We purchased this sand bag to put in my office when I was pregnant with twins last year. This sand bag helped me to have some good napping time. But it was harder than what I thought. I was 110lbs and I could not easily "shape" it as a form of chair by my weight. I would need my husband to make Yogibo a form of "chair", then I could sit on it.  Overall, I like it. I kept it for my twin girls now. I hope they will like it too.
