As the title says, anyone using this bench? It doesn’t get the best reviews, but I don’t completely understand the issue with the wobble. Is it from uneven legs/feet or is it the way the pad is mounted. I feel like I could fix the wobbling issue but would like to understand it better before buying. The 1000 bench looks like it doesn’t lie completely flat and I’d rather not have to keep 2 benches. TIA.
