equip is a bit iffy until you get the hang of it. be careful. If you're looking for an 90 90 this is the one for the money. Teeter has a DEX I but it's double the price. Enjoy
After putting this together and trying it out, I heard cracks and pops all the way down my neck and spine right away, so it does what I bought it for and feels stable enough to hold my weight and be simple to use. Word of caution: if you set the leg pads close to the middle so that the adjustment pole is sticking out, dismount carefully! Neglecting to swing your leg over that adjustment pole will result in some ugly bruises on the inside of your thigh.
