What support?

I am at the end of my pregnancy and thought this would alleviate some of my back stress at work (As an RN). I ordered according to the recommended size chart but when I had it come it was HUGE!!!! I am not a small woman but if that was an XL, I must normally be a size 1. Yeah right. I double checked the sizes and had ordered correctly according to their charts. Anyway, the thing was useless, it took forever to arrive so I couldn't reorder in a timely manner, and it looks adjustable, but good luck with that. I would definitely recommend NOT buying this product on-line.
