We are all pleased with the Ironman Gravity 4000! It is sturdy, safe and very comfortable. I was concerned with the ankle holds as I have never used this style before. They are great even with bare feet. It adjusts easily enough to where our 9 and 10 year olds can adjust and use the table also. We researched for awhile before settling on this table. The memory foam back was worth the investment. There is no reason this table will meet our needs for as long as we will need it! We all feel great with no regrets!
