I was concerned this would not have support spines running on the underside of this barrel, but was relieved to see it was well reinforced. I included a photo of the underside, which was what I wanted to see before I made my purchase, but wasn’t available. It is made in China and I am happy with the quality and sturdiness of it. The only thing I found odd and of lower quality is the two side handles, they are plastic. I will probably replace them with metal ones just for peace of mind. The padding on the barrel is the perfect amount, the sides are real wood and screws that are visible look to be of good quality. I have already used this alone and with my reformer many times and it has been wonderful. No creaks or scary noises come from it as you go through your movements. My husband (210lb) plopped down on it and almost gave me a heart attack, I thought he would crack it in two, but it was fine. That being said, I wouldn’t recommend plopping down on it. This is a great purchase, I love it, my abs not so much. ?
